Constructor & Destructor Documentation

Propane::FBOTextureRenderTarget::FBOTextureRenderTarget (  int  w, int  h )  [inline]

Create a texture, renderbuffer and depthbuffer, and start rendering to it. Instead of calling this directly, use getNewTextureRenderTarget to get the specific texture rendering target for your hardware. Any errors will be emitted to stderr. Parameters: w  The width of the window, in pixels h  The height of the window, in pixels

virtual Propane::FBOTextureRenderTarget::~FBOTextureRenderTarget (   )  [inline, virtual]

Basic destructor. MAKE SURE you have called end() before destructing, or your render target may disappear and you'll be left with an invisible window.

Member Function Documentation

virtual void Propane::FBOTextureRenderTarget::begin (   )  [inline, virtual]

Begin rendering to texture; every GL call after this one will render itself into the raw texture handle that we have retained. Implements Propane::TextureRenderTarget.

virtual void Propane::FBOTextureRenderTarget::end (   )  [inline, virtual]

Stop rendering to texture; after this call completes the texture should be updated with whatever calls we made since begin(). Implements Propane::TextureRenderTarget.

virtual GLuint* Propane::FBOTextureRenderTarget::getRenderTexture (   )  [inline, virtual]

Get the raw texture for later use Returns: A pointer to the raw texture, or NULL if the render failed. Implements Propane::TextureRenderTarget.
