fun and play with particles in Finished Work Posted February 9 having some fun with particles.... birth of a massive star. for my little #astrophysics exploration, i’ve created a star simulation using openCL in houdini. its based on nbody #physics model, only driven by #gravity. using #nvidia #quadro rtx 5000 #arnoldrender. the colours are not quite right, I am trying to integrate kelvin colour temperature. the current colour is based on density and speed. In this simulation, I assumed 48% amount of negative gravity to fill the mystery of dark matter. I used 1 million nbodies for the simulation. for the steps, I am planning to add finer particle streams to get more details. fast particle rendering with path tracer is hard !
