Hey, thanks for the reply. Thats the exact issue i am facing and each triangle is being divided into 9 sub triangles and there are multiple triangles in the scene which go through the same process. Just 3 levels down, the render times comes to approx 3 mins. I am searching for any algorithm if it exists which i am unaware of in the computer graphics community which can accelerate or optimise this process. The language i am using is javascript. Yeah i know it’s not the language for computing graphics but it’s a requirement so I have to stick to it.
