How to compile OpenGL Glut Glew program with CodeBlocks
These istructions are about setting the environment (compiler, libraries, etc.) to compile and execute OpenGL + Glut + Glew programs, with a final section about HW0 assignement of CS184.1x course on edX. They have been tested using CodeBlocks 10.05 on Windows 8 platform, but they should work on any flauvor of Windows. CodeBlocks is already able to compile OpenGL programs, but if you need to use Glut + Glew utility libraries you have to add these libraries to the system and modify the options of the project.
Steps to do:
This is an example
/* * GLUT Shapes Demo * * Written by Nigel Stewart November 2003 * * This program is test harness for the sphere, cone * and torus shapes in GLUT. * * Spinning wireframe and smooth shaded shapes are * displayed until the ESC or q key is pressed. The * number of geometry stacks and slices can be adjusted * using the + and - keys. */ #include#include static int slices = 16; static int stacks = 16; /* GLUT callback Handlers */ static void resize(int width, int height) { const float ar = (float) width / (float) height; glViewport(0, 0, width, height); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glFrustum(-ar, ar, -1.0, 1.0, 2.0, 100.0); glMatrixMode(GL_MODELVIEW); glLoadIdentity() ; } static void display(void) { const double t = glutGet(GLUT_ELAPSED_TIME) / 1000.0; const double a = t*90.0; glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glColor3d(1,0,0); glPushMatrix(); glTranslated(-2.4,1.2,-6); glRotated(60,1,0,0); glRotated(a,0,0,1); glutSolidSphere(1,slices,stacks); glPopMatrix(); glPushMatrix(); glTranslated(0,1.2,-6); glRotated(60,1,0,0); glRotated(a,0,0,1); glutSolidCone(1,1,slices,stacks); glPopMatrix(); glPushMatrix(); glTranslated(2.4,1.2,-6); glRotated(60,1,0,0); glRotated(a,0,0,1); glutSolidTorus(0.2,0.8,slices,stacks); glPopMatrix(); glPushMatrix(); glTranslated(-2.4,-1.2,-6); glRotated(60,1,0,0); glRotated(a,0,0,1); glutWireSphere(1,slices,stacks); glPopMatrix(); glPushMatrix(); glTranslated(0,-1.2,-6); glRotated(60,1,0,0); glRotated(a,0,0,1); glutWireCone(1,1,slices,stacks); glPopMatrix(); glPushMatrix(); glTranslated(2.4,-1.2,-6); glRotated(60,1,0,0); glRotated(a,0,0,1); glutWireTorus(0.2,0.8,slices,stacks); glPopMatrix(); glutSwapBuffers(); } static void key(unsigned char key, int x, int y) { switch (key) { case 27 : case 'q': exit(0); break; case '+': slices++; stacks++; break; case '-': if (slices>3 && stacks>3) { slices--; stacks--; } break; } glutPostRedisplay(); } static void idle(void) { glutPostRedisplay(); } const GLfloat light_ambient[] = { 0.0f, 0.0f, 0.0f, 1.0f }; const GLfloat light_diffuse[] = { 1.0f, 1.0f, 1.0f, 1.0f }; const GLfloat light_specular[] = { 1.0f, 1.0f, 1.0f, 1.0f }; const GLfloat light_position[] = { 2.0f, 5.0f, 5.0f, 0.0f }; const GLfloat mat_ambient[] = { 0.7f, 0.7f, 0.7f, 1.0f }; const GLfloat mat_diffuse[] = { 0.8f, 0.8f, 0.8f, 1.0f }; const GLfloat mat_specular[] = { 1.0f, 1.0f, 1.0f, 1.0f }; const GLfloat high_shininess[] = { 100.0f }; /* Program entry point */ int main(int argc, char *argv[]) { glutInit(&argc, argv); glutInitWindowSize(640,480); glutInitWindowPosition(10,10); glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH); glutCreateWindow("GLUT Shapes"); glutReshapeFunc(resize); glutDisplayFunc(display); glutKeyboardFunc(key); glutIdleFunc(idle); glClearColor(1,1,1,1); glEnable(GL_CULL_FACE); glCullFace(GL_BACK); glEnable(GL_DEPTH_TEST); glDepthFunc(GL_LESS); glEnable(GL_LIGHT0); glEnable(GL_NORMALIZE); glEnable(GL_COLOR_MATERIAL); glEnable(GL_LIGHTING); glLightfv(GL_LIGHT0, GL_AMBIENT, light_ambient); glLightfv(GL_LIGHT0, GL_DIFFUSE, light_diffuse); glLightfv(GL_LIGHT0, GL_SPECULAR, light_specular); glLightfv(GL_LIGHT0, GL_POSITION, light_position); glMaterialfv(GL_FRONT, GL_AMBIENT, mat_ambient); glMaterialfv(GL_FRONT, GL_DIFFUSE, mat_diffuse); glMaterialfv(GL_FRONT, GL_SPECULAR, mat_specular); glMaterialfv(GL_FRONT, GL_SHININESS, high_shininess); glutMainLoop(); return EXIT_SUCCESS; }
Now I'm attending the CS184.1x course (Foundation on Computer Graphics) on edX, so I need to compile some examples and assignements with CodeBlocks, but they are provided in Visual Studio format and it is not possible to import in an easy way. If you want to compile you need to set up your environmente as I explained above, then you have to download the Visual Studio HW0 assignement. Then extract all the contents of the folder hw0-windows inside the zip in your CodeBlocks project folder. Add the .cpp files to your project, eventually remove the main.cpp file from the template created by CodeBlocks. As the last step is necessary to copy the FreeImage.h in "
