Example 6 with DistanceGrid

use of maspack.geometry.DistanceGrid in project artisynth_core by artisynth.

the class RigidBody method getDistanceGrid.

/**
 * Returns a signed distance grid that can be used with a
 * SignedDistanceCollider, or <code>null</code> if a grid is not available
 * (i.e., if {@link #hasDistanceGrid} returns <code>false</code>).
 * The number of divisons in the grid is controlled explicitly by the
 * property <code>distanceGridRes</code>, or, that is 0, by the property
 * <code>distanceGridMaxRes</code>. If both properties are 0, no grid is
 * available and <code>null</code> will be returned.
 *
 * @return signed distance grid, or <code>null</code> if a grid is
 * not available this RigidBody
 * @see #getDistanceGridMaxRes
 * @see #getDistanceGridRes
