=====================================
This is a nerf gaussian splat renderer modeled after antimatter15's webgl implementation. You can create a splat from a video following instructions from a well written writeup from Alex Carlier here. You can read more about the creative process here.
Download this and drop it into openFrameworks/addons/ folder. Your point clouds go into the data folder in your project.
First you put your gaussian splat nerf PLY in the data folder, then declare an instance of an ofxSplat, ofxSplat splat in your header, say your point cloud is called pointcloud.ply then you call splat.setup("pointcloud.ply") to prepare the splats
Then in your update loop call splat.udate()
Then in your draw loop call splat.draw()
OF 10 and 11
Thanks to Zach Lieberman for writing the meat of the renderer, from the vbo, fixing the shaders, to the sorting and beyond.
