NAME
cgD3D9SetUniformMatrixArray - set the elements for an array of uniform matrix parametersSYNOPSIS
#include <Cg/cgD3D9.h>
HRESULT cgD3D9SetUniformMatrixArray( CGparameter param, DWORD offset, DWORD numItems, const D3DMATRIX * matrices );
PARAMETERS
- param
- The parameter whose array elements are to be set. It must be a uniform matrix parameter.
- offset
- The offset at which to start setting array elements.
- numItems
- The number of array elements to set.
- matrices
- An array of matrices to set for param. The upper-left portion of each matrix is extracted to fit the size of the input parameter. numItems matrices are expected to be passed to the function.
RETURN VALUES
Returns D3D_OK if the function succeeds.Returns the D3D failure code if the function fails due to a D3D call.
DESCRIPTION
cgD3D9SetUniformMatrixArray sets the elements for an array of uniform matrix parameters.EXAMPLES
// matrixParam is a CGparameter handle of type float3x2 // arrayParam is a CGparameter handle of type float4x4[4] ... // intialize the data for each parameter D3DXMATRIX matTexTransform( 0.5f,0, 0,0, 0 ,0.5f, 0,0, 0.5f,0.5f, 0,0, 0 ,0, 0,0 ); D3DXMATRIX matRot[2]; D3DXMatrixRotationAxis(&matRot[0], &D3DXVECTOR3(0,0,1), D3DX_PI*0.5f); D3DXMatrixRotationAxis(&matRot[1], &D3DXVECTOR3(0,1,0), D3DX_PI*0.5f); ... // only use the upper-left portion. // non-arrays can be set, but only when offset=0 and numItems=1. cgD3D9SetUniformArray(matrixParam, &matTexTransform, 0, 1); // set the 3rd and 4th elements of the array cgD3D9SetUniformArray(arrayParam, matRot, 2, 2);
ERRORS
cgD3D9Failed is generated if a D3D function returns an error.CGD3D9ERR_NODEVICE is returned if a required D3D device is NULL. This usually occurs when an expanded interface routine is called but a D3D device has not been set with cgD3D9SetDevice.
CGD3D9ERR_NOTLOADED is returned if program was not loaded with the cgD3D9LoadProgram.
CGD3D9ERR_NOTMATRIX is returned if param is not a matrix.
CGD3D9ERR_NOTUNIFORM is returned if param is not a uniform parameter.
CGD3D9ERR_NULLVALUE is returned if matrices is NULL.
CGD3D9ERR_OUTOFRANGE is returned if offset plus numItems is out of the range of param.
CGD3D9ERR_INVALIDPARAM is returned if the parameter fails to set for any other reason.
