Solid modelling
This article is a stub. You can help Wikipedia by fixing it.Solid modeling studies unambiguous representations, models of solid objects suitable for computer processing. It is also known as volume modelling.
Basic representation techniques
- Parameterized primitive instancing.
- An object is specified by the reference to the library of parameterized primitives (e.g., library of nuts and bolts).
- Sweeping
- An object is specified in terms of volumes "swept out" by moving of a primitive along a simple curve. These volumes either add to the object ("extrusion") or remove material ("cutter path").
- Spatial occupancy
- The whole space is subdivided into regular cells, and the object is specified by the set of cells it occupies.
- Decomposition
- Similar to "spatial occupancy", but the cells are neither regular, nor "prefabricated".
- Constructive solid geometry.
- Boundary representation
- A solid object is represented by surfaces of its boundary.
- A solid object is represented by surfaces of its boundary.
