4 Data Structures
TQ3Param2D
and TQ3Param3D
data structures to represent two- and three-dimensional parametric points.
typedef struct TQ3Param2D { float u; float v; } TQ3Param2D; typedef struct TQ3Param3D { float u; float v; float w; } TQ3Param3D;The u, v, and w components are sometimes represented by the letters s, t, and u, respectively. This book always uses u, v, and w.<8bat>uu
The u component of a parametric point.v
The v component of a parametric point.w
The w component of a parametric point.
