mgf's Issues
Comparison with rhusics
Support SIMD implementations of certain algorithms
Some algorithms can be substantially improved by adding SIMD versions of them, or simply enabling the SIMD feature in cgmath. This should be done in the future.
Bump cgmath to 0.18.0
The new cgmath has some nice helpers added.
The CHANGELOG.md specifies a breaking change however: https://github.com/rustgd/cgmath/blob/master/CHANGELOG.md
Breaking: Quaternion memory layout changed to [x, y, z, w]. The From and Into impls for [S; 4] and (S, S, S, S) have been changed accordingly.
The data has moved from
pub struct Quaternion {
pub s: S,
pub v: Vector3,
}
To
pub struct Quaternion {
pub v: Vector3,
pub s: S,
}
I'm not sure if mgf depends on from/to [S;4] or (S,S,S,S). It seems unlikely to me, since those are mostly for interfacing to something like OpenGL, but I wanted to raise the issue here.
Instability near corners in non-convex meshses
As shown in mgf_demo/balls, some objects near the edge of the "box" exhibit instability and sink far to deeply into the floor. I have a few theories on why this happens, more than likely it is due to considering the wall and floor as the same physical object.
Capsule physics resolutions is broken
Somehow I broke this when converting to a crate, I'll try to get it fixed by Friday.

is this project dead?
Contact structures contain redundant information
Contact currently stores both contact points along with the normal. This can be reduced to simply one contact point, a normal, and a distance.
Demos segfault at exit on Wayland
This seems to be a problem relating to how wayland and glutin handles cursors. Looking into it, but it's not a huge problem.
Pool container is incomplete
There are number of poor interface choices in Pool. PoolEntry for one should not be exposed, and Pool should implement some sort of Drain. All of these need to be fixed by implementing custom iterators.
