◆ setConfigOption()

void Ogre::VulkanRenderSystem::setConfigOption	(	const String &	name,
		const String &	value
	)

overridevirtual

Sets an option for this API.

Used to confirm the settings (normally chosen by the user) in order to make the renderer able to initialise with the settings as required. This may initialise the RenderWindowDescription or set some RenderSystem specific parameters. Called automatically by the default configuration dialog, and by the restoration of saved settings. These settings are stored and only activated when RenderSystem::_initialise or RenderSystem::reinitialise are called.

If using a custom configuration dialog, it is advised that the caller calls RenderSystem::getConfigOptions again, since some options can alter resulting from a selection.

Common options:

Key	Default	Description
Full Screen	false	Window full-screen flag
VSync	true	"vsync" in _createRenderWindow
VSync Interval	1	"vsyncInterval" in _createRenderWindow
sRGB Gamma Conversion	false	"gamma" in _createRenderWindow
FSAA	0	concatenation of "FSAA" and "FSAAHint" as in _createRenderWindow
Video Mode	-	Window resolution
Display Frequency	-	"displayFrequency" in _createRenderWindow
Content Scaling Factor	1.0	"contentScalingFactor" in _createRenderWindow

Reimplemented from Ogre::RenderSystem.

◆ bindGpuProgram()

void Ogre::VulkanRenderSystem::bindGpuProgram ( GpuProgram * prg )

◆ _createDepthBufferFor()

DepthBuffer* Ogre::VulkanRenderSystem::_createDepthBufferFor ( RenderTarget * renderTarget )

overridevirtual

Creates a DepthBuffer that can be attached to the specified RenderTarget.

Remarks: It doesn't attach anything, it just returns a pointer to a new DepthBuffer Caller is responsible for putting this buffer into the right pool, for attaching, and deleting it. Here's where API-specific magic happens. Don't call this directly unless you know what you're doing.

Implements Ogre::RenderSystem.

overridevirtual

Sets the provided viewport as the active one for future rendering operations.

This viewport is aware of it's own camera and render target. Must be implemented by subclass.

Parameters

vp	Pointer to the appropriate viewport.

Implements Ogre::RenderSystem.

◆ _setRenderTarget()

void Ogre::VulkanRenderSystem::_setRenderTarget ( RenderTarget * target )

overridevirtual

Set current render target to target, enabling its device context if needed.

Implements Ogre::RenderSystem.

◆ clearFrameBuffer()

override

◆ setScissorTest()

void Ogre::VulkanRenderSystem::setScissorTest	(	bool	enabled,
		const Rect &	rect = `Rect()`
	)

overridevirtual

Sets the 'scissor region' i.e.

the region of the target in which rendering can take place.

Remarks: This method allows you to 'mask off' rendering in all but a given rectangular area as identified by the parameters to this method.

Parameters

enabled	True to enable the scissor test, false to disable it.
rect	The location of the corners of the rectangle, expressed in pixels.

Implements Ogre::RenderSystem.

◆ setStencilState()

void Ogre::VulkanRenderSystem::setStencilState ( const StencilState & state )

overridevirtual

This method allows you to set all the stencil buffer parameters in one call.

Unlike other render states, stencilling is left for the application to turn on and off when it requires. This is because you are likely to want to change parameters between batches of arbitrary objects and control the ordering yourself. In order to batch things this way, you'll want to use OGRE's Compositor stencil pass or separate render queue groups and register a RenderQueueListener to get notifications between batches.

See also: RenderQueue

Implements Ogre::RenderSystem.

		Matrix4 &	dest,
		bool	forGpuProgram
	)

overridevirtual

Converts a uniform projection matrix to suitable for this render system.

Remarks: Because different APIs have different requirements (some incompatible) for the projection matrix, this method allows each to implement their own correctly and pass back a generic OGRE matrix for storage in the engine.

Implements Ogre::RenderSystem.

◆ _setDepthBias()

void Ogre::VulkanRenderSystem::_setDepthBias	(	float	constantBias,
		float	slopeScaleBias = `0.0f`
	)

overridevirtual

Sets the depth bias, NB you should use the Material version of this.

Remarks: When polygons are coplanar, you can get problems with 'depth fighting' where the pixels from the two polys compete for the same screen pixel. This is particularly a problem for decals (polys attached to another surface to represent details such as bulletholes etc.).

