Solarsystem - OpenGL demo of a simple solar system -------------------------------------------------- Jon McCormack, April 2004, email: jonmc AT csse.monash.edu.au Developed as part of the CSE3313 Computer Graphics Course Monash University, School of Computer Science and Software Engineering Clayton, Victoria, Australia. This program illustrates the use of inherited compound transforms in OpenGL. The solar system consists of: - a sun at the world coordinate origin - Earth orbiting the sun once per year - moon orbiting the Earth once every 28 days (for fans of the film 28 days latter!). The Earth also rotates around its own axis once per day (24 hours) and is slightly tilted off its axis The program also illustrates the following: - a "virtual trackball" for object manipulation (see trackball.h and trackball.c) - OpenGL Lighting (there are 2 lights in the program a white light and a blue light) - Double buffering - Z-buffering (hidden surface removal) - use of different transformations for 3D shapes and 2D text in one viewport * Compiling the program: ----------------------- The program contains 2 makefiles: 1 for Mac OS X (BSD Unix) and one for Linux/X Windows Makefile.MacOSX - Macintosh Makefile Makefile.Linux - Linux Makefile copy the Makefile appropriate for your system to Makefile and then type make to build the program. make clean will remove all intermediate files. * Running the program: --------------------- solarsystem (no command line arguements) Hold down the left mouse button and move the mouse to activate the virtual trackball and revolve the solar system around on the screen. The right mouse button brings up a menu with the following options: wireframe - toggle wireframe/solid display of planets lighting - turn OpenGL lighting on and off smooth shading - turn OpenGL smoothing on and off z-buffer - turn OpenGL z-buffering on and off orbit rings - turn the display or earth and moon orbit paths on and off In addition to the menu there are a number of key commands: z - zoom out (using gluPerspective) Z - zoom in (using gluPerspective) . - zoom out (by translating the camera away from the origin) . - zoom in (by translating the camera towards the origin) + - increase simulation time step (runs faster) - - decrease simulation time step (runs slower) t - reset simulation time step q - quit the program * Extensions: ------------ You might like to try to code the following extensions: - Add backface removal to speed up display - Modify the trackball interface so its rotation is not reset when menu commands are called - Add text labels for the sun, Earth and moon that follow the objects as they move - Add a star field as background objects - Add texturing of the objects for a more realistic display * Files: ------- Makefile.Linux - Makefile for Linux/X11 systems Makefile.MacOSX - Makefile for MacOS X systems README - This file bool.h - defines simple boolean type material.c - material, colour and light definitions material.h solarsystem.c - main solarsystem code text.c - utility routines for text display text.h trackball.c - virtual trackball interface trackball.h
