virtual bool iShader::ActivatePass	(	size_t	ticket,
		size_t	number
	)			[pure virtual]

Activate a pass for rendering.

virtual bool iShader::DeactivatePass

(

size_t

ticket

)

[pure virtual]

Completly deactivate a pass.

virtual const char* iShader::GetFileName

(

)

[pure virtual]

Get name of the File where it was loaded from.

virtual const csShaderMetadata& iShader::GetMetadata

(

size_t

ticket

)

const [pure virtual]

Get shader metadata.

virtual size_t iShader::GetNumberOfPasses

(

size_t

ticket

)

[pure virtual]

Get number of passes this shader have.

virtual size_t iShader::GetTicket	(	const csRenderMeshModes &	modes,
		const iShaderVarStack *	stacks
	)			[pure virtual]

Query a "shader ticket".

Internally, a shader may choose one of several actual techniques or variants at runtime. However, the variant has to be known in order to determine the number of passes or to do pass preparation. As the decision what variant is to be used is made based on the mesh modes and the shader vars used for rendering, those have to be provided to get the actual variant, which is then identified by the "ticket".

virtual iObject* iShader::QueryObject

(

)

[pure virtual]

Query the object.

virtual void iShader::SetFileName

(

const char *

filename

)

[pure virtual]

Set name of the File where it was loaded from.

virtual bool iShader::SetupPass	(	size_t	ticket,
		const csRenderMesh *	mesh,
		csRenderMeshModes &	modes,
		const iShaderVarStack *	stacks
	)			[pure virtual]

Setup a pass.

virtual bool iShader::TeardownPass

(

size_t

ticket

)

[pure virtual]

Tear down current state, and prepare for a new mesh (for which SetupPass is called).
