Ambient Lighting State

Ambient Lighting State (Direct3D 9)

Ambient light is surrounding light that radiates from all directions. For information about how Direct3D uses ambient light, see Mathematics of Lighting (Direct3D 9).

A C++ application sets the color of ambient lighting by invoking the IDirect3DDevice9::SetRenderState method and passing the enumerated value D3DRS_AMBIENT as the first parameter. The second parameter is a color value. The default value is zero.



// This code example assumes that d3dDevice is a
// valid pointer to an IDirect3DDevice9 interface.

// Set the ambient light.

d3dDevice->SetRenderState(D3DRS_AMBIENT, 0x00202020);
