Installation

pre-requisites

• OSX or Linux
• OpenGL/Glut
  • AskUbuntu compiling GLUT
  • GLUT how-to
• g++

$ git clone git@github.com:MrcRjs/OpenGl101.git
$ cd OpenGl101

Each practice has it's own makefile, by default it will compile all artifacts

$ cd practica1
$ make
$ ./basic.o

Contents

Practica 1

ejemplo1.cpp

Examples on how to use GL_POINTS, GL_LINES, GL_POLYGON, GL_TRIANGLE, GL_TRIANGLE_STRIP, GL_TRIANGLE_FAN, GL_QUADS, GL_QUAD_STRIP, GL_LINE_STRIP GL_LINE_LOOP.

Practica 2

actividades.cpp actividades-alt.cpp

Translation, rotation and scaling examples using own functions and OpenGL built-in glTranslate() glRotate() and glScale()

Practica 3

primitiveRobot.cpp

Graphing a drawing using only triangles, quadrilaterals and coordinates.

primitiveRobotFunctions.cpp

The character is separated into different parts to be drawn with separate functions.

Practica 4

menus.cpp menu.cpp menu_niveles.cpp