: A way to combat this problem is to use a depth bias to adjust the depth buffer value used for the decal such that it is slightly higher than the true value, ensuring that the decal appears on top.

Note: The final bias value is a combination of a constant bias and a bias proportional to the maximum depth slope of the polygon being rendered. The final bias is constantBias + slopeScaleBias * maxslope. Slope scale biasing is generally preferable but is not available on older hardware.

Parameters

constantBias	The constant bias value, expressed as a value in homogeneous depth coordinates.
slopeScaleBias	The bias value which is factored by the maximum slope of the polygon, see the description above. This is not supported by all cards.

◆ _setDepthBufferParams()

void Ogre::VulkanRenderSystem::_setDepthBufferParams	(	bool	depthTest,
		bool	depthWrite,
		CompareFunction	depthFunction
	)

overridevirtual

Sets the mode of operation for depth buffer tests from this point onwards.

Sometimes you may wish to alter the behaviour of the depth buffer to achieve special effects. Because it's unlikely that you'll set these options for an entire frame, but rather use them to tweak settings between rendering objects, this is an internal method (indicated by the '_' prefix) which will be used by a SceneManager implementation rather than directly from the client application. If this method is never called the settings are automatically the same as the default parameters.

Parameters

depthTest	If true, the depth buffer is tested for each pixel and the frame buffer is only updated if the depth function test succeeds. If false, no test is performed and pixels are always written.
depthWrite	If true, the depth buffer is updated with the depth of the new pixel if the depth test succeeds. If false, the depth buffer is left unchanged even if a new pixel is written.
depthFunction	Sets the function required for the depth test.

Implements Ogre::RenderSystem.

◆ _setDepthClamp()

void Ogre::VulkanRenderSystem::_setDepthClamp ( bool enable )

overridevirtual

Clamp depth values to near and far plane rather than discarding.

Useful for "shadow caster pancaking" or with shadow volumes

Reimplemented from Ogre::RenderSystem.

◆ _setCullingMode()

void Ogre::VulkanRenderSystem::_setCullingMode ( CullingMode mode )

overridevirtual

Sets the culling mode for the render system based on the 'vertex winding'.

A typical way for the rendering engine to cull triangles is based on the 'vertex winding' of triangles. Vertex winding refers to the direction in which the vertices are passed or indexed to in the rendering operation as viewed from the camera, and will either be clockwise or anticlockwise (that's 'counterclockwise' for you Americans out there ;) The default is Ogre::CULL_CLOCKWISE i.e. that only triangles whose vertices are passed/indexed in anticlockwise order are rendered - this is a common approach and is used in 3D studio models for example. You can alter this culling mode if you wish but it is not advised unless you know what you are doing.

You may wish to use the Ogre::CULL_NONE option for mesh data that you cull yourself where the vertex winding is uncertain or for creating 2-sided passes.

Implements Ogre::RenderSystem.

◆ _setAlphaRejectSettings()

void Ogre::VulkanRenderSystem::_setAlphaRejectSettings	(	CompareFunction	func,
		unsigned char	value,
		bool	alphaToCoverage
	)

overridevirtual

Sets the global alpha rejection approach for future renders.

By default images are rendered regardless of texture alpha. This method lets you change that.

Parameters

func	The comparison function which must pass for a pixel to be written.
value	The value to compare each pixels alpha value to (0-255)
alphaToCoverage	Whether to enable alpha to coverage, if supported

Implements Ogre::RenderSystem.

◆ setColourBlendState()

void Ogre::VulkanRenderSystem::setColourBlendState ( const ColourBlendState & state )

overridevirtual

Sets the global blending factors for combining subsequent renders with the existing frame contents.

Implements Ogre::RenderSystem.

◆ _setSampler()

void Ogre::VulkanRenderSystem::_setSampler	(	size_t	texUnit,
		Sampler &	s
	)

overridevirtual

set the sampler settings for the given texture unit

Implements Ogre::RenderSystem.

◆ createMultiRenderTarget()

MultiRenderTarget* Ogre::VulkanRenderSystem::createMultiRenderTarget ( const String & name )

inlineoverridevirtual

Create a MultiRenderTarget, which is a render target that renders to multiple RenderTextures at once.

Surfaces can be bound and unbound at will. This fails if mCapabilities->getNumMultiRenderTargets() is smaller than 2.
