**Working with Framebuffer Objects (FBOs):**
Creating an empty framebuffer with no attachments::
fbo = createFBO() # invalid until attachments are added
Create a render target with multiple color texture attachments::
colorTex = createTexImage2D(1024,1024) # empty texture
depthRb = createRenderbuffer(800,600,internalFormat=GL.GL_DEPTH24_STENCIL8)
GL.glBindFramebuffer(GL.GL_FRAMEBUFFER, fbo.id)
attach(GL.GL_COLOR_ATTACHMENT0, colorTex)
attach(GL.GL_DEPTH_ATTACHMENT, depthRb)
attach(GL.GL_STENCIL_ATTACHMENT, depthRb)
# or attach(GL.GL_DEPTH_STENCIL_ATTACHMENT, depthRb)
GL.glBindFramebuffer(GL.GL_FRAMEBUFFER, 0)
Attach FBO images using a context. This automatically returns to the previous
FBO binding state when complete. This is useful if you don't know the current
binding state::
with useFBO(fbo):
attach(GL.GL_COLOR_ATTACHMENT0, colorTex)
attach(GL.GL_DEPTH_ATTACHMENT, depthRb)
attach(GL.GL_STENCIL_ATTACHMENT, depthRb)
How to set userData some custom function might access::
fbo.userData['flags'] = ['left_eye', 'clear_before_use']
Binding an FBO for drawing/reading::
GL.glBindFramebuffer(GL.GL_FRAMEBUFFER, fb.id)
Depth-only framebuffers are valid, sometimes need for generating shadows::
depthTex = createTexImage2D(800, 600,
internalFormat=GL.GL_DEPTH_COMPONENT24,
pixelFormat=GL.GL_DEPTH_COMPONENT)
fbo = createFBO([(GL.GL_DEPTH_ATTACHMENT, depthTex)])
Deleting a framebuffer when done with it. This invalidates the framebuffer's ID
and makes it available for use::
deleteFBO(fbo)
