A class that enables render-to-texture by specifying textures and their attachment points.
A Framebuffer object contains a set of associations between rendering framebuffer attachment points and textures which are to be used for render-to-texture. This framebuffer object can then be used as a render target, where the output of rendering will be sent to the texture targets specified here rather than the main screen.

Create an empty framebuffer for the given context with no attached textures.
|
pure virtual |
Get the texture and texture face that is attached at the specified framebuffer attachment point.
If there is no attachment for that attachment point, the method has no effect and returns FALSE. Otherwise, the target texture and face are written to the output parameters and TRUE is returned.
Implemented in om::graphics::devices::opengl::OpenGLFramebuffer.
|
pure virtual |
Set the target texture for the specified framebuffer attachment point.
If the specified Texture is valid and supports the specified texture face, and if the specified attachment point is supported and valid, the texture is used as the target for the specified attachment point and TRUE is returned indicating success. Otherwise, FALSE is returned indicating failure, leaving the framebuffer unchanged.
Implemented in om::graphics::devices::opengl::OpenGLFramebuffer.

Remove all attached target textures from this framebuffer.
Implemented in om::graphics::devices::opengl::OpenGLFramebuffer.
Return the minimum size of the framebuffer in pixels along the specified dimension index.
This method finds the smallest size of the attached textures along the given dimension. Indices start from 0 and count to d-1 for a framebuffer with d dimensions. Since framebuffers are almost always 1D or 2D, dimension indices greater than 1 will result in a size of 1 being returned, since even a 1x1 framebuffer has a 3D depth of 1 pixel.
If there are no attached textures, 0 is returned.
