[Gegl-developer] [GSoC] Midterm project evaluations coming up

[Nicolas Robidoux]

Adam Turcotte's midterm deliverables:

-- Figure out how to use/adapt/emulate intermediate buffers to store
   intermediate results (kind of like nohalo runs on the GPU:
   intermediate buffer would be like a texture).

-- Figure out how to use/adapt/emulate variable size sampler buffers
   for non-recursive reasonable quality downsampling.

-- Make good progress in implementing the above (hopefully, be done)

[Gegl-developer] [GSoC] Midterm project evaluations coming up

[Nicolas Robidoux]

Argh!

My explanation (RE: Adam's GSoC deliverables) was terrible (Adam just
called me on it).

What I meant:

Somehow allowing a variable footprint (stencil) in (re)samplers. Right
now, the footprint is fixed (from
gegl/gegl/buffer/gegl-sampler-cubic.c):

 GEGL_SAMPLER (self)-context_rect.x = -1;
 GEGL_SAMPLER (self)-context_rect.y = -1;
 GEGL_SAMPLER (self)-context_rect.width = 4;
 GEGL_SAMPLER (self)-context_rect.height = 4;

The RHS's are arbitrary, but I don't think they can be changed at
run-time on a pixel by pixel basis (or even on a run by run basis?).

Hopefully, it makes sense now.

We already have some ideas of how to emulate it.
