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.

		FastArray< VkVertexInputAttributeDescription > &	outVertexInputs
	)		const

◆ 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.

Reimplemented from Ogre::GpuProgram.

◆ getPassSurfaceAndLightStates()

bool Ogre::VulkanProgram::getPassSurfaceAndLightStates ( ) const

overridevirtual

Returns whether a vertex program wants light and material states to be passed through fixed pipeline low level API rendering calls (default false, subclasses can override)

Remarks: Most vertex programs do not need this material information, however GLSL shaders can refer to this material and lighting state so enable this option

Reimplemented from Ogre::GpuProgram.

◆ getPassTransformStates()

bool Ogre::VulkanProgram::getPassTransformStates ( ) const

overridevirtual

Overridden.

Reimplemented from Ogre::GpuProgram.

◆ getPreprocessorDefines()

◆ getSpirv()

const std::vector<uint32>& Ogre::VulkanProgram::getSpirv ( ) const

inline

◆ 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.

◆ 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.

◆ unsetRootLayout()

void Ogre::VulkanProgram::unsetRootLayout ( )

overridevirtual

Reimplemented from Ogre::GpuProgram.

◆ updateBuffers()

void Ogre::VulkanProgram::updateBuffers	(	const GpuProgramParametersSharedPtr &	params,
		uint8 *RESTRICT_ALIAS	dstData
	)

dstData must be able to hold at least getBufferRequiredSize
