Nuclear Dawn New Trailer

A new trailer for mod-project-gone-pro Nuclear Dawn was released yesterday. I’m glad to see a project I’ve worked on for 2 years coming close to release. Nice how they seem to have nailed the RTS overview and node structure system, all running on the Source engine. All the best & …

Thesis text and code

I’ve bundled my thesis implementations and put them up for download on the thesis code page. The thesis text (and a small overview) can be downloaded from the thesis page itself. I’d like to thank my promotor, suprvisors and readers for all their efforts, and hope my work and code …

Structure From Motion Update

This is one of the latest results of our Capita Selecta project (Selected Heads. Hah, the things I do with language …), in which we try to reconstruct human faces using Structure From Motion techniques. I refer to the previous posts about this subject for technical details, but in short: …

Sin() City

Some images I rendered for my thesis text yesterday. Left: just toon shader. Right: toon shader + suggestive contours + suggestive highlights, an attempt at a Frank Miller-like rendering style. All of this is rendered at min. 24 frames/second at a resolution of 760 x 760.

Contour and Valley detection using GLSL

Today, I managed to perform contour/suggestive contour rendering in imagespace – thus working on a rendered diffuse shaded image. After using the Sobel edge detection filter  to detect regular contours, I looked for an efficient algorithm to detect valleys and creases, in order to draw suggestive contours as well. As …

Structure From Motion

For our Capita Selecta project – a freeform 2-semester project with prof. P. Dutré and prof. E.Duval – we decided to build something around Structure From Motion. This involves starting from photographs of an object/environment and ending up with a fully textured 3d mesh – a nontrivial task. Tech babble …

Markosian Suggestive Contours

I’ve implemented the pick-some-random-faces-algorithm (the algorithm formerly known as the Markosian algorithm, from this paper) for suggestive contours too now. Results are a bit better when it comes to framerate, with the big gains of course in models with more faces. For example, of the 40000 faces of the skull, …

Image Space Oddity

I’ve been trying to work out a good CPU-accelerated version the my suggestive contours algorithm during the last few weeks, and after working through some technical difficulties, I managed to compute and draw regular contour lines this afternoon: Hard to see? I know,  it looks craptastic. But after an afternoon …
