Registers a callback to modify the properties of each vertex before any transformations are applied in the vertex shader. This hook can be used inside baseColorShader().modify() and similar shader modify() calls to move, color, or otherwise modify the raw model data. The callback receives an object with the following properties:
position: a three-component vector representing the original position of the vertex.normal: a three-component vector representing the direction the surface is facing.texCoord: a two-component vector representing the texture coordinates.color: a four-component vector representing the color of the vertex (red, green, blue, alpha).
Return the modified object to update the vertex.

getCameraInputs
Registers a callback to adjust vertex properties after the model has been transformed by the camera, but before projection, in the vertex shader.
getColor
Registers a callback to set the final color for each pixel in a filter shader.
getFinalColor
Registers a callback to change the final color of each pixel after all lighting and mixing is done in the fragment shader.
