Ubuntu14.04 OpenGL Animation test Program

1 Installing the FREEGLUT3 OpenGL Auxiliary class Library

sudo apt-get install Freeglut3-dev

2 Compiling commands

GCC Test.cpp-lglut-lgl-lglu

As can be seen from the above command, three classes of libraries are used

3 Animation test Program

Third party libraries: sudo apt-get install freeglut3-dev//which uses the Glut.h file//compile command: GCC test.cpp-lglut-lgl-lglu#include <gl/   glut.h> #include <stdlib.h>static glfloat spin = 0.0;void display (void) {glclear (gl_color_buffer_bit);   Glpushmatrix ();   GLROTATEF (Spin, 0.0, 0.0, 1.0);   GLCOLOR3F (1.0, 1.0, 1.0);   GLRECTF (-25.0,-25.0, 25.0, 25.0);   Glpopmatrix (); Glutswapbuffers ();}   void Spindisplay (void) {spin = spin + 2.0;   if (Spin > 360.0) spin = spin-360.0; Glutpostredisplay ();}   void init (void) {Glclearcolor (0.0, 0.0, 0.0, 0.0); Glshademodel (Gl_flat);}   void reshape (int w, int h) {glviewport (0, 0, (Glsizei) W, (Glsizei) h);   Glmatrixmode (gl_projection);   Glloadidentity ();   Glortho (-50.0, 50.0,-50.0, 50.0,-1.0, 1.0);   Glmatrixmode (Gl_modelview); Glloadidentity ();} void Mouse (int button, int state, int x, int. y) {switch (button) {case Glut_left_button:if (state = = GLU         T_down) Glutidlefunc (Spindisplay);      BreakCase Glut_middle_button:case glut_right_button:if (state = = Glut_down) glutidlefunc (NULL);      Break   Default:break; }/* * Request double buffer display mode.   * Register Mouse Input callback functions */int main (int argc, char** argv) {glutinit (&AMP;ARGC, argv); Glutinitdisplaymode (glut_double |   GLUT_RGB);    Glutinitwindowsize (250, 250);   Glutinitwindowposition (100, 100);   Glutcreatewindow (Argv[0]);   Init ();    Glutdisplayfunc (display);    Glutreshapefunc (reshape);   Glutidlefunc (Spindisplay);   Glutmousefunc (mouse);   Glutmainloop ();   return 0; /* ANSI C requires main to return int. */}

Save as Test.cpp file and compile with command (2) to get a.out

4 run

./a.out

The result is a rotated rectangle animation.
