Interface ILspRenderTarget

All Known Implementing Classes:
TLspTextureRenderTarget
public interface ILspRenderTarget
An abstraction of a framebuffer into which rendering output can be directed. A render target can be the visible viewport of an ILspView or some offscreen buffer used for intermediate storage.

Since multiple render targets can be used in a nested way, the view keeps a stack on which clients can push a render target for use by calling push instead of calling bind on the render target directly. Calling pop subsequently unbinds the last pushed render target and rebinds the previously bound render target.

2012.0

  • Method Details

    • init

      void init(ILcdGLDrawable aGLDrawable)
      Initializes the render target.
      Parameters:
      aGLDrawable - the drawable for which the render target will be used

    • destroy

      void destroy(ILcdGLDrawable aGLDrawable)
      Destroys the render target.
      Parameters:
      aGLDrawable - the drawable for which the render target will be used

    • bind

      void bind(ILcdGLDrawable aGLDrawable)
      Binds the render target for use. This means that subsequent paints will be directed to this render target.

      This method should preferably not be used directly, since binding a render target automatically unbinds another possibly bound render target. Use the render target stack's push mechanism instead.

      Parameters:
      aGLDrawable - the drawable for which the render target will be used

    • unbind

      void unbind(ILcdGLDrawable aGLDrawable)
      Unbinds the render target. This means that subsequent paints will be directed to the main view.

      This method should preferably not be used directly, since unbinding a render target automatically binds the main view (the 0 frame buffer) as a render target, instead of the previously bound render target. Use the render target stack's pop mechanism instead.

      Parameters:
      aGLDrawable - the drawable for which the render target will be used
