Texture mapping computer graphics apparatus includes an associating interpolator circuit for determining first interpolated opacity weighted colors and a first interpolated opacity in response to texture coordinates and texture colors and corresponding texture opacities, an associated color compositing circuit for a compositing the first interpolated opacity weighted colors and second interpolated opacity weighted colors to provide new opacity weighted colors, an associated opacity compositing circuit for compositing the first interpolated opacity and a second interpolated opacity to provide a new opacity, an unassociating circuit responsive to the new opacity weighted colors and the new opacity for providing unassociated colors, and a frame buffer for storing the unassociated new colors and the new opacity.
