UPDATE APRIL 12, 2021<\/h2>\n

Reviewed WebGL and blog pages. Standalone version is now running under Unity 2021 and should be ready for release quite soon.

\nPCSB can now export interesting point clouds into Houdini (or other softwares) to do some nice renderings.
\nYou can test the limited version of the export feature by yourself, right here (one frame only):<\/p>\n

Why a Desktop version?<\/strong>
\nI wanted to be able to export PLY sequences at high framerate to get it animated in Houdini.
\nI managed to do it from the browser but I quickly run into memory problems and browser limitations. I was only able to get short sequences with a very low framerate.<\/p>\n

That’s why I decided to port all this native OpenGL 2.x code to Unity and take profit from the power of DirectX11 and compute shaders. I still have a lot to do but I can now record very large sequences with a decent framerate… and export it very quickly on the hard drive.<\/p>\n
