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.
Here’s the Stanford Dragon rendered using suggestive contours:
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.
Still needs filtering and optimization, but it’s a first step.
I thought it would be a nice experiment to log my progress on implementing suggestive contours for my thesis on a minute-by-minute basis. Whether this turns out to be an interesting log or a boring concatenation of my sloppy coding adventures, we’ll see. I might discover what’s eating the most …
Now works in every viewing direction. Up next: suggestive contours.
Time for a quick update. Last week, we decided to focus on the two papers which I found the most interesting: Suggestive Contours and Exaggerated Shading. It was time to cook up an OpenGL up to display contours, and later on suggestive contours. This implied I had to get started …
I’ve read some remaining papers about Non-Photorealistic Rendering. The first one was Image Analogies by A. Hertzmann from Microsoft Research. It describes a framework to process images, where the processing algorithm is derived from a given (set of) A and A’ images, where A is the original image and A’ …
