◆ collides() [1/2]

bool CollisionPredicates::collides ( const MeshEntity &  entity,
const Point &  point 
)
static

Check whether entity collides with point.

Arguments entity (MeshEntity) The entity. point (Point) The point.

Returns bool True iff entity collides with cell.

bool CollisionPredicates::collides ( const MeshEntity &  entity_0,
const MeshEntity &  entity_1 
)
static

Check whether two entities collide.

Arguments entity_0 (MeshEntity) The first entity. entity_1 (MeshEntity) The second entity.

Returns bool True iff entity collides with cell.
