Hi, While I'm studying WebGL, I'm wondering how to use vertex shader with Pixi.js. Using fragment shaders is quite clear in my mind, but I'm still confused on how to send vertices coordinates to a vertex shader in Pixi.js. For instance, assuming we have such a vertex shader: // vertex shader attribute vec3 aVertexPosition; uniform mat4 uMVMatrix; uniform mat4 uPMatrix; void main(void) { gl_Position = uPMatrix * uMVMatrix * vec4(aVertexPosition, 1.0); } and we have such ver
