Rendering Threads

On my Linux box, it looks like the image renderer is using 8 threads. Is there a way to adjust that value up/down?

Not from the user interface. Otherwise, by program, you could add the row

  this.sunflow.parameter("threads", [i]numberOfThreads[/i]);

in the render method of com.eteks.sweethome3d.j3d.PhotoRenderer class.

Not sure how to rebuild the source on Linux ... maybe this can be a feature request for the PhotoRenderer in a future release?

Why not using the full power of the processor would be useful?

I noticed yesterday that my machine was totally swamped with java processes while doing photo rendering. Sometimes I want to do other tasks concurrently, so changing the number of render threads would be useful.

I didn't look at the code that closely, but does the photoRenderer automatically create a render thread for each processor on the system? So if I had a 16-processor machine, it would generate 16 render threads?
