Is it possible to model the Universe in an object oriented manner from the subatomic level upwards?

While I'm certain this must have been tried before, I cant seem to find any examples of this concept being done myself. What I'm describing goes off of the idea that effectively you could model all "things" which are as objects. From their you can…

2d double array to image

I'm currently working on a simulation with continuous agents, which leave a pheromone trail on a 2d double array. The pheromone trails need to be on a 2d array because of a diffusion with a mean filter that needs to be performed. Ultimately, I need…
