I start in python. I try to make 3 small code in python to plot curve:
Say me what do you think, I thank you.
*************** code 1 *****************import Blender
from Blender import *
from Blender import NMesh
from math import pi, cos, sin, tan
print ‘______________________’
d=20
angle = 2*pi/d
angleini = angle/2
#le nouveau mesh
m=NMesh.GetRaw()
#boucle de construction des sommets
for n in range(2*d+1):
angle = angle + angleini
yn=tan(angle)
xn=1/cos(angle)
vert=NMesh.Vert(xn,yn,0.0)
m.verts.append(vert)
for n in range(2*d):
m.addEdge(m.verts[n], m.verts[n+1])
NMesh.PutRaw(m,‘courbe’)
for vertice in m.verts:
print 'Les coordonnees du vertice d’index ', vertice.index,
print 'sont ', vertice.co
print ‘Il y a’, len(m.verts)
Blender.Redraw()
