spining a cube w/ lighting in C++

[tupac]

k, so ive picked up again w/ openGL in c++ and learned some neat stuff i wana share w/ you.
today i'm going to show you how to create a window in c++ using GLUT, plus i'm going to show you how to create a cube that will spin on an axis and be lit by lighting provided with the GLUT library.
if you are using Dev-C++, download glut from here: http://www.nigels.com/glt/devpak/ click on: glut.3.7.6+.DevPak and install it. then open your Dev-C++, click on File->New->Project->Multimedia->glut. you will get a text file with stuff written on it, select it all and delete.

type the following in:

code:

//some simple header files that are needed #include <GL/gl.h> #include <GL/glut.h> GLfloat angle = 0; //for reshaping the window void reshape(int w, int h){      //Set a view port, and make w and h into floats that openGL understands      glViewport(0,0,(GLsizei)w,(GLsizei)h);      glMatrixMode(GL_PROJECTION);      glLoadIdentity();      gluPerspective(60,(GLsizei)w/(GLsizei)h,1.0,100.0);      glMatrixMode(GL_MODELVIEW); } void InitLight(){      glEnable(GL_DEPTH_TEST); //Tests the depth of space      glEnable(GL_LIGHTING); //turns the "lights" on      glEnable(GL_LIGHT0); //allows light #0 out of about 8 lights to shine      glEnable(GL_COLOR_MATERIAL); //allows color to appear when object is lit } void cube(){      glColor3f(1.0,0.0,0.0); //sets the color of the cube to red      glRotatef(angle,1.0,1.0,1.0); //rotates the cube      glutSolidCube(2); //draws the cube } //then we need to display something on the window we want to create void display(void){      glClearDepth(1); //clears the depth      glClearColor(0.0,0.0,0.0,1.0);//clears the window color to black      glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);      glLoadIdentity(); //loads matrix identity      gluLookAt(0.0,0.0,5.0,0.0,0.0,0.0,0.0,1.0,0.0); //sets where camera looks      cube(); //displays the cube function      glutSwapBuffers(); //switches between 1st and 2nd buffers      glFlush(); //flushes everything onto the screen      angle++;      if (angle>=360){ //this is checked in case that the float gets too big for c++ to handle, therefore preventing a crash           angle = 0;      } } int main(int argc, char *argv[]){ //type this if using Dev-C++ int main(int argc, char** argv){ // type this if using MSVC++      glutInit(&argc,argv); //initializes argc and argv's      glutInitDisplayMode (GL_DOUBLE | GL_RGBA | GL_DEPTH);//tells openGL to display double buffers, RedGreenBlueAlpha, and depth of light      glutInitWindowSize(500,500);//sets window size to 500pixels by 500pixels      glutInitWindowPosition(0,0);//sets the window to top left of screen      glutCreateWindow("Spinning Cube");//sets a caption on the window      InitLight();//turns on the "lights"      //the next three are a little obvious      glutDisplayFunc(display);      glutIdleFunc(display);//since the cube is gonna be moving, openGL needs to change whats going on in the program, so it will use Idle      glutReshapeFunc(reshape);      glutMainLoop();      return 0; }

Now this code should work, i can't tell if i missed some small detail because i'm writing from a library computer (its the only place i can use the internet from so far) and it doesnt have c++ on it, so i cant compile my prog and see if something is wrong with it. well, if somethings wrong w/ it just reply with any questions.

code:

int main(int argc, char *argv[]){ //type this if using Dev-C++ int main(int argc, char** argv){ // type this if using MSVC++

These are functionally identical.

o... well iduno but for some reason Dev-C++ (may-b just mine) doesnt want to run "int main(int argc, char** argv)" but works when i put "int main(int argc, char *argv[])"
but w/e i guess if it works then thats good

It has been my experience, that Dev-C++ is a darn poor environment. Just use GCC straight up.

wow, ogl is so much nicer than d3d..
