Description

An opengl + glut application that performs the following transformations to a polygon in 3D:

  • scaling
  • rotate
  • translation

Note

This program uses a function coded by Michael Wainer for loading PPM's, fetched from http://www2.cs.siu.edu/~wainer/585S00/CUBE/cubedemo.html

Dependencies

  • Glut
  • OpenGL
  • libsdl1.2-dev

How to compile and run

make
./opengl-basics

How to use

  • Move camera
    • With the keypad:
      • '8' - moves camera up
      • '2' - moves camera down
      • '5' - zooms camera
      • '0' - unzoom camera
      • '4' - moves camera to left
      • '6' - moves camera to right
  • Translating
    • P sets translating unit to positive (0.5 units)
    • P sets translating unit to negative (-0.5 units)
    • CTRL + Y, translates in Y
    • CTRL + X, translates in X
    • CTRL + Z, translates in Z
  • Rotating
    • P sets rotating unit to positive (0.02 units)
    • P sets rotating unit to negative (-0.02 units)
    • ALT + Y, rotates in Y axis
    • ALT + X, rotates in X axis
    • ALT + Z, rotates in Z axis
  • Scaling
    • P sets scaling unit to positive (0.02 units)
    • P sets scaling unit to negative (-0.02 units)
    • SHIFT + Y, scales in Y axis
    • SHIFT + X, scales in X axis
    • SHIFT + Z, scales in Z axis
  • Increasing and decreasing transformation unit size
    • '+' increases transformation unit by 100% of the base unit (0.5 in case of translating, 0.02 in rotating and scaling)
    • '-' decreases transformation unit by 100% of the base unit (0.5 in case of translating, 0.02 in rotating and scaling)
