Rigid body articulated human body models

Something like what you showed is easy for us when our offices reopen next week after our offices re-open on Friday (1/2).


In the meantime, here's a good tutorial you may not have found about creating avatars in Cal3D format:

Also, as mspusch suggests, if you download the trial product below and install it, you should find some .cfg files ready to use in Vizard that will look just like what you see above.

Sorry, a correction about cfg files in Live Characters. There are no cfg files to load a skeletal figure in Cal3D format within the Live Characters download. It does include fbx files that will load skeletons but those are to be used in Motionbuilder.

There is a way to export that to Cal3D from Max. As soon as our offices reopen and folks are back someone will be able to help with that.

thank you all.. i will wait for your help..

another question...
is there any chance to make the referentials of each body segment of the avatars visible?


Thanks again.

Hi Rfam,

It is easy to export a skeleton as an avatar, but the animations that come with the vcc_male avatar will not work with the export unless the original skeleton file is used. We can't give out the original skeleton file, but I'll check if it's alright to export a skeleton avatar for you that can use the animations.

To export a biped skeleton as an avatar within Max, select all the bones in the biped, go to Tools ----> Snapshot , then select Mesh as the snapshot type. just take one snapshot in the biped's base pose.

Next, select the root node of the new non-biped skeleton and attach all its children into one mesh. Be careful not to attach any parts of the actual biped since this can cause crashes.

Once it is all one mesh, add a Skin modifier and add all the bones from the biped, then adjusted the skinning as you wish.

Once that is done, you can follow the exporting steps in this tutorial:

Here is a sample script showing how to draw the skeletal structure of an avatar using on-the-fly points and lines:

import viz
viz.go()

def CreateSkeleton(avatar):
	
	points = []
	lines = []

	def traverse(bone):
		points.append(bone)
		for b in bone.getChildren():
			lines.append((bone,b))
			traverse(b)
			
	#Collect list of bones for drawing points and lines
	for b in avatar.getRootBoneList():
		traverse(b)

	#Create OTF object
	viz.startlayer(viz.LINES)
	viz.linewidth(2)
	viz.pointsize(6)
	viz.vertexcolor(viz.RED)

	for l in lines:
		viz.vertex(0,0,0)
		viz.vertex(0,0,0)

	viz.startlayer(viz.POINTS)

	for p in points:
		viz.vertex(0,0,0)

	skeleton = viz.endlayer()
	skeleton.dynamic()

	#Link each vertex to corresponding bone
	count = 0
	for b1,b2 in lines:
		viz.link(b1,skeleton.Vertex(count))
		count += 1
		viz.link(b2,skeleton.Vertex(count))
		count += 1

	for b in points:
		viz.link(b,skeleton.Vertex(count))
		count += 1

	return skeleton
	
model = viz.add('male.cfg',alpha=0.7)
model.state(2)

CreateSkeleton(model)

#Toggle avatar mesh on space key
vizact.onkeydown(' ',model.visible,viz.TOGGLE)

import vizcam
cam = vizcam.PivotNavigate(distance=3)
cam.centerNode(model)

thank you all for your attention...

and there is any option to make the referentials of each body segment visible in the vizard software?

thanks,
