Neural material (de)compression – data-driven nonlinear dimensionality reduction
In this post I come back to something I didn’t expect coming back to – dimensionality reduction and compression for whole material texture sets (as opposed to single textures) – a significantly underexplored topic. In one of my past posts … Continue reading
Dimensionality reduction for image and texture set compression
In this blog post I am going to describe some of my past investigations on reducing the number of channels in textures / texture sets automatically and generally – without assuming anything about texture contents other than correspondence to some … Continue reading

White balance and physically based rendering pipelines. Part 2 – practical problems.
White balance and lighting conditions After this long introduction (be sure to check part one if you haven’t!), we can finally go to the problem that started whole idea for this post (as in my opinion it is unsolved problem – … Continue reading

White balance and physically based rendering pipelines. Part 1 – introduction.
This is part one of the whole article. Part two is here. In this two posts (started as one, but I had to split it to make it more… digestible) I’m going to talk a bit about the white balance. First … Continue reading
Siggraph 2014 talk slides are up!
As promised during my talk, I have just added Siggraph 2014 Advances in the Real-Time rendering slides, check them out at my Publications page. Some extra future ideas I didn’t manage to cover in time are in bonus slides section, … Continue reading
