Class TScissor

Unit

CastleRenderContext

Declaration

type TScissor = class(TObject)

Description

Scissor to clip displayed things, in addition to the global scissor affected by TRenderContext.ScissorEnable / TRenderContext.ScissorDisable. Always disable an enabled scissor (destructor does it automatically).

Make sure to enable and disable the scissor when the same OpenGL context is current. In practice, the only reliable way to do this is to enable and then disable the scissor within the same OnRender event.
