public GImpactShapeInterface()

Method Detail

updateBound

public void updateBound()

Performs refit operation.

Updates the entire Box set of this shape.

postUpdate() must be called for attemps to calculating the box set, else this function will does nothing.

if m_needs_update == true, then it calls calcLocalAABB();

getAabb

public void getAabb(Transform t,
                    Vector3f aabbMin,
                    Vector3f aabbMax)

If the Bounding box is not updated, then this class attemps to calculate it.

Calls updateBound() for update the box set.

Specified by:

getAabb in class CollisionShape

postUpdate

public void postUpdate()

Tells to this object that is needed to refit the box set.

getLocalBox

public com.bulletphysics.extras.gimpact.BoxCollision.AABB getLocalBox(com.bulletphysics.extras.gimpact.BoxCollision.AABB out)

Obtains the local box, which is the global calculated box of the total of subshapes.

getShapeType

public BroadphaseNativeType getShapeType()

Specified by:

getShapeType in class CollisionShape

setLocalScaling

public void setLocalScaling(Vector3f scaling)

You must call updateBound() for update the box set.

Specified by:

setLocalScaling in class CollisionShape

getLocalScaling

public Vector3f getLocalScaling(Vector3f out)

Specified by:

getLocalScaling in class CollisionShape

setMargin

public void setMargin(float margin)

Overrides:

setMargin in class ConcaveShape

hasBoxSet

public boolean hasBoxSet()

Determines if this class has a hierarchy structure for sorting its primitives.

getNumChildShapes

public abstract int getNumChildShapes()

Gets the number of children.

childrenHasTransform

public abstract boolean childrenHasTransform()

If true, then its children must get transforms.

needsRetrieveTriangles

public abstract boolean needsRetrieveTriangles()

Determines if this shape has triangles.

needsRetrieveTetrahedrons

public abstract boolean needsRetrieveTetrahedrons()

Determines if this shape has tetrahedrons.

getBulletTriangle

public abstract void getBulletTriangle(int prim_index,
                                       TriangleShapeEx triangle)

lockChildShapes

Call when reading child shapes.

unlockChildShapes

public void unlockChildShapes()

getChildAabb

public void getChildAabb(int child_index,
                         Transform t,
                         Vector3f aabbMin,
                         Vector3f aabbMax)

Retrieves the bound from a child.
