[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.

Hi

The midterm goals for the GEGL-on-GPU GSoC project is to implement a few 
point ops as pixel shaders and to get GEGL to actually do processing on 
the GPU using these ops

Hi,

on July 6, the midterm evaluations open - and the mentors will have
until July 12 to evaluate the progress of their students, and decide
whether this is enough to

 - let them continue in GSoC
 - make Google pay the first half of the SoC stipends

Mentors and students, please do agree on the desired midterm goals for
your projects, and present them on the gegl-developer list.


Regards,
Michael

Eric Daoust's GSoC midterm deliverables:

 1) Sped up nohalo level 1 code.

 2) New fast resampling method targeted for downsampling (without
the affine transformation info passed from above, and
without variable size buffers, which will be implemented later
in the SoC). This will be the lower quality (but most likely
very fast) version.

(I'll email RE: Adam's deliverables when I have them nailed down.
Adam is currently focusing on the much trickier nohalo level 2 and
buffer issues.)
