An extension trait that includes framebuffer-related OpenGL methods.

Provided Methods

Create a new framebuffer object with no attachments.

Safety

Most OpenGL function calls assume a framebuffer object will be framebuffer-complete. Since the new framebuffer will have no attachments, it will not be framebuffer-complete. Violating this invariant is considered undefined behavior in glitter.

See also

gl.build_framebuffer: A safe wrapper for building a framebuffer, which ensures framebuffer-completeness.

gl.check_framebuffer_status: Checks to see if a framebuffer object is framebuffer-complete.

glGenFramebuffers OpenGL docs

Returns the status of any framebuffer-completeness errors of a currently-bound framebuffer object. Returns None if the framebuffer is framebuffer-complete.

glCheckFramebufferStatus OpenGL docs

Attach a renderbuffer object to a framebuffer object's attachment point.

  • gl_fbo: The binding of the framebuffer to attach to.
  • attachment: Which attachment point of the framebuffer to attach to.
  • renderbuffer: The renderbuffer to attach.

See also

glFramebufferRenderbuffer OpenGL docs

Attach a texture to a framebuffer object's attachment point.

  • gl_fbo: The binding of the framebuffer to attach to.
  • attachment: Which attachment point of the framebuffer to attach to.
  • tex_target: The 2D 'face' of the texture to attach.
  • texture: The texture to attach.
  • level: The mipmap level of the texture to attach. Note that this value must be 0.

Panics

This function will panic with a debug assertion if level is not 0.

glFramebufferTexture2D OpenGL docs

Clear the currently-bound drawing buffers that are specified by the buffers argument.
