It'd be really cool to figure out some way to generalize this visualization scripting I'm working on. It generates a top-down visualization of some geometry showing where there's visibility and where things are occluded. It's kind of like a 2.5D rtarea. The visuals are awesome and the scripting is exercising a dozen tools. All I think is missing for this to be general is a way to specify eye points.

Would be a strong contender for conversion to a Qt interface too. That would obviously entail rewriting it, but I could see this being generally useful to some.

/me tests a setup with one of our sample models

Here's an example, showing the visibility zone for a driver in our m35 truck. I put an object (a post) in the truck's path and it shows the visibility difference too. Screen-Shot-2020-12-10-at-12.47.40-AM.png

This was all BRL-CAD tools, including the labeling. An orchestration of about a dozen tools.

Looks kinda like that'd be a fun game of some sort... :)

neat, looks... like... path tracing ?

Nope, just plain render with ambient occlusion

ah, the bed of the truck looked like it had scattering

it does, thats scattering from the ambient occlusion sampling. AO sampling has a random component.
