3D Modeling and Display
3D Model Types
Wireframe Surface Solid Parametric
Wireframe Models
3D model created with ordinary lines, circles, arcs, etc., to represent edges
Only vertex and edge data is stored
No shading, hidden line removal
Surface Models
Model with surface objects
Meshes frequently used to represent surfaces Z
Surface, edge, & vertex (10,100,100) information stored
Shading, hidden line removal (0,0,0)
Useful for modeling shapes X
with complex curvature (e.g., hull forms, airfoils, automobiles)
Surface Model
6 meshed surfaces
Solid Models
Model with solid objects (e.g., primitives, sweeps)
Database contains information about vertices, Z edges, surfaces, and the space enclosed by the surfaces
(100,100,100)
Mass and material
properties (0,0,0)
Interference checking
Shading and hidden line removal
X
Solid Model
1 primitive
