Member Function Documentation

void distance_field::SignedPropagationDistanceField::addPointsToField ( const std::vector< btVector3 > points ) [virtual]

Add (and expand) a set of points to the distance field.

This function will incrementally add the given points and update the distance field correspondingly. Use the reset() function if you need to remove all points and start afresh.

Implements distance_field::DistanceField< SignedPropDistanceFieldVoxel >.
