[commited] programmatically creating mesh-animations with face-anim-demo (4 posts)

    Hola, I just had a look into Ogre's mesh-animations. It works quite good as long as you import it from a .mesh.xml-file.

    But if you want to create a MeshAnimation in java it is getting complicated. Poses were only assigned to MeshAnimations so it was acutally only possible to access them by a PoseAnimation. If you didn't had any the poses were lost.

    Therefore I made some changes with an additional class (MeshAnimationWrapper) which gives you the ability to create KeyFrames for certain poses at a specified time.

    BTW: I actually wanted to create something like Ogre3d's facial-animation-sample and a demo is added as well
    It would be nice to get some feedback, about what works and what not.

    I will wait quite a time until I commit this as it is quite a sensible region in the code.

    I will attach the patch and a test as file.

    Ah I have to mention that I used swt for the GUI and did that quick and very dirty.
    So somehow the event-dispatch is not working properly. From time to time you have
    press several times on the slider in order to change the mesh (just dragging didn't
    work neither…but I think for showing it is enough)

    Here a screenshot:

    Ok,…it is commited.

    I added a Test in jmetest.ogrexml which will demonstrate how to use
    attached poses programatically like this: 

    // There values are (pose,time for keyframe, weight of pose):
      manualAnimationWrapper.addPoseKeyFrame("MouthOpen", 2f,0);
      manualAnimationWrapper.addPoseKeyFrame("MouthOpen", 4f,1);
      manualAnimationWrapper.addPoseKeyFrame("MouthOpen", 4.5f,1);
      manualAnimationWrapper.addPoseKeyFrame("MouthOpen", 5f,0);

    It also demonstrates how to combine both skeletal and meshanimation with
    that wonderful AnimationChannels.

    PS: I realized that I still have to implements savable for new data…. <–
