This is a recent webcam experiment. I use a GLSL shader to deform the sphere with the webcam image in realtime. The Lighting is also done in the shader.

PS: Do you see me putting a finger in my nose? Nasty!

thats pretty awesome, didn't know GLSL shaders could deform shapes like that...

i swear, i was planning to do _exactly_ the same thing!

anyways; good work dude!

very nice! i'll enjoy seeing how this evolves.

This is nice. I did some work on several similar things using Quartz Composer and GLSL shaders a while back. One thing I never managed to do properly is generate normals for the distorted vertices. Just wondering if you managed to crack this...

Well as far as I can tell they should be incorrect since the normals should be based upon the unmodified vertices depending on what I read about it. The lighting seems to be correct though which indicates that the might be correct. So I am not really sure which is the case right now since this is just a quick sketch.
toneburst 1 year ago

Oh, OK. So you didn't try to modify the normals to take account of the displacement.

If you're interested, it is possible to do this using normal maps, generated from the displacement image. I'm not sure how to apply this to a sphere shape though..

Really funny experiment.
Lee Byron 1 year ago

Wow! That's really cool! Got any nice resources to point to for getting started with GLSL?

I would suggest checking out the orange book. It made alot of things clear for me about how shaders work and allready has some really great shader examples!
