Member Function Documentation

◆ IsEqual()

static bool Diligent::PipelineResourceLayoutDesc::IsEqual	(	const PipelineResourceLayoutDesc &	Desc1,
		const PipelineResourceLayoutDesc &	Desc2,
		bool	IgnoreVariables = false,
		bool	IgnoreSamplers = false )

inlinestatic

Returns true if two resource layout descriptions are equal, and false otherwise. Optionally ignores variable descriptions and/or sampler descriptions.

Member Data Documentation

◆ DefaultVariableMergeStages

SHADER_TYPE Diligent::PipelineResourceLayoutDesc::DefaultVariableMergeStages = SHADER_TYPE_UNKNOWN

Default shader variable merge stages.

By default, all variables not found in the Variables array define separate resources. For example, if there is resource "g_Texture" in the vertex and pixel shader stages, there will be two separate resources in both stages. This member defines shader stages in which default variables will be combined. For example, if DefaultVariableMergeStages == SHADER_TYPE_VERTEX | SHADER_TYPE_PIXEL, then both resources in the example above will be combined into a single one. If there is another "g_Texture" in geometry shader, it will be separate from combined vertex-pixel "g_Texture". This member has no effect on variables defined in Variables array.

◆ DefaultVariableType

SHADER_RESOURCE_VARIABLE_TYPE Diligent::PipelineResourceLayoutDesc::DefaultVariableType = SHADER_RESOURCE_VARIABLE_TYPE_STATIC

Default shader resource variable type.

This type will be used if shader variable description is not found in the Variables array or if Variables == nullptr

◆ Variables

const ShaderResourceVariableDesc* Diligent::PipelineResourceLayoutDesc::Variables = nullptr

Array of shader resource variable descriptions.

There may be multiple variables with the same name that use different shader stages, but the stages must not overlap.
