mosaic

Yesterday I mentioned using images as a source for the points and orientations. And I managed to do something.

First, the original image (a South Park version of myself, before I lose some weight):

And here's the various mosaic:

I used various effects to control the orientation in the cell. Plus I tried a random point selection, except for the first output.

Which one do you prefer ?

Naturally, to produce the output, I'm still using CUDA. I didn't used any data structure to optimize, so it can be computed a bit faster.

Yin Yang Texture

Here's a post on texture.

Previously, we were using a method to control images with points and normals. Alone, a point and a normal split the plane in two, a positive and negative part. But combined with other points and normals, we can actually control curve shapes. To visualize it, we assign white to the positive part and black for the other.

The textures proposed here are made by first splitting the plane in two parts. The two parts must be symmetrical just like the Yin Yang symbol.

We then distribute points and normals inside one of the part. We then reflect the point into the second part, but not the normal.

The method create a contrast and a perfect symmetry. Here's some results:

I won't describe the method to render those images because it's very complex. Also, the process is very slow. Unlike the live-wallpaper I'm working on, or the previous images I showed, we cannot compute those in real-time.

Unfortunately, we haven't implement this with CUDA. With CUDA, it wouldn't be in real-time, but it would be much faster. Specially the per-pixel rendering part. Let me know what you think about these Yin-Yang images.
