Is there a method for animating rigged JSON models in WebGL without using three.js? I understand that loading the models is possible, but unsure of how to animate them.
If you're looking to animate a rigged model in THREE.js but don't want to use the built-in functionality, there are alternative methods you can consider.
Instead of relying on THREE.js's internal processes, you can manually pass matrix transforms and bone data to the vertex shader for animation. By providing bone indexes and weights to each vertex, you can instruct the shader to blend matrices accordingly to achieve the desired animations. This way, you have more control over how your model moves without solely relying on THREE.js's animation routines.
There are two commonly used approaches to handle this data - one involves using an "image texture" to store matrices and converting them within the vertex shader, while the other method involves passing a uniform matrix array directly. The latter method is typically preferable for newer graphics cards.
