This is used with lookup tables for reflection components (Reflection R|Reflection G|Reflection B|Distribution 0|Distribution 1|Fresnel).
Hardware limitations affect the values that can be taken on by various attributes.
See documentation on basic graphics.
This element takes <ReferenceLookupTableCtr> (representing a lookup table) and <NullLookupTableCtr> (when there are no settings) as children.
Value | Description |
CosNormalHalf | The cosine of the angle formed from the normal and the half vector. |
---|
CosViewHalf | The cosine value of the angle formed from the normal vector and the half vector. |
---|
CosNormalView | The cosine value of the angle formed from the normal and the view vector. |
---|
CosLightNormal | The cosine value of the angle formed from the light vector and the normal. |
---|
CosLightSpot | The cosine value of the angle formed from the light vector and the spot direction vector. |
---|
CosPhi | The cosine value of the angle formed from the half vector's tangent projection vector and the tangent vector. |
