by Glenn M. Lewis
Glenn presents a C++ morphing program that simulates a "melting" effect (and its reverse) on 3-D objects. The program, which compiles and runs on UNIX machines, PCs, and the Amiga, generates objects analogous to key frames in animation sequences.
by Robert Krten
Realistic landscapes are the bread and butter of computer graphics. Robert shares a technique he calls "fault-generation" for simulating mountains and other geological features found in nature--and it's fast!

Texture mapping allows you to project a 2-D image, or texture map, onto a flat polygon that has been placed on a 3-D surface. Jeremy's program draws a rotating cube (the model) painted with three different texture maps.
by Alain Mangen
Alain uses C++ inheritance to create RAY, a powerful ray-tracing program that performs hidden-surface removal and simulates shadow and semishadow effects to produce images of dazzling realism.
by Jack Woehr
In the first installment of this exclusive interview with Lotfi Zadeh, the father of fuzzy logic, Zadeh discusses the philosophical underpinnings of fuzzy logic, how it relates to fractals and AI, and his youth in the USSR and Iran.
by Douglas Reilly
Any application that depends upon accurate entry of data with little or no user intervention is a candidate for bar codes. The PCL class Doug presents here lets you create bar-code symbols on PCL-compatible laser printers.

Postman is an interface program that sits between an in-house, UNIX-based, personal-information system and the UNIX sendmail program. It provides a way to exchange mail between user-application programs and the outside world through the existing UNIX mail system.

The POV-Ray ("Persistence of Vision Ray Tracer") toolkit is a powerful, multiplatform package available free of charge in source-code and executable form for PCs (running under DOS, Windows, NT, or OS/2), Macintosh, Amiga, UNIX (including the X Window System), and VMS workstations.
by Dennis Cronin
Dennis implements DSP algorithms to create real-time audio effects--pitch change, echo, flanging, and phase shifting--for the Microsoft Windows Sound System.
by Michael Swaine
Michael wraps up his mushroom-identification programming project for the Newton MessagePad.
by Al Stevens
Al continues his presentation of the Quincy preprocessor, this month focusing on the parts that resolve #define macros and evaluate #if expressions.
by Tim Kientzle
The circle algorithm presented here is both fast and exact when plotting the closest points to the circle and drawing ellipses.

Ralf Brown examines the undocumented side of the private programming interface of QEMM, Quarterdeck's 386 memory manager.
by Jonathan Erickson
This month, we look at three books on graphics file formats--the Encyclopedia of Graphics File Formats, Bitmapped Graphics Programming in C++, and Programming for Graphics Files in C and C++.
