Firstly, I installed three lib of opengl as follow, sudo apt-get install freeglut3_dev sudo apt-get install libxi-dev sudo apt-get install libxmu-dev Then I created one simple c code Code: #include <GL/glut.h> #include <stdlib.h> #include <stdio.h> void init(void) { GLfloat mat_specular[]={1.0,1.0,1.0,1.0}; GLfloat mat_shininess[]={50.0}; GLfloat light_position[]={1.0,1.0,1.0,1.0}; glClearColor(0.0,0.0,0.0,0.0); glShadeModel(GL_SMOOTH); glMaterialfv(GL_FRONT,GL_SPECULAR,mat_specular); glMaterialfv(GL_FRONT,GL_SHININESS,mat_shininess); glLightfv(GL_LIGHT0,GL_POSITION,light_position); glEnable(GL_LIGHTING); glEnable(GL_LIGHT0); glEnable(GL_DEPTH_TEST); } void display(void) { glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT); glutSolidSphere(1.0,40,50); glFlush(); } void reshape(int w,int h) { glViewport(0,0,(GLsizei)w,(GLsizei)h); glMatrixMode(GL_PROJECTION); glLoadIdentity(); if(w<=h) glOrtho(-1.5,1.5,-1.5*(GLfloat)h/(GLfloat)w,1.5*(GLfloat)h/(GLfloat)w,-10.0,10.0); else glOrtho(-1.5*(GLfloat)h/(GLfloat)w,1.5*(GLfloat)h/(GLfloat)w,-1.5,1.5,-10.0,10.0); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); } void keyboard(unsigned char key,int x,int y) { switch(key) { case 27: exit(0); break; } } void main(int argc,char ** argv) { printf("Compiled: "__DATE__" at "__TIME__"\n"); glutInit(&argc,argv); glutInitDisplayMode(GLUT_SINGLE|GLUT_RGB|GLUT_DEPTH); glutInitWindowSize(300,300); glutInitWindowPosition(100,100); glutCreateWindow(argv[0]); init(); glutDisplayFunc(display); glutReshapeFunc(reshape); glutKeyboardFunc(keyboard); glutMainLoop(); } and, I compiled it via gcc , sudo gcc light.c -o light -lGL -lglut The udoo system cannot work as well as the other real ubuntu sytem, can you tell me?
UDOO (like most other embedded systems) supports only OpenGL ES 2/3, a subset of OpenGL. The headers can be installed from the imx-gpu-viv-9t6-dev package.
ok, I have install the package already now. If I use it , can you show one example code for draw on opengl es! Thanks!
I'm sorry, I have never written OpenGL code. You can try to search on google "linux opengl example". You can start from here.
