P E R F I C T A
-
A CSG modeller written in the C++ language and accessed through a call
interface.
-
Model sheets and wires as well as solids.
-
Define parameterized models within C++, using geometric data types, overloaded
operators and geometric transform functions.
-
Create primitives from arbitrary implicit polynomials, trigonometric functions,
exponentials and user-defined functions.
-
Define and attach attributes, and exploit inheritance.
P E R F R A C T A
-
Space division turns CSG into the efficient solid modelling technology.
-
Digital solids are supported en passant
-
Automatic sub-model commoning allows many different versions of a model
to be stored efficiently.
-
Use the division strategies provided, or implement your own using the built-in
facilities for interval arithmetic.
Q V A E R E N D O
-
Find interferences, distances and directed distances between objects.
-
Extract facets for graphics.
-
Implement your own tests on divided models.
-
Use programmable Monte Carlo methods together with point-membership tests
to obtain integral properties.
P E R F E C T A
-
Available on Sun, Linux/PC, Microsoft/PC, and Silicon Graphics computers.
-
On-line documentation from the same source as well-known textbooks in geometric
computing.
