Algorithm to draw particles in correct order?
::mat4 model;
glm::mat4 view;
glm::mat4 projection;
int particleToDraw = drawOrder [particle];
model = glm::translate( model, glm::vec3 ( smokeParticles [particleToDraw].position.x, smokeParticles [ … particleToDraw].position.y + 10.0f, smokeParticles [particleToDraw].position.z ) );
model = glm::scale(model, glm::vec3 ( smokeParticles [particleToDraw].scaleFactor ) );
glm::vec3 diff = glm::normalize …
