Videomapping = processing 2 + aparapi (opencl) + shader

in Share your Work • 9 months ago

Recently I have shared some examples with aparapi library

https://forum.processing.org/topic/aparapi-opencl-directly-from-processing-java-grayscott-conways-examples-shared

I would like to show you my experiments with a videomapping. I've used processing 2, aparapi and displacement shader.

I hope you enjoy, thanks!!

Very nice to see the bricks come alive!

Is the mapping also handled by aparapi?

Hello Alexander, thanks!! :)

I´m using keystone library, and because my projection is near the wall normal, the existing bug is not affecting me.

Aparapi "only" calculates the Gray-Scott RD matrix (1024x768@60fps)

I´ve seen quasicinema and is a good tool, and a lot of work :P

Regards!

Could you share a little bit more in detail, how you did this ?

thanks clankill3r :)

knutl, the mapping was made with the Reaction-Difussion algorithm that toxis shares, in the examples you can see how to control Gray-Scott parameters in 2 dimensions.

For nice appearance I used a shader, is a displacement shader with light, you can see a lot of webgl examples like this

happy 2013!!
