how to render animation?

[lucasjinreal]

thanks for this wonderful lib. How to make Saba able to render animation driven by vmd animation keyframes?

See below for a simple rendering sample.

• simple_mmd_viewer_glfw.cpp
• simple_mmd_viewer_dx11.cpp

VMD Animation Update: MMDModel::UpdateAllAnimation()

[lucasjinreal]

@benikabocha thanks, it's promising. So that I can reveal almost the same function as original MMD.

I have one more question, I using Saba_viewer to view a pmx model file. I can saw that it can view a very tiny animation on static model (like tiny waving on hair), how does this implemented? Saba_view only render the static model imo?

saba_viewer can uses to:

• VMD animation files can be assigned to models.
• Assign VMD camera animations.
• .obj and .x files can be loaded.

How to play animations:

1. Drag and drop .pmx files into saba_viewer.
2. Drag and drop .vmd files into saba_viewer.
3. Click on "Animation" in the "Controls" window.
4. Click the "Play" button.

The hair animation is a physical animation. The physical animation is always playing in saba_viewer.

@benikabocha thanks. what is physical animation? how does that information stored beside the pmx model itself?

[benikabocha]

MMD physics animation is the result of a physics simulation set to a node. A node can have several rigid bodies.
