Detailed Description

Specialisation of HighLevelGpuProgram to provide support for Vulkan Shader Language.

Remarks: Vulkan has no target assembler or entry point specification like DirectX 9 HLSL. Vertex and Fragment shaders only have one entry point called "main". When a shader is compiled, microcode is generated but can not be accessed by the application. Vulkan also does not provide assembler low level output after compiling. The Vulkan Render system assumes that the Gpu program is a Vulkan Gpu program so VulkanProgram will create a VulkanGpuProgram that is subclassed from VulkanGpuProgram for the low level implementation. The VulkanProgram class will create a shader object and compile the source but will not create a program object. It's up to VulkanGpuProgram class to request a program object to link the shader object to.

Member Function Documentation

◆ _dirtyState()

virtual void Ogre::Resource::_dirtyState ( )

virtualinherited

Manually mark the state of this resource as having been changed.

Remarks: You only need to call this from outside if you explicitly want derived objects to think this object has changed.

See also: getStateCount.

◆ _fireLoadingComplete()

virtual void Ogre::Resource::_fireLoadingComplete ( bool wasBackgroundLoaded )

virtualinherited

Firing of loading complete event.

Remarks: You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.

Parameters

wasBackgroundLoaded Whether this was a background loaded event

◆ _firePreparingComplete()

virtual void Ogre::Resource::_firePreparingComplete ( bool wasBackgroundLoaded )

virtualinherited

Firing of preparing complete event.

Remarks: You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.

Parameters

wasBackgroundLoaded Whether this was a background loaded event

◆ _fireUnloadingComplete()

virtual void Ogre::Resource::_fireUnloadingComplete ( )

virtualinherited

Firing of unloading complete event.

Remarks: You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.

◆ _getBindingDelegate()

GpuProgram* Ogre::HighLevelGpuProgram::_getBindingDelegate ( )

inlineoverridevirtualinherited

Returns the GpuProgram which should be bound to the pipeline.

Remarks: This method is simply to allow some subclasses of GpuProgram to delegate the program which is bound to the pipeline to a delegate, if required.

Reimplemented from Ogre::GpuProgram.

Reimplemented in Ogre::GLSLShader, and Ogre::UnifiedHighLevelGpuProgram.

References Ogre::SharedPtr< T >::getPointer().

◆ _notifyOrigin()

virtual void Ogre::Resource::_notifyOrigin ( const String & origin )

inlinevirtualinherited

Notify this resource of it's origin.

◆ addListener()

virtual void Ogre::Resource::addListener ( Listener * lis )

virtualinherited

Register a listener on this resource.

See also: Resource::Listener

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ calculateSize()

size_t Ogre::HighLevelGpuProgram::calculateSize ( ) const

overridevirtualinherited

Calculate the size of a resource; this will only be called after 'load'.

Reimplemented from Ogre::GpuProgram.

Reimplemented in Ogre::GLSLShader, and Ogre::UnifiedHighLevelGpuProgram.

◆ changeGroupOwnership()

virtual void Ogre::Resource::changeGroupOwnership ( const String & newGroup )

virtualinherited

Change the resource group ownership of a Resource.

Remarks: This method is generally reserved for internal use, although if you really know what you're doing you can use it to move this resource from one group to another.

Parameters

newGroup Name of the new group

◆ cleanupDictionary()

static void Ogre::StringInterface::cleanupDictionary ( )

staticinherited

Cleans up the static 'msDictionary' required to reset Ogre, otherwise the containers are left with invalid pointers, which will lead to a crash as soon as one of the ResourceManager implementers (e.g.

MaterialManager) initializes.

◆ compile()

bool Ogre::VulkanProgram::compile	(	const bool	checkErrors,
		const bool	bReflectingArrays = `false`
	)

Compile source into shader object.

◆ copyParametersTo()

virtual void Ogre::StringInterface::copyParametersTo ( StringInterface * dest ) const

inlinevirtualinherited

Method for copying this object's parameters to another object.

Remarks: This method takes the values of all the object's parameters and tries to set the same values on the destination object. This provides a completely type independent way to copy parameters to other objects. Note that because of the String manipulation involved, this should not be regarded as an efficient process and should be saved for times outside of the rendering loop.

: Any unrecognised parameters will be ignored as with setParameter method.

Parameters

dest	Pointer to object to have it's parameters set the same as this object.

References Ogre::StringInterface::setParameter().

◆ createParameters()

GpuProgramParametersSharedPtr Ogre::VulkanProgram::createParameters ( )

overridevirtual

Overridden from GpuProgram.

Reimplemented from Ogre::HighLevelGpuProgram.

