Compilation Option

All these defines are listed in main.cpp at the begining of the file, right after includes.

Cube vs Triangle

#define DRAW_CUBE_INSTEAD_OF_A_TRIANGLE 1

When this flag is set to 1, the program is compiled with rotating Cube in the middle of the window. If USE_OLD_RENDERER is set to 1, it's rendered as plainly white. it changes its color (more about it later). When this flag is set to 0, the program is compiles with rotating Triangle in the middle of the window. Any other value is invalid.

OpenGL 2.1- vs OpenGL 3.0+

#define USE_OLD_RENDERER 0

When this flag is set to 1, the program is compiled for OpenGL 2.1 or lower. In this mode it doesn't use shaders. When this flag is set to 0, the program is compiled for OpenGL 3.0 or newer. In this mode it does use shaders (located in resources folder). Any other value is invalid.

Window Number

#define WIN_COUNT 1

This flag defines the amount of windows program will create. Closing any of it will lead to termination of the program. If USE_OLD_RENDERER is set to 1, any number between 1 and 3 is allowed, otherwise - only 1 and this is statically asserted. Any other value is invalid.

Predefined Controls

General

  • Escape - close the program.

Camera Movements (TODO)

  • W - forward
  • A - left
  • S - backwards
  • D - right
  • Mouse movements - rotation
  • Mouse scroll - zoom

Color Change

  • C - switch between constant color change and one random color
  • Q - if constant color change is off, will paint the cube in random color.
