| '''OpenGL extension ANGLE.framebuffer_multisample |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GLES2.ANGLE.framebuffer_multisample to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension extends the framebuffer object framework to |
| enable multisample rendering. |
| |
| The new operation RenderbufferStorageMultisampleANGLE() allocates |
| storage for a renderbuffer object that can be used as a multisample |
| buffer. A multisample render buffer image differs from a |
| single-sample render buffer image in that a multisample image has a |
| number of SAMPLES that is greater than zero. No method is provided |
| for creating multisample texture images. |
| |
| All of the framebuffer-attachable images attached to a framebuffer |
| object must have the same number of SAMPLES or else the framebuffer |
| object is not "framebuffer complete". If a framebuffer object with |
| multisample attachments is "framebuffer complete", then the |
| framebuffer object behaves as if SAMPLE_BUFFERS is one. |
| |
| The resolve operation is affected by calling |
| BlitFramebufferANGLE (provided by the ANGLE_framebuffer_blit |
| extension) where the source is a multisample application-created |
| framebuffer object and the destination is a single-sample |
| framebuffer object (either application-created or window-system |
| provided). |
