"I I think it gives people an idea that we're like a Montessori school for systems people. And it's like hey everyone come in and just do whatever you want. Do you wanna eat the Play Doh today? Ok eat the Play Doh... I feel like that's not really accurate"

Rust wrapped Jolt Physics visualized in Bevy- each ray-cast simulated lidar point is an individually translated sphere
youtu.be/I2yfPAyACps?...

A nice feature with rerun with the buffering of recent data in rerun is that I can build, run a simulation of so many steps faster than real time, replay some then make changes and recompile, but continue to watch the sim in rerun and scrub around in time while waiting (and maybe make more changes).

@rerun.io for visualization again, though the movement over the terrain is not obvious- directional lighting and shadows would help (rviz doesn't have shadows but does have camera aligned lighting). I could bake some shading into the mesh triangle colors, or other rerun features could help?

```
cxx_build::bridge...
.define("JPH_DEBUG_RENDERER", Some("1"))
.define("JPH_PROFILE_ENABLED", Some("1"))
```

Now can run the hello world through cxx, can resume with the vehicle example next

Need to match these:
```
Version mismatch, make sure you compile the client code with the same Jolt version and compiler definitions!
Mismatching define JPH_PROFILE_ENABLED.
Mismatching define JPH_DEBUG_RENDERER.
```

Maybe will get an answer here github.com/dtolnay/cxx/... though it isn't really a cxx issue

Does 'links' help? doc.rust-lang.org/cargo/refere...

First question is can I use header files that are pulled in by a dependency (joltc-sys) in my `build.rs`? It looks like it automatically knows about target/release/build/joltc-...hash.../out/lib/libJolt.a, I can link that, but how to include 'joltc-sys-.../out/include/' in cxx_build?

The next thing needed is a HeightField to drive over, but that isn't in the jolt-rust JoltC currently- github.com/amerkoleci/j... which is a different jolt c wrapper does have it, but making a rust wrapper for that is daunting. Should I just do nearly everything in C++, wrap in rust at high level?

Have a sim vehicle in jolt-rust working with stacked hinges for wheel rotation and steering on two of four wheels, no suspension, visualized in @rerun.io:

But now I'm seeing the SixDOFConstraintSettings is missing the MotorSettings... maybe I should just make slider constraints and add separate steering and rolling hinges?

What about GroupFilterTable? I see JPC_GroupFilter but no table- what does the table do?

But VehicleSixDOFTest.cpp only needs SixDOFConstraintSettings which is already in JoltC, so that's the example to follow for now

Now looking at VehicleConstraintTest.cpp there are several things that don't exist in JoltC: VehicleConstraintSettings & WheelSettingsWV (which extends WheelSettings) - the first looks to be easy to add, there are many other *ConstraintSettings in JoltC to follow the example of.
