Deformation Gradient The deformation gradient F serves as a fundamental tensor in continuum mechanics, capturing the local deformation of material points. It provides a complete description of stretch, shear, and rigid body rotation within an infinitesimal neighborhood around each material point. Mathematical Definition: The mapping relationshi ...

When simulating projectile impacts, calculating the angle between incoming trajectory and surface orientation determines whether the object adheres to the surface or rebounds. By comparing the normalized dot product against a configurable threshold, we can trigger a reflection sequence. vector trajectory = @v; vector surf_normal = normalize(@hi ...
