Found it in the source code. It's a flattened list, i.e. python list of 16 floats.

What is the data type of the parameter transform for the function DefineMesh()? I.e., how do I create it?

As I wrote, there was this mistake in a intermediate version of the test code. But the problem was and is WaitForDone(), which does not return.

I'm quite sure that there is a bug as the same configuration works fine with a HasDone() loop.

HasDone works with both engines. There was a problem with the break condition in my latest code. Still I guess that the is something wrong with WaitForDone().

I'm going to try TILEPATH. But still the behavior of haltspp is strange. Now with HasDone(): def render(scene): session = build_session(scene) session.Start() while True: sleep(1) session.UpdateStats() stats = session.GetStats() print("[Elapsed time: %3d/5sec][Samples %4d][Avg. samples/sec % 3....

Just found out: returns immediately, not at all.

Of course I don't need the loop. This is just for the time restricted approach. But that's not the issue. It should print the stats after returning from WaitForDone(), and then break anyway if more the 5 secs past.

But it hangs (processing) before reaching the print.

def render(scene): session = build_session(scene) session.Start() startTime = time() while True: session.WaitForDone() #sleep(1) elapsedTime = time() - startTime session.UpdateStats() stats = session.GetStats() print("[Elapsed time: %3d/5sec][Samples %4d][Avg. samples/sec % 3.2fM on %.1fK tris...

How can I regulate sun and sky2 power to match real world radiation at a certain longitude, latitude, altitude at specific time of day and year, at clear weather condition?

I can calculate the radiation in watts per square meter. How do I translate this in LuxCore parameter?

I need to compare the irradiation between scenes with different sets of lenses. Tracing performance will be impacted by differences of the scenes, and external factors like e.g. system load. So I cannot expect that a fixed tracing duration would deliver comparable results. How can a best achieve tha...
