That's good. So you could combine it with head-tracking and have an interactive 3D piece of "growing" art on your wall. I'm guessing the GPU on a Raspberry Pi, for example, would be underpowered but it would be fun to look into.
- fenomas 12y agoWell, rendering data that's already made is very light weight, since it's only a few hundred triangles. As for creating new projections, it depends on whether you can read data from the gpu with gl.readPixels() or not. From googling docs I thought this would work anywhere OpenGLES 2.0 was supported, but my test device claims to support OpenGLES 3, and readPixels() fails on it - I haven't looked closely at why yet.
- tagawa 12y agoThanks. I don't have a Raspberry Pi or similar (yet) but I might look into the head-tracking part.
