Introduction Quite often I see a question in a newsgroup or forum along the lines of:
Or you can calculate your own. If desired, call gluNurbsProperty to choose rendering values, such as the maximum size of lines or polygons that are used to render your NURBS object. Call gluNurbsCallback if you want to be notified when an error is encountered. Error checking may slightly degrade performance but is still highly recommended.
Start your curve or surface by calling gluBeginCurve or gluBeginSurface. Generate and render your curve or surface.
Call gluNurbsCurve or gluNurbsSurface at least once with the control points rational or nonrationalknot sequence, and order of the polynomial basis function for your NURBS object. Call gluEndCurve or gluEndSurface to complete the curve or surface.
Example renders a NURBS surface in the shape of a symmetrical hill with control points ranging from The basis function is a cubic B-spline, but the knot sequence is nonuniform, with a multiplicity of 4 at each endpoint, causing the basis function to behave like a Bezier curve in each direction.
The surface is lighted, with a dark gray diffuse reflection and white specular highlights. Figure shows the surface as a lit wireframe.Common Programming Interface Communications Reference describes Systems Application Architecture (SAA) Common Programming Interface (CPI) Communications in detail, including scenarios and individual routines.
It is intended for anyone writing an application program that communicates with another program using the APPC protocol. What OOP is NOT. As a first step I shall debunk some of the answers that I have seen.
In compiling the following list I picked out those descriptions which are not actually unique to OOP as those features which already exist in non-OO languages cannot be used to differentiate between the two.
