- Description
The ShadeCaps property indicate the shading operations that the device is capable of performing.
The described effect applies when the flag is set.
Flat shade mode uses the specular and color component of the first vertex in a triangle to shade the whole face.
Gouraud shade mode interpolates the color and intensity of adjacent vertices across the space that separates them in a linear fashion.
Phong shade mode calculates the appropriate shade value for each pixel but is not yet supported in DirectX.
Monochrome shading modes use the specular component's blue channel for the white intensity.
Any commands the device supports are assumed to also support the flat shading mode.
When a mode doesn't support alpha components, alpha is interpreted as being at maximum intensity (255).
The color, specular highlights, fog, and alpha interpolants of a triangle each have capability flags that an application can use to find out how they are implemented by the device driver. These are modified by the shading mode, color model, and whether the alpha component of a color is blended or stippled.
