GLE-based extrusion node-types

Classes

class GLEGeom( GeometryNode ):
Base class for GLE geometry types
Provides the common operations and data seen in the GLE geometry types.
Attributes: textureMode -- specification of texture-coordinate generation mode to be passed to GLE, include: "mod" -- if present, use model view coordinates "ver"/"norm" -- vertex/normal mode "flat"/"cyl"/"sphere" -- flat, cylinder or spherical coordinate generation See: http://pyopengl.sourceforge.net/documentation/manual/gleTextureMode.3GLE.xml for semantics of the various modes.
sides
exposedField SFInt32 sides 32
textureMode
exposedField SFString textureMode
compile( self , mode = None )
Compile the geometry as a display-list
do( self )
Do the low-level rendering
render( self , visible = 1 , lit = 1 , textured = 1 , transparent = 0 , mode = None )
Render the geometry
class Lathe( GLEGeom ):
Lathe of contour around a spiral (or circle)
contour
