Description | Hierarchy | Fields | Methods | Properties
## Unit CastleSceneCore ## Declaration `type TTrianglesShadowCastersList = class(TTriangle3SingleList)` ## Description Triangles array for shadow casting object. This guarantees that the whole array has first OpaqueCount opaque triangles, then the rest is transparent. The precise definition between "opaque" and "transparent" is done by TShape.Transparent. This is also used by OpenGL rendering to determine which shapes need blending. This separation into opaque and transparent parts (with OpaqueCount marking the border) is useful for shadow volumes algorithm, that must treat transparent shadow casters a little differently. ## Hierarchy TTrianglesShadowCastersList ## Overview ### Properties
| `property OpaqueCount: Cardinal read FOpaqueCount;`
## Description ### Properties
| `property OpaqueCount: Cardinal read FOpaqueCount;`
