+package Graphic3d
+
+ ---Version:
+
+ ---Purpose: This package permits the creation of 3d graphic objects
+ -- in a visualiser.
+ -- These objects, called structures, are composed of groups of
+ -- primitives and attributes.
+ -- The group is the smallest editable element of a structure.
+ -- A structure can be displayed, erased, high-lighted.
+ -- A transformation can be applied to it.
+ -- Structures can be connected to form a tree of structures,
+ -- composed by transformations.
+ -- The visualiser permits global manipulation of structures.
+
+ ---Keywords: Structure, Group, Primitives, Line, Marker, Text,
+ -- FillAreas, Vertex, Vector, Material, Font, Shading

-
-is

-
-
- ---Category: Initialization
- -- ==============
-
- Create(deflection : Real from Standard;
- nbx : Integer from Standard;
- nby : Integer from Standard;
- nbz : Integer from Standard)
- ---Purpose: 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.
- returns CollisionDetection from Voxel;
-
- AddShape(me : in out;
- shape : Shape from TopoDS)
- ---Purpose: Adds a shape.
- -- Returns an index of the shape.
- returns Integer from Standard;
-
- ReplaceShape(me : in out;
- ishape : Integer from Standard;
- shape : Shape from TopoDS)
- ---Purpose: Replaces a shape by another one.
- -- <ishape> is an index of the shape.
- -- This method is useful for moving shape, for example.
- returns Boolean from Standard;
-
- SetDeflection(me : in out;
- deflection : Real from Standard);
- ---Purpose: Defines the deflection of triangulation of shapes.
-
- SetNbVoxels(me : in out;
- nbx : Integer from Standard;
- nby : Integer from Standard;
- nbz : Integer from Standard);
- ---Purpose: Defines the number of voxels along X, Y and Z axes.
-
- SetBoundaryBox(me : in out;
- box: Box from Bnd);
- ---Purpose: Defines a user-defined boundary box for generation of voxels.
- -- If this method is not called, the algorithm calculates the boundary box itself.
-
- SetUsageOfVolume(me : in out;
- usage : Boolean from Standard);
- ---Purpose: Defines usage of volume of shapes in collision detection algorithm.
- -- Beware, usage of volume a little bit decreases the speed of algorithm.
-
- KeepCollisions(me : in out;
- keep : Boolean from Standard);
- ---Purpose: Doesn't clean the collision points on new call to the method Compute().
- -- It allows to see the collisions for a moving shape.
-
-
- ---Category: Computation
- -- ===========
-
- -- Call the method in the following order:
- -- Voxelize();
- -- Compute();
-
- Voxelize(me : in out;
- ishape : Integer from Standard = -1)
- ---Purpose: 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.
- returns Boolean from Standard;
-
- Compute(me : in out)
- ---Purpose: Computes the collisions.
- -- This method may be called many times if, for example, the shapes are being moved.
- returns Boolean from Standard;
-
-
- ---Category: Result (collisions)
- -- ===================
-
- HasCollisions(me)
- ---Purpose: Returns true if a collision is detected.
- returns Boolean from Standard;

- ---C++: alias ~
- ---Purpose: A destructor.
-
- Clear(me : in out)
- ---Purpose: An internal method for cleaning the intermediate data.
- is private;

- CheckVoxels(me;

- y_len : Real from Standard;

- ---Purpose: A constructor initializing the voxel model.
- -- (x, y, z) - the start point of the box.
- -- (x_len, y_len, z_len) - lengths in x, y and z directions along axes of a co-ordinate system.
- -- (nb_x, nb_y, nb_z) - number of splits (voxels) along x, y and z directions.

- is redefined virtual;

- Destroy(me : in out);
- ---C++: alias ~
- ---Purpose: A destructor of the voxel model.
-
- SetZero(me : in out);
- ---Purpose: The method sets all values equal to 0 (false) and
- -- releases the memory.
-
- OptimizeMemory(me : in out);
- ---Purpose: The method searches voxels with equal-value of sub-voxels
- -- and removes them (remaining the value for the voxel).

- -- If the voxel is split into 8 sub-voxels, the split disappears.
- -- Initial state of the model is so that all voxels have value 0 (false),
- -- and this data doesn't occupy memory.

-
- Set(me : in out;
- ix : Integer from Standard;

- -- If the voxel is not split into 8 sub-voxels yet, this method splits the voxel.
- -- Range of sub-voxels is 0 - 7.

-
- Deepness(me;
- ix : Integer from Standard;
- iy : Integer from Standard;
- iz : Integer from Standard)
- ---Purpose: Returns the deepness of splits of a voxel.
- -- 0 - no splits (::IsSplit() being called would return false).
- -- 1 - the voxel is split into 8 sub-voxels.
- -- 2 - the voxels is split into 8 sub-voxels,
- -- and each of the sub-voxels is split into 8 sub-sub-voxels.
- -- 3 - ...
- returns Integer from Standard;
-
- Get(me;
- ix : Integer from Standard;
- iy : Integer from Standard;
- iz : Integer from Standard)
- ---Purpose: Returns the value of voxel with co-ordinates (ix, iy, iz).
- -- Warning!: the returned value may not coincide with the value of its 8 sub-voxels.
- -- Use the method ::IsSplit() to check whether a voxel has sub-voxels.
- returns Boolean from Standard;
