Detailed Description

An interface to allow access to scene transforms.

This is important as depending on the pass different transforms may be required. Using this system makes sure the correct transform is used.

Get the current matrix.

Get the Scene based Transforms such as View and Projection, this shouldn't be used for world matrix info

Parameters:

matType

The matrix to receive

Returns:

A D3D Matrix

Set the current Matrix.

Set the Projection and View Matrix for the parameter supplied. This currently only supports lights

Parameters:

paramName

A pointer to a string containing the name as defined in the effect file.

Set the currentMatrix.

Allows a developer to store Projection and View matrix data. This will be typically used to store effect specific matrices used in environmental rendering. An example would be cube map generation. The developer needs to make sure the data is up to date for when the shaders require this. Ideally this would set in a PreRender method.

Parameters:

mat	The matrix to store
matType	The type of matrix to store

virtual D3DXMATRIX GetD3DMatrix	(	MCHAR *	paramName,
		TransformType	matType
	)		[pure virtual]

Get the current matrix.

Returns the matrix for the specified parameter

Parameters:

paramName	A pointer to a string containing the name as defined in the effect file
matType	The transform to obtain

Returns:

A D3D Matrix
