Member Function Documentation

◆ BeginOcclusionQuery()

ezGALOcclusionHandle ezGALCommandEncoder::BeginOcclusionQuery ( ezEnum< ezGALQueryType > type )

Starts an occlusion query. This function must be called within a render scope and EndOcclusionQuery must be called within the same scope. Only one occlusion query can be active at any given time.

Parameters

type	The type of the occlusion query.

Returns: A handle to be passed into EndOcclusionQuery.

See also: EndOcclusionQuery

◆ Clear()

void ezGALCommandEncoder::Clear	(	const ezColor &	clearColor,
		ezUInt32	uiRenderTargetClearMask = `0xFFFFFFFFu`,
		bool	bClearDepth = `true`,
		bool	bClearStencil = `true`,
		float	fDepthClear = `1.0f`,
		ezUInt8	uiStencilClear = `0x0u`
	)

Clears active rendertargets.

Parameters

uiRenderTargetClearMask Each bit represents a bound color target. If all bits are set, all bound color targets will be cleared.

◆ EndOcclusionQuery()

void ezGALCommandEncoder::EndOcclusionQuery ( ezGALOcclusionHandle hOcclusion )

Ends an occlusion query. The given handle must afterwards be passed into the ezGALDevice::GetOcclusionQueryResult function, which needs to be repeated every frame until results are ready.

Parameters

hOcclusion Value returned by the previous call to BeginOcclusionQuery.

See also: ezGALDevice::GetOcclusionQueryResult

◆ InsertFence()

ezGALFenceHandle ezGALCommandEncoder::InsertFence ( )

Inserts a fence. You need to flush commands to the GPU in order to be able to wait for a fence by either ending a frame or calling ezCommandEncoder::Flush explicitly.

Returns: A handle to be passed into ezGALDevice::GetFenceResult.

See also: ezGALDevice::GetFenceResult

◆ InsertTimestamp()

ezGALTimestampHandle ezGALCommandEncoder::InsertTimestamp ( )

Inserts a timestamp.

Returns: A handle to be passed into ezGALDevice::GetTimestampResult.

◆ SetBindGroup() [1/2]

void ezGALCommandEncoder::SetBindGroup	(	ezUInt32	uiBindGroup,
		const ezGALBindGroupCreationDescription &	bindGroup
	)

Sets a bind group to the given bind group index. Preferably, bindGroup should be created via ezBindGroupBuilder::CreateBindGroup.

This function binds a collection of resources (buffers, textures, samplers) to a specific bind group index. In debug builds, it performs extensive validation of each ezGALBindGroupItem against the layout's ezShaderResourceBinding to ensure:

General Validation:

Bind group layout matches the number of provided items
All resource handles are valid (non-null)

Buffer Validation:

Buffer handles are valid and match expected binding types
Constant buffers: No texel format override, zero offset, full buffer size
Structured/Texel/ByteAddress buffers: Proper usage flags, correct element alignment
Buffer ranges: Offset/size alignment with element boundaries, bounds checking
Access permissions: SRV/UAV flags match buffer usage flags

Texture Validation:

Texture handles are valid with proper view format compatibility
Array slice counts match binding requirements (e.g. 1 for non-arrays, multiple of 6 for cubes)
MSAA sample counts match between texture and binding
Access permissions: SRV/UAV flags match texture capabilities
Texture ranges: Mip levels and array slices within bounds
Make sure no proxy texture is present

Parameters

uiBindGroup	The bind group set index to set
bindGroup	Description containing the layout and resource items to bind

◆ SetBindGroup() [2/2]

void ezGALCommandEncoder::SetBindGroup	(	ezUInt32	uiBindGroup,
		ezGALBindGroupHandle	hBindGroup
	)

Sets a bind group resource to the given bind group index. As there are two functions to set bind groups (this one and the overload for transient bind groups) the last call takes precedence if both functions are called for the same index.

Parameters

uiBindGroup	The bind group set index to set
hBindGroup	Handle to the bind group that is to be used.

◆ SetIndexBuffer()

void ezGALCommandEncoder::SetIndexBuffer ( ezGALBufferHandle hIndexBuffer )

Todo:: Assert on index buffer type (if non nullptr)
