mul

Multiplies the components of two source registers. The result is dest = src0 * src1.

mul dest, src0, src1

Example

// This example combines the texture color and the diffuse color.

// The shader is shown below.
ps.1.0              // Version instruction
tex t0              // Declare texture.
mul r0, v0, t0      // Multiply diffuse color with gradient texture.


// The following images show the contents of the source registers the 
// resulting output register. 
// Where src1 is white, the destination pixel color is the same as the 
// source pixel color since dest = src * 1.0. 
// Where src1 is black, the destination is also black. 
// The pixel colors in the middle of the destination image are a blend 
// of src0 and src1.

// Additional code loads a texture in texture stage 0.
LPDIRECT3DDEVICE8   m_pd3dDevice;   // Init this device pointer in the application.
LPDIRECT3DTEXTURE8  m_pTexture0;    // Use this variable to hold a pointer to the texture.
TCHAR               strPath[512] = "textureFile.jpg";

D3DUtil_CreateTexture( m_pd3dDevice, strPath, &m;_pTexture0, D3DFMT_R5G6B5 );
m_pd3dDevice->SetTexture( 0, m_pTexture0 );
