2. MPI Lab05 - Matrix multiplication Part 1, Row major form

3. MPI Lab05 - Matrix multiplication Part 2, Column major

4. MPI Lab05 - Matrix multiplication Part 3, Sending groups of consecutive columns

5. Reading: MPI Worksheet 4 (Chap 4), MPI Worksheet 5 (Chap 6) from WebCT-HPC
6. Trajectory Program - Introduction to Computer Graphics Modeling
   - see Computer Simulation and Modeling: "Project 1 - 3 Trajectory"

7. Help/Example programs (compile with "Lgcc progname" - no ".c")
   - Lgcc script (C) (don't forget to "chmod 755 Lgcc" to make this executable)
   - Lg++ script (C++) (don't forget to "chmod 755 Lg++" to make this executable)
   First: Run hello.c, Example 1-2 in Chapter 1 (see below)
   Also see: double.c, Example 1-3, using double buffering for animation
   and use of glutMouseFunc(mouse) - a callback function
   - GLUT API
   - GL and GLU
   - OpenGL Programming Guide
   - OpenGL Reference Guide
   - OpenGL.org
   • Basic starter programs
     • graph1.c (Draws a basic parabola: 4x - 4x^2 + 50)
     • graph2.c (Draws a basic parabola: 4x - 4x^2 + 50, uses e/x/d/s to move parabola, ESC to quit)
     • graph3.c (Draws a basic parabola: 4x - 4x^2 + 50, uses arrow keys to move parabola, ESC to quit)
     • "Commented version" of basicwindow.c
     • basicwindow.c, using text, and using mouse and keyboard routines
     • 2D simple animation: Animated parabola and squares
     • 3D simple animation + Adding a menu

8. OpenGL Programming Guide, Version 1.4
   • Chapter 1 (html)
     • Color Plates - from Appendix I, look through all plates, 1-38, read descriptions
     • OpenGL Command Syntax: commands begin with "gl", "glu", or "glut" depending on the library
       Ex. glClearColor(), glColor3f(), glVertex3f() - What does "3f" represent?
     • OpenGL datatypes: GLbyte, GLshort, GLint, GLdouble, etc., see Table 1-1
     • "v" is added for vectors:
       glColor3f(1.0, 0.0, 0.0);
       GLfloat color_array[] = {1.0, 0.0, 0.0};
       glColor3fv(color_array);
     • Libraries and include files:
       #include <GL/gl.h>
       #include <GL/glu.h>
       #include <GL/glut.h>
     • GLUT Window Management
       glutInit(), glutInitDisplayMode()
       glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH)
       glutInitWindowPosition(), glutInitWindowSize(), glutCreateWindow()
     • The Display Callback: glutDisplayFunc(void (*func)(void)),
       glutPostRedisplay(void)
     • Running the Program: glutMainLoop(void)
   • Basic starter programs
     • "Commented version" of basicwindow.c
     • basicwindow.c, using text, and using mouse and keyboard routines
     • 2D simple animation: Animated parabola and squares
     • 3D simple animation + Adding a menu
   • List of colours and RGB values
   • Handy mathematics Facts for Graphics - includes an approximation of PI to 35 decimal points.
   • Helpful OpenGL Online Resource Links
   • Programs from the OpenGL text
