The SolidViz extension provides solid modeling nodes for describing 3D shapes as combinations of other shapes using Boolean operations such as merge, intersection, and subtraction.
NOTE: SolidViz is not a separately licensed extension. You must have an OpenInventor license string.
CSG stands for Constructive Solid Geometry. It is a powerful method for describing a 3D shape as a combination of simpler 3D shapes using the Boolean operations merge (union), intersection, and subtraction. For instance, the expression "(AB)+C" means remove B from A, then merge the result with C. This is called a CSG expression, describing a CSG tree.
Actual computation of the geometry resulting from a CSG expression can be a slow process, at least not fast enough for realtime updates in interactive applications.
However a visual simulation of a CSG shape can be achieved in many cases at interactive speed by a special rendering method taking advantage of accelerated OpenGL rendering and the stencil buffer.
SolidViz implements a visual simulation of CSG shapes.
A new group node (SoCSGGroup
) allows the specification of a CSG expression.
Note: Some additional classes for computing the actual geometry are provided on an "asis" basis, with no support or warranty. See the SolidViz directory $OIVHOME/examples/source/SolidViz/examples/csgAction and $OIVHOME/examples/source/SolidViz/examples/csgOperation.
SoSolidViz
Initialization class
SoCSGGroup
Group node for interactive CSG rendering
SoCSGGroup
This group node performs a Constructive Solid Geometry (CSG) rendering. The children of this group define the solids that are involved in the CSG models.
The steps required to realize an interactive rendering of a CSG shape are the following:
SoCSGGroup
.
SoCSGGroup
as there are solid shapes.
SoCSGGroup
.
SoCSGGroup
to the scene graph.
The example program $OIVHOME/examples/source/SolidViz/examples/csgGroup.cxx shows these steps.
SoCSGGroup
produces the visual effect of the specified CSG operations, but the actual geometry is not modified. Open Inventor picking operates on the actual geometry. For example, if a cube has a cylindrical "hole" cut out of it using CSG rendering, picking on the "hole" will return a pick path to the geometry used to cut out the hole.