◆ debugDump()

void Ogre::VulkanProgram::debugDump ( String & outString )

◆ escalateLoading()

virtual void Ogre::Resource::escalateLoading ( )

virtualinherited

Escalates the loading of a background loaded resource.

Remarks: If a resource is set to load in the background, but something needs it before it's been loaded, there could be a problem. If the user of this resource really can't wait, they can escalate the loading which basically pulls the loading into the current thread immediately. If the resource is already being loaded but just hasn't quite finished then this method will simply wait until the background load is complete.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ fillPipelineShaderStageCi()

void Ogre::VulkanProgram::fillPipelineShaderStageCi ( VkPipelineShaderStageCreateInfo & pssCi )

◆ getBufferRequiredSize()

uint32 Ogre::VulkanProgram::getBufferRequiredSize ( ) const

In bytes.

◆ getConstantDefsBindingParams()

const map<uint32, VulkanConstantDefinitionBindingParam>::type& Ogre::VulkanProgram::getConstantDefsBindingParams ( ) const

inline

◆ getCreator()

virtual ResourceManager* Ogre::Resource::getCreator ( )

inlinevirtualinherited

Gets the manager which created this resource.

◆ getDefaultParameters()

virtual GpuProgramParametersSharedPtr Ogre::GpuProgram::getDefaultParameters ( )

virtualinherited

Get a reference to the default parameters which are to be used for all uses of this program.

Remarks: A program can be set up with a list of default parameters, which can save time when using a program many times in a material with roughly the same settings. By retrieving the default parameters and populating it with the most used options, any new parameter objects created from this program afterwards will automatically include the default parameters; thus users of the program need only change the parameters which are unique to their own usage of the program.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Remarks: Call this method with the name of a parameter to retrieve a string-format value of the parameter in question. If in doubt, check the parameter definition in the list returned from getParameters for the type of this parameter. If you like you can use StringConverter to convert this string back into a native type.

Parameters

name	The name of the parameter to get

Returns: String value of parameter, blank if not found

References Ogre::ParamCommand::doGet().

◆ getParameters()

const ParameterList& Ogre::StringInterface::getParameters ( ) const

inherited

◆ getPassFogStates()

bool Ogre::VulkanProgram::getPassFogStates ( ) const

overridevirtual

Returns whether a fragment program wants fog state to be passed through fixed pipeline low level API rendering calls (default true, subclasses can override)

Remarks: On DirectX, shader model 2 and earlier continues to have fixed-function fog applied to it, so fog state is still passed (you should disable fog on the pass if you want to perform fog in the shader). In OpenGL it is also common to be able to access the fixed-function fog state inside the shader.

overridevirtual

Overridden.

Reimplemented from Ogre::GpuProgram.

◆ getPreprocessorDefines()

inlinevirtualinherited

Gets the assembler source for this program.

◆ getSourceFile()

inline

◆ getStateCount()

virtual size_t Ogre::Resource::getStateCount ( ) const

inlinevirtualinherited

Returns the number of times this resource has changed state, which generally means the number of times it has been loaded.

Objects that build derived data based on the resource can check this value against a copy they kept last time they built this derived data, in order to know whether it needs rebuilding. This is a nice way of monitoring changes without having a tightly-bound callback.

◆ getSyntaxCode()

virtual const String& Ogre::GpuProgram::getSyntaxCode ( ) const

inlinevirtualinherited

Gets the syntax code for this program e.g.

arbvp1, fp20, vs_1_1 etc

◆ hasCompileError()

virtual bool Ogre::GpuProgram::hasCompileError ( ) const

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ hasDefaultParameters()

virtual bool Ogre::GpuProgram::hasDefaultParameters ( ) const

Returns whether this geometry program requires adjacency information from the input primitives.

◆ isBackgroundLoaded()

virtual bool Ogre::Resource::isBackgroundLoaded ( ) const

inlinevirtualinherited

Returns whether this Resource has been earmarked for background loading.

Remarks: This option only makes sense when you have built Ogre with thread support (OGRE_THREAD_SUPPORT). If a resource has been marked for background loading, then it won't load on demand like normal when load() is called. Instead, it will ignore request to load() except if the caller indicates it is the background loader. Any other users of this resource should check isLoaded(), and if that returns false, don't use the resource and come back later.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ isLoaded()

virtual bool Ogre::Resource::isLoaded ( ) const

inlinevirtualinherited

Returns true if the Resource has been loaded, false otherwise.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Is this resource manually loaded?

◆ isMorphAnimationIncluded()

virtual bool Ogre::GpuProgram::isMorphAnimationIncluded ( ) const

Remarks: If this returns true, OGRE will not blend the geometry according to morph animation, it will expect the vertex program to do it.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ isPoseAnimationIncluded()

virtual bool Ogre::GpuProgram::isPoseAnimationIncluded ( ) const

inlinevirtualinherited

Returns whether a vertex program includes the required instructions to perform pose animation.

