Swallowing the elephant...
matt pharr, of pbrt fame, recently did a series of blog posts on getting a scene from moana to run and render over pbrt3. while this isn't as much cgi news, it would be neat to convert a production ready scene to luxcore and see if we can render it.
the scene is somewhere between 50-70gb when loaded into memory. I'm sure it will be different for us with a different system, but a hefty scene would be a nice stress test on the CPU part of the engine at least.

Woah this is even better than I hoped for when I saw the "Noise" in the title!Dade wrote: ↑Thu Jun 28, 2018 9:07 am High-Performance Procedural Noise using an Histogram-Preserving Blending Operator: https://eheitzresearch.wordpress.com/722-2/ (this could be extremely useful for GPUs)
Auto-tiling of image maps - very cool. And the triplanar blending at the end is also super useful.

That one is very cool.

Re: CGI tech news box
This is not really CGI news, but might be useful anyway:
double-conversion is a library that can convert strings to floating point and vice versa roughly twice as fast as strtof().
I found it mentioned here: https://pharr.org/matt/blog/2018/08/03/ ... -mail.html
I remember that we had problems with the standard C++ floating point parsing with PySide/pyinstaller on Linux - this library may be able to fix that, too.

Re: CGI tech news box
pbrt-v3 actually uses this in its triangle mesh intersection code, if you wanted to take a look at some code already using thisB.Y.O.B. wrote: ↑Sat Aug 25, 2018 1:27 pm Sorry if this is old news, it's from 2013:
