Bone Rotations
Hello,
When I run the following code, I don't get 0,0,0 output as I expect. Code:
male = viz.add('vcc_male.cfg') male.setEuler([0,0,0]) male.setPosition([0,0,0]) male_pelvis = male.getBone('Bip01 Pelvis') male_pelvis.lock() male_pelvis.setEuler([0,0,0],viz.ABS_PARENT) male_pelvis.setEuler([0,0,0],viz.ABS_GLOBAL) print male_pelvis.getName() print male_pelvis.getEuler(viz.ABS_PARENT) print male_pelvis.getEuler(viz.ABS_GLOBAL) print '\n' Thanks, Stephen |

I ran the following code:
Code:
male_pelvis.setEuler([0,0,0],viz.ABS_PARENT) print male_pelvis.getEuler(viz.ABS_PARENT) male_pelvis.setEuler([0,0,0],viz.ABS_GLOBAL) print male_pelvis.getEuler(viz.ABS_GLOBAL) male_pelvis.setEuler([0,0,0],viz.AVATAR_WORLD) print male_pelvis.getEuler(viz.AVATAR_WORLD) Code:
[0.0, 0.0, 0.0] [-3.4150864394177916e-006, 0.0, 0.0] [-2.4426660780868525e-012, 6.5951979988376763e-011, 0.0] |

Ok, I think I kinda see. So each bone has a few different rotations that are combined? Like, it has its own, then gets rotated by the avatar world rotation? Since without the WORLD one, the code I originally posted gave me this:
[90.0, 8.8792461610864848e-005, -90.0] [-3.4150864394177916e-006, 0.0, 0.0] Even though I set the GLOBAL to 0,0,0. How come? |

No, each bone has a single position/rotation. The different mode options simply specify in which coordinate frame you want to set the value of the bone. In your code the line:
Code:
male_pelvis.setEuler([0,0,0],viz.ABS_PARENT) |

Ok, that's what I needed to know. Thanks!

Bones transforms_behave_differently_to node3d
From <node3d>.getEuler() and <node3d>.setEuler(), the viz.ABS_PARENT transform mode works in the PARENT's coordinate system.
But for <bone>.getEuler() and <bone>.setEuler(), the viz.ABS_PARENT transform mode works in the LOCAL coordinate system. |
