Render Target

From Wikipedia, the free encyclopedia

In the field of 3D computer graphics, a render target is a feature of modern graphics processing units (GPUs) that allows a 3D scene to be rendered to an intermediate memory buffer, or Render Target Texture (RTT), instead of the frame buffer or back buffer. This RTT can then be manipulated by pixel shaders in order to apply additional effects to the final image before displaying it.
