psychopy.tools.gltools.attach(attachPoint, imageBuffer)[source]¶

Attach an image to a specified attachment point on the presently bound FBO.

:param attachPoint int: Attachment point for ‘imageBuffer’ (e.g. GL.GL_COLOR_ATTACHMENT0). :param imageBuffer: Framebuffer-attachable buffer descriptor. :type imageBuffer: TexImage2D or Renderbuffer

Examples

Attach an image to attachment points on the framebuffer:

GL.glBindFramebuffer(GL.GL_FRAMEBUFFER, fbo)
attach(GL.GL_COLOR_ATTACHMENT0, colorTex)
attach(GL.GL_DEPTH_STENCIL_ATTACHMENT, depthRb)
GL.glBindFramebuffer(GL.GL_FRAMEBUFFER, lastBoundFbo)

# same as above, but using a context manager
with useFBO(fbo):
    attach(GL.GL_COLOR_ATTACHMENT0, colorTex)
    attach(GL.GL_DEPTH_STENCIL_ATTACHMENT, depthRb)
