Having passed the first hurdle and successfully managed to draw lines and rectangles (DH_GridX and DH_WideSafeX released yesterday) we move on to other things. In converting one of our FxScript filters, the aim is to write a filter that takes a 2 different areas from the input texture, copy those pixels to a buffer, then write the buffer back to a selected area of the the output texture.
What I'm confused about is whether we should be using
a) a new texture for the temporary buffer
b) a PBO with a renderbuffer
c) a PBO with a colorbuffer
thanks
