T6 - Object representations and Modeling

Continuous surfaces and parametric modeling are common in

It is common to transform a point cloud to a continuous surface

Implicit respresentations are done through equations and formulas

Point clouds are

A 3D sphere can be represented as

Extrude is the operation to modify

Point clouds are common in

LIDAR scans and photogrametry generate

It is common to model point clouds by hand

Topology is relevant for

NURBS and T-Splines are used for

Topology is

The transformation from 3D polygon meshes to continuous surfaces is easy

Two polygon meshes can have different topology and look the same when rendered

Polygonal meshes are explicit representations

Modeling 3D polygon meshes is

Point clouds and implicit representations can be used in the same scene

Implicit representations are good for

3D polygon meshes are common in

Medical imaging use
