1.功能代码
犀牛软件是一款专业的三维设计软件。简单实用方便，在三维矢量领域有着广泛的用途，开发拓展这款软件的插件，可以方便设计师摆脱一些繁重的重复劳动，有着现实的需求。作者整理了一个python开发的脚本，功能是获取曲面表面点和坐标点数组，作为范例，源代码如下：
# Creates an array of points on a surface
import rhinoscriptsyntax as rs
def ArrayPointsOnSurface():
# Get the surface object
surface_id = rs.GetObject("Select surface", rs.filter.surface)
if surface_id is None: return
# Get the number of rows
rows = rs.GetInteger("Number of rows", 2, 2)
if rows is None: return
# Get the number of columns
columns = rs.GetInteger("Number of columns", 2, 2)
if columns is None: return
# Get the domain of the surface
U = rs.SurfaceDomain(surface_id, 0)
V = rs.SurfaceDomain(surface_id, 1)
if U is None or V is None: return
# Add the points
for i in xrange(0,rows):
param0 = U[0] + (((U[1] - U[0]) / (rows-1)) * i)
for j in xrange(0,columns):
param1 = V[0] + (((V[1] - V[0]) / (columns-1)) * j)
point = rs.EvaluateSurface(surface_id, param0, param1)
rs.AddPoint(point)
# Check to see if this file is being executed as the "main" python
# script instead of being used as a module by some other python script
# This allows us to use the module which ever way we want.
if __name__ == "__main__":
# call the function defined above
ArrayPointsOnSurface()
