Making Bump (normal) Maps for use with jit.gl.material


    Jan 12 2012 | 1:01 am
    The patch below takes a greyscale image and (using jit.gl.pix) converts it to a normalmap for really cool looking 3D lighting tricks. Bump mapping is typically used to make a low-poly 3D object look more complex by tricking the lighting calculation. You can use jit.gl.slab.gauss6x to smooth out the bumps if you like.
    Enjoy!

      Hi Andrew
      this looks like a cool patch... but when I open the grabber, I only get a black videoplane on my macBookPro i7, GT 330M, os X.7.2, Max 6.0.3 51824
      Am I missing something ?

      I get a black videoplane too :(

      same here, there is an apparent error in jit.gl.pix saying that the concat class does not work in gen domain jit.gen

      I edited the original patch, so it hopefully should work now. Let me know how that works for you.

      I see a black videoplane again, how can I help you? There are no error message in the Max window.

      Hi @micron, what hardware are you using? Do other jit.gl.material or jit.gl.pix examples work on this computer? What version of Max?

      still same problem here : black video plane) jit.gl.material and jit.gl.pix works fine on this computer.

      MacBook Pro 2.4 Ghz Intel Core i5 NVIDIA GeForce GT 330M 256 MB 4 GB RAM OS X Lion 10.7.2 Max 6.0.3 51824
      Examples works great.

      OK, I think it's the jit.gl.videoplane that's causing trouble. Switching it out for jit.gl.gridshape should help:
      Let me know how that works.

      Works fine now and it's a very nice patch :)

      If you happen to have a Kinect camera lying around, the depth map works pretty nicely with this patch too.

      @llumen What version of Max are you using? [concat] is new as of 6.0.3
