Procedural Animation - Cauldron

This code display a scene in loading some external .obj meshes: A cauldron and a spoon

• Note: The meshes files are stored in the directory assets/. This directory should be accessible from the place where your executable is run.

A set of particles (one displayed as sphere, and the other using a semi-transparent textured mapped onto a quad) are emited regularily.
> Modify the code to model a scene similar to the following one.

• Tips

• • - When dealing with the billboards, you may debug your trajectory in displaying a sphere instead of the semi-transparent texture.
  • - The billboards should always face the camera.
  • - The uniform value material.alpha can send an alpha value to the shader to model a global time varying transparency level.
