Thesis Update

Friday 29 January, 2010 · Thesis

It’s been a while since I made a post about my thesis so time to give you guys an update. Since many people probably forgot what my thesis is about, here’s a quick recap: Last semester I’ve been working on a technique to render realistic looking shadows for non-deformable objects in 3D scenes and this [...]

Compression, first tests looking good!

256 depth maps, 32 samples per pixel. Stanford Bunny Uncompressed Stanford Bunny Compressed Red areas indicate difference with the uncompressed version. In general I have less noise/self-shadowing, but some trivial points on the bunny are now miscalculated. It might have something to do with a special case where my current implementation of the compression algorithm [...]

CSM on CPU

Monday 23 November, 2009 · Computer Graphics · Thesis

Some screenshots of my current implementation on the CPU (uncompressed): Notice the banding of the shadows in the last picture. This is a consequence of using “only” 1024 shadow maps. With four times as much shadow maps there is a considerable improvement: Currently I’m still using an uncompressed version of the algorithm. Task for this [...]

Coherent Shadow Maps: Uncompressed Algorithm

Monday 16 November, 2009 · Computer Graphics · Thesis

Since it’s been a while since I made a blogpost, time to give an update on where I’m at and what I’ve been doing the past week. So currently I’m working on rendering soft shadows using my pregenerated shadow maps. No (decent) results yet, but it’s only a matter of hours before everything is up [...]
