Bouncing velocity threshold is useful to prevent unstable box stacking when the restitution is non-zero. Currently, the value of it is a randomly picked constant. It would be good to...
There are some options we can choose for forward dynamics simulation step. They are integration method, handling method for velocity constraints and position constraints. There could be number of combination...
1. DART creates meshes for primitive geometries and conduct collision detection using FCL. It sometimes makes unnatural looking result because the collision result is not analytical solution. For example, a...
libccd is a nice collision detection library for convex shapes. Thanks to @danfis for this great work! I've been using libccd for many years through [FCL](https://github.com/flexible-collision-library/fcl) for the collision detection...
We uses 3x3 matrix for rotation representation but generally quaternion multiplication is much faster than 3x3 matrix multiplication.
The most recent version of `SDF` is `SDF 1.5` but `SdfParser` (`SoftSdfParser` will be merged to `SdfParser`) currently DART supports only `SDF 1.4`. Since `SDF 1.4` and `SDF 1.5` are...
Two kinds of relationship: - Super object and sub object - Parent object and child object Example: - `World` is a super object of `Skeleton` - `Skeleton` is a super...
`BodyNode` has multiple functionalities and it makes the API complex. `Inertia` will take mass, moment of inertia, and center of mass properties from `BodyNode`. - [x] Deprecate APIs related to...
This can be used to simulate proximit sensors, or to take point samples of objects to simulate LIDAR (#346).
