Look at <morph>. It’s nothing fancy. There are limits to what can be done. COLLADA is fairly limited in terms of what it can express. You could say it’s primitive.
<morph> is a static mesh. A blend between mesh1 and mesh2. (0% mesh1 & 100% mesh2).
I don’t want a static mesh.
I want an <animation>, from mesh1 (with N vertices) to mesh2 (with N vertices again).
Is there an morphing animation example, anywhere?
<morph> holds the data. It probably cannot be readily visualized without a corresponding <animation>. Anyway, it’s all the same. It’s all blending that is.
