How to get the coordinates of bone's head and tail

Hi, everyone, I want to use IK in my app, but it is not support in blend4web. So I try to design algorithm to solve the Inverse Kinematics. And to solve it, I need to know the bones coordinates.

Look forward to Look forward to your reply.

Hi berdon,
This might help:
get_bone_tsr(armobj, bone_name, dest)
Or,
get_bone_tsr_rel(armobj, bone_name, dest)

You also have the set_bone functions on this page.

Hi, Will, thank you very much, then I can use the angel and the length of bone to calculate the bones coordinates.
Then, I want to know whether the IK will be supported in B4W.

It is probably only a matter of time. You know you can bake your IK animations? But is sounds like you want real time procedural movements. I want that for VR so your virtual arms sort of follow what the hands are doing. I have seen it in some of the games. Pretty advanced stuff for the browser but it will happen eventually.

Yes， I want real time procedural movements. And I look forward the B4W's new function about IK.

Hi Will, I still could't calculate the bones bones coordinates from the bones angel and the length of bone, because only the quadruples can calculate the final point from the original point, but I got an error result.

I can look at it if you want to upload your project (or a simple demo with your issue). In your Project Manager, you can hit the Export Project(s) button and then attach the zip file you get to your post.
