    There are two separate things here, interpenetration due how contacts/constraints are solved, and whether you do continuous collision sub-stepping or not. For stability and perform…

    I'm not an expert in the topic, but my understanding is RGB is a poor color space for computing color difference. This could be why your mosaics end up so washed out. [1] suggests …

    Worth noting that ucontext is quite slow (at least on linux): https://www.boost.org/doc/libs/1_67_0/libs/context/doc/html/...

    Your rotation widget is nonstandard compared to most other 3D editors. See for example Blender[1] or Maya's[2] widgets (which are both basically the same). It's also kind of confus…

    I would try unrolling 2-4 iterations of the loop. Multiple sequential loads isn't much slower than a single load, so batching your loads and stores together will let you do more ar…

    Depending on the latitude sunset might be when people just start to get off work, or it might be well after dinner. Times have more semantic meaning than just the position of the s…

    Despite the fact that signed overflow/underflow is undefined behavior I'm pretty sure that many more bugs have resulted from unsigned underflow than signed overflow or underflow. W…
