Example integration with filament

[liuhangb]

Recently, I try to use google filament engine to render 3d model, but no animation; I have confused about intergrat ozz animation to filament; If possible, provide some document to help intergration easily, thanks very much.

Hi,

Disclaimer: I've never used Google Filament.

I assume your objective is to play animations and skin a mesh, right?

Here's what I'd recommend:

• Start by getting used to ozz API with a simple example like animation playback one. You'll see how to load skeleton, animations and play them.
• Then look at ozz skinning job, and get to understand OpenGL implementation in ozz sample framework. Additive sample uses it, if you need to see how the mesh is loaded and skinning matrices computed.
• Finally you'll need a way with Filament to have kind of dynamic vertex buffers, so you can update the mesh each frame. Looking very quickly at the API I think that's what vk_animation sample does. So your job is going to repro what ozz sample OpenGL framework does with Filament API.

Hope it helps,
Guillaume