◆ prepare()

virtual void Ogre::Resource::prepare ( bool backgroundThread = false )

virtualinherited

Prepares the resource for load, if it is not already.

One can call prepare() before load(), but this is not required as load() will call prepare() itself, if needed. When OGRE_THREAD_SUPPORT==1 both load() and prepare() are thread-safe. When OGRE_THREAD_SUPPORT==2 however, only prepare() is thread-safe. The reason for this function is to allow a background thread to do some of the loading work, without requiring the whole render system to be thread-safe. The background thread would call prepare() while the main render loop would later call load(). So long as prepare() remains thread-safe, subclasses can arbitrarily split the work of loading a resource between load() and prepare(). It is best to try and do as much work in prepare(), however, since this will leave less work for the main render thread to do and thus increase FPS.

Parameters

backgroundThread Whether this is occurring in a background thread

◆ reload()

virtual void Ogre::Resource::reload ( LoadingFlags flags = LF_DEFAULT )

virtualinherited

Reloads the resource, if it is already loaded.

Remarks: Calls unload() and then load() again, if the resource is already loaded. If it is not loaded already, then nothing happens.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram, and Ogre::v1::Mesh.

◆ removeListener()

virtual void Ogre::Resource::removeListener ( Listener * lis )

virtualinherited

Remove a listener on this resource.

See also: Resource::Listener

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ resetCompileError()

virtual void Ogre::GpuProgram::resetCompileError ( )

inlinevirtualinherited

Reset a compile error if it occurred, allowing the load to be retried.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ setAdjacencyInfoRequired()

virtual void Ogre::GpuProgram::setAdjacencyInfoRequired ( bool r )

inlinevirtualinherited

Sets whether this geometry program requires adjacency information from the input primitives.

◆ setAutoReflectArrayBindingsInRootLayout()

void Ogre::VulkanProgram::setAutoReflectArrayBindingsInRootLayout ( bool bReflectArrayRootLayouts )

overridevirtual

Set to true to reflects the shader looking for array bindings (e.g.

uniform texture2D myTex[123]) to patch the Root Layout

Parameters

bReflectArrayRootLayouts When true (default), reflect the shader to see if the RootLayout needs patching to include array bindings

When false, we assume the RootLayout doesn't need patching and array bindings are correct. Failure to do this right may result in shader compiler errors OR everything appears fine but Vulkan Validation Layers detect it

In debug builds we will validate and reflect anyway to detect wrong usage

Reimplemented from Ogre::GpuProgram.

◆ setBackgroundLoaded()

virtual void Ogre::Resource::setBackgroundLoaded ( bool bl )

inlinevirtualinherited

Tells the resource whether it is background loaded or not.

Remarks

See also: Resource::isBackgroundLoaded . Note that calling this only defers the normal on-demand loading behaviour of a resource, it does not actually set up a thread to make sure the resource gets loaded in the background. You should use ResourceBackgroundLoadingQueue to manage the actual loading (which will call this method itself).

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ setBuildParametersFromReflection()

void Ogre::GpuProgram::setBuildParametersFromReflection ( bool buildParams )

inlineinherited

◆ setComputeGroupDimensions()

virtual void Ogre::GpuProgram::setComputeGroupDimensions ( Vector3 dimensions )

inlinevirtualinherited

Sets the number of process groups dispatched by this compute program.

◆ setEnableIncludeHeader()

void Ogre::HighLevelGpuProgram::setEnableIncludeHeader ( bool bEnable )

inherited

Whether we should parse the source code looking for include files and embedding the file.

Disabled by default to avoid slowing down when #include is not used. Not needed if the API natively supports it (D3D11).

Remarks

Single line comments are supported: #include "MyFile.h" --> won't be included.

        Block comment lines are not supported, but may not matter if
        the included file does not close the block:
            / *
                #include "MyFile.h" --> file will be included anyway.
              /

        Preprocessor macros are not supported, but should not matter:
            #if SOME_MACRO
                #include "MyFile.h" --> file will be included anyway.
            #endif
    @par
        Recursive includes are supported (e.g. header includes a header)
    @par
        Beware included files mess up error reporting (wrong lines)
    @param bEnable
        True to support #include. Must be toggled before loading the source file.

◆ setManuallyLoaded()

virtual void Ogre::Resource::setManuallyLoaded ( bool isManual )

inlinevirtualinherited

Set "Is this resource manually loaded?".

