- * - `vec3 getLocalPosition`: Update the position of vertices before transforms are applied. It takes in `vec3 position` and must return a modified version.
- * - `vec3 getWorldPosition`: Update the position of vertices after transforms are applied. It takes in `vec3 position` and pust return a modified version.

- * - `vec3 getWorldNormal`: Update the normal after transforms are applied. It takes in `vec3 normal` and must return a modified version.
- * - `vec2 getUV`: Update the texture coordinates. It takes in `vec2 uv` and must return a modified version.
- * - `vec4 getVertexColor`: Update the color of each vertex. It takes in a `vec4 color` and must return a modified version.
- * - `void afterVertex`: Called at the end of the vertex shader.
- * - `void beforeFragment`: Called at the start of the fragment shader.
