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.

Member Function Documentation

GetD3DMatrix() [1/2]

virtual D3DXMATRIX GetD3DMatrix ( TransformType  matType )

pure virtual

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

SetD3DMatrix() [1/2]

virtual void SetD3DMatrix ( const MCHAR *  paramName )

pure virtual

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.

SetD3DMatrix() [2/2]

virtual void SetD3DMatrix ( D3DXMATRIX  mat, TransformType  matType  )

pure virtual

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

GetD3DMatrix() [2/2]

virtual D3DXMATRIX GetD3DMatrix ( const 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
