Reference TShadowBuffer

Declared in Codebot.Render.Buffers.pas on line 49

TShadowBuffer records depth into a square depth texture for shadow mapping. The texture compares depths when sampled, so shaders read it using a sampler2DShadow which returns how lit a point is from 0 to 1 with filtered edges. Points outside the texture are lit.

  TShadowBuffer = class(TContextManagedObject)
  public
    { Create a shadow buffer using a size in pixels }
    constructor Create(Size: Integer = 2048);
    destructor Destroy; override;
    { Start recording depth. Nothing is drawn to color, and depths are offset
      slightly to prevent surfaces from shadowing themselves. }
    procedure StartRecording;
    { Stop recording, restoring the prior frame buffer and viewport }
    procedure StopRecording;
    { The depth texture }
    property Texture: Integer read FTexture;
    { The width and height of the depth texture in pixels }
    property Size: Integer read FSize;
  end;
