Sine Wave - Python Script

Support Modeling

Hi,

This is how to make a sine wave in Blender:

  • Create a new project (CTRL-x)
  • Go to the Text editor window (SHFT-F11)
  • Create some new text (RMB >> New)
  • Type in the following (be careful to use the correct indenting!):import math
    import Blender
    from Blender import NMesh

x = -1 * math.pi

mesh = NMesh.GetRaw()
vNew = NMesh.Vert( x, math.sin( x ), 0 )
mesh.verts.append( vNew )

while x < math.pi:[INDENT] x += 0.1
vOld = vNew
vNew = NMesh.Vert( x, math.sin( x ), 0 )
mesh.verts.append( vNew )
mesh.addEdge( vOld, vNew )
NMesh.PutRaw( mesh, “SineWave”, 1 )
Blender.Redraw()
[/INDENT]Now do this:

  • Run the script using ALT-p.
  • Change the Window type to 3D View (its corresponding # icon is in the drop-down menu)You should see a sine wave.

But more importantly, this also serves as a basic introduction to how to perform a little Python scripting inside of Blender. More information at:
