Detailed Description

A weld joint fully constrains the relative transform between two bodies while allowing for springiness.

A weld joint constrains the relative rotation and translation between two bodies. Both rotation and translation can have damped springs.

Note: The accuracy of weld joint is limited by the accuracy of the solver. Long chains of weld joints may flex.

Data Structure Documentation

struct b3WeldJointDef

Weld joint definition Connects two bodies together rigidly.

This constraint provides springs to mimic soft-body simulation.

Note: The approximate solver in Box3D cannot hold many bodies together rigidly
