Vocabularygpu.buffersClass descriptionbuffer-kind values tell the graphics driver what the primary application of a
buffer object will be. Note that any buffer can be used for any purpose; however, performance may be improved if a buffer object is constructed as the same kind as its primary use case.
| • | A vertex-buffer is used to store vertex attribute data to be rendered as part of a vertex array. |
| • | An index-buffer is used to store indexes into a vertex array. |
| • | A pixel-unpack-buffer is used as a source for updating texture image data. |
| • | A pixel-pack-buffer is used as a destination for reading texture or framebuffer image data. |
| • | A transform-feedback-buffer is used as a destination for transform feedback output from a vertex shader. |
NotesThe
pixel-unpack-buffer and
pixel-pack-buffer kinds require OpenGL 2.1 or the
GL_ARB_pixel_buffer_object extension.