◆ setManualNamedConstants()

virtual void Ogre::GpuProgram::setManualNamedConstants ( const GpuNamedConstants & namedConstants )

virtualinherited

Allows you to manually provide a set of named parameter mappings to a program which would not be able to derive named parameters itself.

Remarks: You may wish to use this if you have assembler programs that were compiled from a high-level source, and want the convenience of still being able to use the named parameters from the original high-level source.

See also: setManualNamedConstantsFile

◆ setManualNamedConstantsFile()

virtual void Ogre::GpuProgram::setManualNamedConstantsFile ( const String & paramDefFile )

virtualinherited

Specifies the name of a file from which to load named parameters mapping for a program which would not be able to derive named parameters itself.

Remarks: You may wish to use this if you have assembler programs that were compiled from a high-level source, and want the convenience of still being able to use the named parameters from the original high-level source. This method will make a low-level program search in the resource group of the program for the named file from which to load parameter names from. The file must be in the format produced by GpuNamedConstants::save.

◆ setMorphAnimationIncluded()

virtual void Ogre::GpuProgram::setMorphAnimationIncluded ( bool included )

inlinevirtualinherited

Sets whether a vertex program includes the required instructions to perform morph animation.

Remarks: If this is set to true, OGRE will not blend the geometry according to morph animation, it will expect the vertex program to do it.

◆ setNumClipDistances()

void Ogre::GpuProgram::setNumClipDistances ( const uint8 numClipDistances )

inherited

Sets the number of clip distances this shader uses.

Only valid for vertex shaders. Default is 0

◆ setParameter()

virtual bool Ogre::StringInterface::setParameter	(	const String &	name,
		const String &	value
	)

virtualinherited

Generic parameter setting method.

Remarks: Call this method with the name of a parameter and a string version of the value to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters

name	The name of the parameter to set
value	String value. Must be in the right format for the type specified in the parameter definition. See the StringConverter class for more information.

Returns: true if set was successful, false otherwise (NB no exceptions thrown - tolerant method)

Referenced by Ogre::StringInterface::copyParametersTo().

◆ setParameterList()

virtual void Ogre::StringInterface::setParameterList ( const NameValuePairList & paramList )

virtualinherited

Generic multiple parameter setting method.

Remarks: Call this method with a list of name / value pairs to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters

paramList Name/value pair list

◆ setPoseAnimationIncluded()

virtual void Ogre::GpuProgram::setPoseAnimationIncluded ( ushort poseCount )

inlinevirtualinherited

Sets whether a vertex program includes the required instructions to perform pose animation.

Remarks: If this is set to true, OGRE will not blend the geometry according to pose animation, it will expect the vertex program to do it.

Parameters

poseCount The number of simultaneous poses the program can blend

◆ setPrefabRootLayout()

void Ogre::GpuProgram::setPrefabRootLayout ( const PrefabRootLayout::PrefabRootLayout & prefab )

inherited

Sets a prefab root layout, mostly meant for low level materials (e.g.

postprocessing) so that users don't have to deal with Root Layouts unless they exceed defaults

Each prefab higher root layout supports more features but consumes more memory

◆ setPreprocessorDefines()

void Ogre::VulkanProgram::setPreprocessorDefines ( const String & defines )

inline

Sets the preprocessor defines use to compile the program.

◆ setReplaceVersionMacro()

void Ogre::VulkanProgram::setReplaceVersionMacro ( bool bReplace )

overridevirtual

When true:

On OpenGL: Finds the first occurrence of "ogre_glsl_ver_xxx" and only keeps "xxx" e.g. ogre_glsl_ver_330 becomes 330, ogre_glsl_ver_430 becomes 430

On Vulkan: Finds the first occurrence of "ogre_glsl_ver_xxx" and replaces it with "450"

This is disabled by default because we must scan the entire source and it's just wasted cycles when using Hlms.

However it is enabled by default on low level materials, because their source length tends to be very short and it is extremely useful/practical there

Parameters

bReplace

Reimplemented from Ogre::GpuProgram.

◆ setRootLayout()

void Ogre::VulkanProgram::setRootLayout	(	GpuProgramType	t,
		const RootLayout &	rootLayout
	)

overridevirtual

Sets a RootLayout programmatically, thus the shader source won't be parsed looking for one We will call validate()

Do not alter the type after calling this function.

This setting will be cleared if the program gets unloaded

Reimplemented from Ogre::GpuProgram.

◆ setSkeletalAnimationIncluded()

virtual void Ogre::GpuProgram::setSkeletalAnimationIncluded ( bool included )

inlinevirtualinherited

Sets whether a vertex program includes the required instructions to perform skeletal animation.

Remarks: If this is set to true, OGRE will not blend the geometry according to skeletal animation, it will expect the vertex program to do it.
