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

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); SEE ALSO
