I’m starting development on a project that requires a painterly look (think impressionist style like Van Gogh). I know that a big part of this style will come from the models and textures but a good shader is also key here. I found this really cool example of a brush stroke shader for real time rendering: Brush Strokes | GPU Hacks
Does anyone know if something like this could be done in Unity?
And to top it off, could this be made to work with oculus?
I don’t see any reason why something like this wouldn’t work in Unity. It would definitely be Pro only though as you’d need to render to texture for the post-processing passes.
It would be as much art as science getting it to look good, and I would experiment with a few different techniques and do some searching for published graphics papers. I might try, for example, encoding the stroke direction in the model (maybe using the vertex colour) rather than trying to extract it from edges. I would also try rendering the strokes with bump mapping and a simple lighting model to give the final image a bit of depth.
I have no had any experience with the Oculus, but once you have something rendering to your satisfaction, I don’t see why it wouldn’t work there. It is “simply” a matter of rendering the scene twice with different camera locations.
Thanks Shane! Looks like I have some research to do. I’ll look into rendered textures and see what I come up with.
Something very much like that was just released to the Asset Store.
Very recent release and of extremely high quality, i’ll link the tutorial here as it shows how great it is http://www.youtube.com/watch?v=y8Un83TQ6a4
It’s called painterly, strangely enough
