Re: Why I cannot get the specular reflection right with mesh

For the white dots: I had similar issues and then I discovered a lot of NaN and INF in the calculations (caused by the mesh imported I was using a the time).

Re: Path tracing in games

Why do everyone keep talking about path tracing? There is a wide range of algos with a different tradeoff between quality and speed. Couldn't a first step towards RT GI make use of one of them?

Re: Path tracing in games

In the end technologies like path-tracing may not be necessary at all for games I agree that it is amazing the quality reached by games nowadays and that there is still room for improvements. But what about reflections (wich are important for many surfaces)? In racing games you usually have the env...

Re: Path tracing in games

That's true, and yet sfx are starting to use RT and even GI instead of the old algos available at the time of JP. Isn't there a threshold (of quality requirements or scene complexity) above which is more convenient to leave rasterization in favour of other techniques? After all, even per pixel light...

Path tracing in games

I've just seen one of the latest video of the amazing path tracer developed by Jacco and I'm wondering: isn't path tracing possibly the worst (computationally-wise) rendering algorithm out there? Wouldn't other algos or even hybrid approaches (traditional RT with some sort of quick and dirty GI) be ...
