This class represents a 3D box shape.
Those axis are unit length. The three extents are half-widths of the box along the three axis x, y, z local axis. The "transform" of the corresponding body will give an orientation and a position to the box.
| RP3D_FORCE_INLINE const Vector3 & reactphysics3d::BoxShape::getHalfExtents | ( | ) | const |
Return the half-extents of the box.
|
overridevirtual |
Return the local bounds of the shape in x, y and z directions.
This method is used to compute the AABB of the box.
Implements reactphysics3d::CollisionShape.
|
overridevirtual |
Return the local inertia tensor of the collision shape.
| mass | Mass to use to compute the inertia tensor of the collision shape |
Implements reactphysics3d::CollisionShape.
| RP3D_FORCE_INLINE void reactphysics3d::BoxShape::setHalfExtents | ( | const Vector3 & | halfExtents | ) |
Set the half-extents of the box.
Note that you might want to recompute the inertia tensor and center of mass of the body after changing the size of the collision shape.
| halfExtents | The vector with the three half-extents of the box |
