Method Details

findPick

public static void findPick(Spatial spatial,
 Ray3 ray,
 PickResults results)

Finds a pick using the given ray starting at the scenegraph given as spatial. Results are stored in the given results value. NB: Spatials with CullHint ALWAYS will be skipped.

Parameters:

spatial - the spatial

ray - the ray

results - the results

findPick

public static void findPick(Spatial spatial,
 Ray3 ray,
 PickResults results,
 boolean ignoreCulled)

Finds a pick using the given ray starting at the scenegraph given as spatial. Results are stored in the given results value.

Parameters:

spatial - the spatial

ray - the ray

results - the results

ignoreCulled - if true, Spatials with CullHint ALWAYS will be skipped.

findCollisions

public static void findCollisions(Spatial spatial,
 Spatial scene,
 CollisionResults results)

hasPrimitiveCollision

public static boolean hasPrimitiveCollision(Mesh testMesh,
 Mesh toCheck)

This function checks for intersection between this mesh and the given one. On the first intersection, true is returned.

Parameters:

testMesh - The mesh

toCheck - The intersection testing mesh.

Returns:

true if they intersect.

findPrimitiveCollision

public static void findPrimitiveCollision(Mesh testMesh,
 Mesh toCheck,
 List<PrimitiveKey> testIndex,
 List<PrimitiveKey> otherIndex)

This function finds all intersections between this mesh and the checking one. The intersections are stored as PrimitiveKeys.

Parameters:

testMesh - The mesh

toCheck - The Mesh to check.

testIndex - The array of PrimitiveKeys intersecting in this mesh.

otherIndex - The array of PrimitiveKeys intersecting in the given mesh.

hasCollision

public static boolean hasCollision(Spatial spatial,
 Spatial scene,
 boolean checkPrimitives)
