[Bf-cycles] Bf-cycles Digest, Vol 56, Issue 13

Wed Dec 23 11:38:32 CET 2015

Hello Sergey, nice to meet you (sort of!) :).

Hmmm, I don't have any diagrams or code I can show you right now I'm
afraid. However, I can describe what the api does more or less if that
would help? The addon started life as just that, an addon, but the we
realised that we couldn't justify writing a whole new render engine. So we
are now focussing on turning our code into an api that can be used to
distribute and accelerate different tasks.

So that is what our planned api does, takes data from a client machine and
then distributes it in real time to a number of nodes which then perform a
commanded task (such as rendering the scene in this case) and then combine
and return the results.

However it is planned that the 'data' and 'task' I speak of can be generic,
at least to a point. For example, I'm currently talking to a researcher in
Portugal (specialist in fluid simulation and also part of Problender, the
Portuguese Blender assoc)  about how I could accelerate the Blender physics
engine using our same api.

Essentially what we have built and will continue to build is a method by
which data can be streamed out to nodes on a network in real time, and then
the results of some process that acts on that data, streamed back again.

As the prototype clearly shows, we have done a crude version of this and we
chose the cycles render engine as a particular use case.

Why I am wanting to work more closely with the cycles group is that at the
moment I am finding it time consuming to integrate with cycles from the
'outside'. Essentially I am doing two tasks, developing our API and at the
same time, attempting to integrate it with cycles. I am fast realising that
it might be better to work with you all on the integration part. I am still
happy to do that work, but I need to ask a lot of questions about the best
way to do it.

So that is my proposal, I am happy to share my progress and any information
necessary for others to understand what I am doing with the group if I
might be allowed to ask about how certain things are done.

One example of this is the node editor, with cycles and blender internal,
the node editor will display the material node tree, but not when I enable
my addon and use it as a 'render engine'. It seems that Blender does not
recognise my addon as being able to support the ShaderNodeTree tree-type
and so won't display the material node-tree.

I could spend a lot more time trying to figure this out by trial and error
and hacking, but this seems inefficient when I could reach out and
collaborate.

Kind Regards

James :)
