Simulations

This week the goal was to have my simulations done and lookdev started.

Whats Done:

• Initial simulations created

• Tested infection solver for procedural destruction

• Adjusted sourcing for grains to include particle size variation

• Tested a grain upscale solution

To Do:

• More simulation versions

• Add additional POP sim for higher velocity particles

• LookDev

• Setup Cull to Camera

I ended up running into trouble early on trying to get the infection solver to work in conjunction with my simulation…

I used this tutorial by Fabricio Chamon as a basis for the solver

The plan was to take the infection solver, and take the infected points, then transfer the value of infected to pintoanimation and stopped variables.

This solve, while the infection looked good, was fairly intensive, and I felt the need for it to be cached out. The only issue with that is that I needed, not only the information of the frames, but the sub frames as well as to avoid the issue of banding.

I figured this would be an easy fix, just cache out the sub-frames, and call it a day, but when I tried to do that, I couldn’t read them in in my file. This is how I learned through THIS that the expression $FF tends to have floating point errors, and is not accurate, and thus cannot be used to write files out.

I plan on exploring this in the future, but for this week, I wanted a finished simulation, so that issue went on the back-burner, and I chose to explore less intensive methods of animating my attributes.
