Detailed Description

Abstract renderer geometry shader resource.

Member Enumeration Documentation

Input primitive type.

Enumerator:

InputPoints	List of point primitives
InputLines	List of line or line strip primitives
InputLinesAdjacency	List of line with adjacency or line strip with adjacency primitives
InputTriangles	List of triangle or triangle strip primitives
InputTrianglesAdjacency	List of triangle with adjacency or triangle strip with adjacency primitives

Output primitive type.

Enumerator:

OutputPoints	A list of of point primitives
OutputLines	A list of line primitives
OutputTriangles	A list of triangle primitives

virtual PLRENDERER_API PLRenderer::GeometryShader::~GeometryShader ( ) [virtual]

Destructor.

PLRENDERER_API PLRenderer::GeometryShader::GeometryShader ( Renderer & cRenderer ) [protected]

Constructor.

Parameters:

[in] cRenderer Owner renderer

virtual EInputPrimitiveType PLRenderer::GeometryShader::GetInputPrimitiveType ( ) const [pure virtual]

Returns the input primitive type.

virtual EOutputPrimitiveType PLRenderer::GeometryShader::GetOutputPrimitiveType ( ) const [pure virtual]

Returns the output primitive type.

virtual PLCore::uint32 PLRenderer::GeometryShader::GetNumOfOutputVertices ( ) const [pure virtual]

Returns the number of output vertices.

Returns:: The number of output vertices, 0 if the maximum possible number of output vertices should be used

virtual bool PLRenderer::GeometryShader::SetSourceCode	(	const PLCore::String &	sSourceCode,
		EInputPrimitiveType	nInputPrimitiveType,
		EOutputPrimitiveType	nOutputPrimitiveType,
		PLCore::uint32	nNumOfOutputVertices,
		const PLCore::String &	sProfile = `""`,
		const PLCore::String &	sArguments = `""`,
		const PLCore::String &	sEntry = `""`
	)		`[pure virtual]`

Sets the geometry shader source code.

Parameters:

[in]	sSourceCode	Geometry shader source code, usually blank ASCII code
[in]	nInputPrimitiveType	Input primitive type, for "Shader::SetSourceCode()" "InputTriangles" is used as default
[in]	nOutputPrimitiveType	Output primitive type, for "Shader::SetSourceCode()" "OutputTriangles" is used as default
[in]	nNumOfOutputVertices	Number of output vertices, 0 if the maximum possible number of output vertices should be used, for "Shader::SetSourceCode()" "0" is used as default
[in]	sProfile	Geometry shader profile to use, if empty string, a default profile will be used which usually tries to use the best available profile that runs on most hardware
[in]	sArguments	Optional shader compiler arguments, e.g. "version=150" when using Cg and a "glslg" profile
[in]	sEntry	Entry point, if empty string, "main" is used as default

Remarks:: Extended version of "Shader::SetSourceCode()" for geometry shaders allowing also to specify the input/output primitives and the number of generated vertices. Please note that not each internal implementation may actually need this information, but it's highly recommended to provide this information anyway to be able to switch the internal implementation (e.g. using OpenGL instead of DirectX and/or Cg instead of HLSL/GLSL).
