Real-time Suggestive Contour Rendering

Realized I hadn’t posted this video yet: a couple of months ago, I took a break from the voxels and octrees to redo my Suggestive Contours GPU implementation. My shader-based approach combines the advantages of an object-space method in an image-based approach: It works for high-polycount models Real-time control over …

Suggestive Contours Code

The little download counter on my super secret world domination dashboard indicates that my thesis code implementations of rendering suggestive contours on 3d meshes has been downloaded over a hundred times. Which tickles my curiosity. If you’re doing anything fun, serious, silly (or can’t get the damn thing to work …

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 …

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, …

Random Contour Faces

I’ve been implementing an alternative CPU algorithm to draw contours last week. It was pitched by Markosian et. al, and I based my implementation on this Siggraph 2008 class by D. Decarlo. Instead of testing all faces of a mesh for contours, I only test a configurable amount of random …

Applying Suggestive Contours to …

In the second semester of this year, I’ll have to apply the suggestive contours algorithm I’ve implemented in an interesting way, in order to have some experimental results upon which I can base my thesis. A report on what I found out behind the cut.

Suggestive Contours tests

Having finished the basic implementation of contours and suggestive contours, I’m now implementing features like fading and suggestive highlights. I thought it would also be interesting to test my current implementation (and the effect of suggestive contours themselves) on some interesting test objects.¬† Findings behind the cut.

Suggestive Contours video

A new implementation of regular contours got rid of the noise I had in certain models with sharp edges (Stanford Dragon). Further optimization made it possible to record this demo: Now, I’m trying to find out why the suggestive contours ‘flicker’ in nearby viewpoints.
