Parasolid is a geometric modeling kernel originally developed by Shape Data Limited , now owned and developed by Siemens Digital Industries Software . It can be licensed by other companies for use in their 3D computer graphics software products.
4-744: Parasolid's capabilities include model creation and editing utilities such as Boolean modeling operators , feature modeling support, advanced surfacing, thickening and hollowing, blending and filleting and sheet modeling. It also incorporates modeling with mesh surfaces and lattices. Parasolid also includes tools for direct model editing, including tapering, offsetting, geometry replacement and removal of feature details with automated regeneration of surrounding data. Parasolid also provides wide-ranging graphical and rendering support, including hidden-line, wireframe and drafting, tessellation and model data inquiries. Parasolid parts are normally saved in XT format, which usually has
8-773: Is used in many Computer-aided design (CAD), Computer-aided manufacturing (CAM), Computer-aided engineering (CAE), Product visualization , and CAD data exchange packages. Notable uses include: This graphics software –related article is a stub . You can help Misplaced Pages by expanding it . Boolean operations on polygons Boolean operations on polygons are a set of Boolean operations (AND, OR, NOT, XOR, ...) operating on one or more sets of polygons in computer graphics. These sets of operations are widely used in computer graphics , CAD , and in EDA (in integrated circuit physical design and verification software). Early algorithms for Boolean operations on polygons were based on
12-496: The file extension .X_T . The format is documented and open. There is also a binary version of the format, usually with an .X_B extension, which is somewhat more compact. Both .X_T and .X_B are used for parts files. To use Parasolid effectively, software developers need knowledge of CAD in general, computational geometry and topology . Parasolid is available for Windows (32-bit, 64-bit and ARM64), Linux (64-bit and ARM64), macOS (Intel and Apple Silicon), iOS, and Android. It
16-687: The use of bitmaps . Using bitmaps in modeling polygon shapes has many drawbacks. One of the drawbacks is that the memory usage can be very large, since the resolution of polygons is proportional to the number of bits used to represent polygons. The higher the resolution is desired, the more the number of bits is required. Modern implementations for Boolean operations on polygons tend to use plane sweep algorithms (or Sweep line algorithms ). A list of papers using plane sweep algorithms for Boolean operations on polygons can be found in References below. Boolean operations on convex polygons and monotone polygons of
