Hi Lukas,
Your explanation is a good one. Didn't come up to write it down that way.
The issue with memory during compositing is the way the nodes-editor
works. When changing a node-value (like degree) only the rotate-node and
all dependent nodes are re-calculated. The input-image is not
re-calc

Surely you just need an OpenCL library present? It would be like falling
back on Mesa if hardware GL is not available: the li

This depends on the implementation. OpenCL code
I have tried out your patch, nice work :)
Here are some more thoughts on how to process data in the node tree. I
hope i'm not getting too verbose or tell you guys obvious stuff ;)
Basically when talking about data in the tree i see two different
types of dependency:

Hi,
I have done a proof of concept on Blender and OpenCL. My victim is the
compositing node system. I learned a lot during these 4 hours and put it
on my website including the patch.
http://sicg.atmind.nl/index.php?option=com_content&view=article&id=21:blender-compositor-and-opencl&catid=8:blen
any how, all this sounds good to my ears !
if it gets implemented for nodes (especially compositing), count me for
testing :)

I started playing with it recently and I consider that my knowledge on this
area is still small but I will follow your discussion very closely.
I also want to make some observations to what has already been said. Most o

Thanks, but I have a question on MiniCL as I am not sure if this is
suitable. IMO you need different code for CPU's and GPU's.
CPU
You may have noticed the new simulation nodes i am currently working
on ( http://phonybone.planetblender.org/ ). Until now i didn't really
pay attention to OpenCL, in fact i even made my own multithreaded
batch processing system for object data like vertices and particles.
Yesterday i took a closer
Hi,
this is a very good idea and it would be awesome to have OpenCL for
Fluids in Blender!

You might be interested in MiniCL used in the bullet physics library.
It permit to use OpenCL on CPU only.

Hi Jeroen,
I have been experimenting with OpenCL in Blender, trying to add an
accelerated particle system to the BGE.
I've been keeping track of my progress on my blog: http://enja.org
I have some code up on github:

and a fork of Blender with some modificati

Hi all
I have been experimenting with OpenCL and are planning a basic framework
to support it in Blender.
main features are:
* OpenCL is disabled by default, CPU fall-back must ALWAYS be
available. OpenCL can be enabled with command-line parameter
* Compiler directive to completely disable
