MESH_B

MESH_B generates a mesh which approximates the Bezier surface defined by the specified control points. The surface evaluation may happen in two different modes, static mode and adaptive mode. Adaptive mode is being chosen, if subdiv_n or subdiv_m is less than or equal to 2. Otherwise, the static mode will be chosen and parameter value rise will be ignored.

Syntax

MESH_B m, n, subdiv_n, subdiv_m, rise, x11, y11, z11, x12, y12, z12, ... , x1m, y1m, z1m, x21, y21, z21, x22, y22, z22, ... , x2m, y2m, z2m, ... , xn1, yn1, zn1, xn2, yn2, zn2, ... , xnm, ynm, znm

Parameters

m, n (integer): number of nodes along the X resp. Y axis

subdiv_n, subdiv_m (integer): number of subdivisions in the corresponding direction

rise (integer, >0): valid values must be greater than 0

xij, yij, zij (decimal): X, Y and Z coordinates of the nodes

Remarks

Modes for surface evaluation:

> In the static mode, the surface is being evaluated at subdiv_n and subdiv_m parameter values.

> In the adaptive mode, the surface is being evaluated at as many parameter values as needed, to guarantee the following: Distance from surface to the mid of each resulting mesh face is less than or equal to the parameter value rise.
