| Voxel_CollisionDetection () | |
| An empty constructor. More... | |
| Voxel_CollisionDetection (const Standard_Real deflection, const Standard_Integer nbx, const Standard_Integer nby, const Standard_Integer nbz) | |
| A constructor. It defines deflection of triangulation for the shapes. As lower the deflection is, as proper the triangulation is generated. Also, it defines number of splits along X, Y and Z axes for generation of voxels. As greater the numbers are, as greater number of voxels is used for detection of collision. More... | |
| Standard_Integer | AddShape (const TopoDS_Shape &shape) |
| Adds a shape. Returns an index of the shape. More... | |
| Standard_Boolean | ReplaceShape (const Standard_Integer ishape, const TopoDS_Shape &shape) |
| Replaces a shape by another one. <ishape> is an index of the shape. This method is useful for moving shape, for example. More... | |
| void | SetDeflection (const Standard_Real deflection) |
| Defines the deflection of triangulation of shapes. More... | |
| void | SetNbVoxels (const Standard_Integer nbx, const Standard_Integer nby, const Standard_Integer nbz) |
| Defines the number of voxels along X, Y and Z axes. More... | |
| void | SetBoundaryBox (const Bnd_Box &box) |
| Defines a user-defined boundary box for generation of voxels. If this method is not called, the algorithm calculates the boundary box itself. More... | |
| void | SetUsageOfVolume (const Standard_Boolean usage) |
| Defines usage of volume of shapes in collision detection algorithm. Beware, usage of volume a little bit decreases the speed of algorithm. More... | |
| void | KeepCollisions (const Standard_Boolean keep) |
| Doesn't clean the collision points on new call to the method Compute(). It allows to see the collisions for a moving shape. More... | |
| Standard_Boolean | Voxelize (const Standard_Integer ishape=-1) |
| Prepares data for computation of collisions. It checks the inner parameters (number of voxels along X, Y and Z axes) and voxelizes the shapes. If the shape is not changed since the last call to this method, this method may be not called for this shape. <ishape> - is the index of the shape for processing by this method. If it is equal to -1, all shapes will be processed. More... | |
| Standard_Boolean | Compute () |
| Computes the collisions. This method may be called many times if, for example, the shapes are being moved. More... | |
| Standard_Boolean | HasCollisions () const |
| Returns true if a collision is detected. More... | |
| const Voxel_BoolDS & | GetCollisions () const |
| Returns the collided voxels. More... | |
