white_dune 0.29beta953 (Development branch)
Image white_dune is a graphical VRML97 editor, simple NURBS/Superformula 3D modeller and animation tool. VRML97 (Virtual Reality Modeling Language) is the ISO standard for displaying 3D data over the Web via browser plugins ("HTML for realtime 3D"). It has support for animation, real-time interaction, and multimedia (images, movies, and sounds). white_dune can read, create and display VRML97 files and let the user change the scenegraph/fields. It also has support for stereoscopic view via "quadbuffer"-capable stereo visuals, and support for 3D input devices like a joystick, spaceball, or magnetic tracker.

A parser error for X3DV InputOutput fields in PROTOs was fixed. LabView Covise/COVER plugin extension node was added.Image

glubegincurve

GLUBEGINCURVE(3G)														 GLUBEGINCURVE(3G)

NAME

       gluBeginCurve, gluEndCurve - delimit a NURBS curve definition

C SPECIFICATION

       void gluBeginCurve( GLUnurbs* nurb )

       void gluEndCurve( GLUnurbs* nurb )

PARAMETERS

       nurb  Specifies the NURBS object (created with gluNewNurbsRenderer).

DESCRIPTION

       Use  gluBeginCurve to mark the beginning of a NURBS curve definition.  After calling gluBeginCurve, make one or more calls to gluNurbsCurve
       to define the attributes of the curve.  Exactly one of  the  calls  to  gluNurbsCurve  must  have  a  curve  type  of  GL_MAP1_VERTEX_3	or
       GL_MAP1_VERTEX_4.  To mark the end of the NURBS curve definition, call gluEndCurve.

       GL  evaluators  are  used  to  render  the  NURBS  curve  as a series of line segments.	Evaluator state is preserved during rendering with
       glPushAttrib(GL_EVAL_BIT) and glPopAttrib().  See the glPushAttrib reference page for details on exactly what state these calls preserve.

EXAMPLE

       The following commands render a textured NURBS curve with normals; texture coordinates and normals are also specified as NURBS curves:

       gluBeginCurve(nobj);
	  gluNurbsCurve(nobj, ..., GL_MAP1_TEXTURE_COORD_2);
	  gluNurbsCurve(nobj, ..., GL_MAP1_NORMAL);
	  gluNurbsCurve(nobj, ..., GL_MAP1_VERTEX_4); gluEndCurve(nobj);
