Master the basics of Gaussian Splatting! Plus some techniques for making it run faster and compress smaller. P.S. I know it's pronounced "Gawshian," but "Gaussian" just rolls off my tongue 😛
At 10:00 you talk about firing rays out from the camera to get pixel colour, but the whole point in “splatting” is that there is no ray firing happening. Instead 3D Gaussian are splatted onto the screen one after another from back to front until the view buffer is full. Did you make a mistake with your interpretation or did I misunderstand the way “splatting” works? Because I was quite sure that splatting is fundamentally not ray tracing. so there is no “firing a ray from the camera and checking intersections”
That was my understanding as well, where gaussian splatting mitigates the need for ray casting. But perhaps it is still used for some step in evaluating the pixel/density values, like you said, with a back to front pattern?
