-- ==========
SetBoolVoxels(me : mutable;
theVoxels : Address from Standard);
---Purpose: <theVoxels> is a Voxel_BoolDS* object.
SetColorVoxels(me : mutable;
theVoxels : Address from Standard);
---Purpose: <theVoxels> is a Voxel_ColorDS* object.
SetROctBoolVoxels(me : mutable;
theVoxels : Address from Standard);
---Purpose: <theVoxels> is a Voxel_ROctBoolDS* object.
SetTriangulation(me : mutable;
theTriangulation : Triangulation from Poly);
---Purpose: Sets a triangulation for visualization.
---Category: Visual attributes
-- =================
SetDisplayMode(me : mutable;
theMode : VoxelDisplayMode from Voxel);
---Purpose: Sets a display mode for voxels.
SetColor(me : mutable;
theColor : Color from Quantity)
---Purpose: Defines the color of points, quadrangles ... for BoolDS.
is redefined;
SetColors(me : mutable;
theColors : HArray1OfColor from Quantity);
---Purpose: Defines the color of points, quadrangles... for ColorDS.
-- For ColorDS the size of array is 0 .. 15.
-- 0 - means no color, this voxel is not drawn.
SetPointSize(me : mutable;
theSize : Real from Standard);
---Purpose: Defines the size of points for all types of voxels.
SetQuadrangleSize(me : mutable;
theSize : Integer from Standard);
---Purpose: Defines the size of quadrangles in per cents (0 .. 100).
SetTransparency(me : mutable;
theTransparency : Real from Standard)
---Purpose: Defines the transparency value [0 .. 1] for quadrangular visualization.
is redefined;
Highlight(me : mutable;
ix : Integer from Standard;
iy : Integer from Standard;
iz : Integer from Standard);
---Purpose: Highlights a voxel.
-- It doesn't re-computes the whole interactive object,
-- but only marks a voxels as "highlighted".
-- The voxel becomes highlighted on next swapping of buffers.
-- In order to unhighlight a voxel, set ix = iy = iz = -1.

Allocate(me : mutable)
---Purpose: Allocates the data structure of visualization.
is private;
Destroy(me : mutable);
---C++: alias ~
---Purpose: A destructor of presentation data.
SetDegenerateMode(me : mutable;
theDegenerate : Boolean from Standard);
---Purpose: Simplifies visualization of voxels in case of view rotation, panning and zooming.
SetUsageOfGLlists(me : mutable;
theUsage : Boolean from Standard);
---Purpose: GL lists accelerate view rotation, panning and zooming operations, but
-- it takes additional memory...
-- It is up to the user of this interactive object to decide whether
-- he has enough memory and may use GL lists or
-- he is lack of memory and usage of GL lists is not recommended.
-- By default, usage of GL lists is on.
-- Also, as I noticed, the view without GL lists looks more precisely.
SetSmoothPoints(me : mutable;
theSmooth : Boolean from Standard);
---Purpose: Switches visualization of points from smooth to rough.
SetColorRange(me : mutable;
theMinValue : Byte from Standard;
theMaxValue : Byte from Standard);
---Purpose: Defines min-max values for visualization of voxels of ColorDS structure.
-- By default, min value = 1, max value = 15 (all non-zero values).
SetSizeRange(me : mutable;
theDisplayedXMin : Real from Standard;
theDisplayedXMax : Real from Standard;
theDisplayedYMin : Real from Standard;
theDisplayedYMax : Real from Standard;
theDisplayedZMin : Real from Standard;
theDisplayedZMax : Real from Standard);
---Purpose: Defines the displayed area of voxels.
-- By default, the range is equal to the box of voxels (all voxels are displayed).
