I would like to create a 3D model that demonstrates the body movement captured by web camera. For example, when I raise my hand in front of the webcam, the 3D model also can raise his hand. Is it possible to do in Max?
Please help me!!! I would appreciate very much!

These are two very different things- if you just need the motion data you can use the cv.jit library which has many objects for this, such as cv.jit.centroids.

I already have the motion data, which object should I use to control the model’s motion using the motion data captured by webcam?
Thank you for your help!

1. break the model up into individual components and animate these components yourself OR export keyframe poses of the model. this requires exporting as an .obj and using jit.gl.model.

2. export the model data and animation data and create a vertex shader to do the skinning for you with jit.gl.mesh.

3. if on a mac and using 4.6 your best bet is to check out http://jitogre.org
if you go this route, i will do my best to help you out along the way (as i’m the creator of jit-ogre).

if not on mac or using 4.6, and want to use jit-ogre, then be aware that i’m *still* planning on porting this once i get some free time.

I will check out jit-ogre and think what I could do with that. Anyway, if I need any help with jit.ogre, how could I contact with you? Could I have your email? Thank you!

Could you please tell me how could I do with this? Actually, I am new with 3D stuff.
Thank you for your help

I was trying to figure out this patch.
its very close to what I am trying to do.
I found that the video is actually upside-down compared to the manipulated texture.
I cant figure how how to change it, or really anything about this patch at all.
can you explain this a little more, or direct me to the resources so that I can understand.
I have looked in every help file of every object but I am missing something.

thanks

Either way will
work. To flip the vertices, change snorm[1] to -snorm[1]. To flip
the tcs, change norm[1] to 1-norm[1]. Also you can change the scale
of the mesh to something like @scale 1 -1 1. Many ways to do this.
