Question

i need help with my code for drawing a 3d cube
code is as follows

Answer 1

void display()
{
glClear(GL_COLOR_BUFFER_BIT);
glBegin(GL_LINE_STRIP);
glVertex2f(0.01,0.25);
glVertex2f(0.3,0.3);
glVertex2f(-0.13,0.3);
glVertex2f(-0.6,0.263);
glVertex2f(-0.654,-0.5);
glVertex2f(0.01,-0.5);
glVertex2f(0.3,-0.27);

glEnd();
glFlush();
}
void Color()
{
glClearColor(0.0, 0.0, 0.0, 0.0);
glColor3f(1.0, 1.0, 1.0);
}
int main(int argc, char** argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
glutInitWindowSize(500, 500);
glutInitWindowPosition(200, 100);
glutCreateWindow("cube");
glutDisplayFunc(display);
Color();
glutMainLoop();
return 0;
}

Answer 2

main problem here is that i dont know which one to use
glVertex2f(x,y);
or
glVertex2i(x,y);
or
glVertex3f(x,y,z);

Answer 3

secondly help me with co-ordinates

Answer 4

i figured it out myself

#include<GL/glut.h>
void display()
{
glClear(GL_COLOR_BUFFER_BIT);

glRotatef(30,1,1,1);
glBegin(GL_QUADS);
glColor3f(1,0,0);
glVertex3f(-0.5,-0.5,-0.5);
glVertex3f( 0.5,-0.5,-0.5);
glVertex3f( 0.5, 0.5,-0.5);
glVertex3f(-0.5, 0.5,-0.5);
glColor3f(0,1,0);
glVertex3f(-0.5,-0.5,-0.5);
glVertex3f(-0.5,-0.5, 0.5);
glVertex3f(-0.5, 0.5, 0.5);
glVertex3f(-0.5, 0.5,-0.5);
glColor3f(0,0,1);
glVertex3f( 0.5,-0.5, 0.5);
glVertex3f( 0.5,-0.5,-0.5);
glVertex3f( 0.5, 0.5,-0.5);
glVertex3f( 0.5, 0.5, 0.5);
glColor3f(1,1,0);
glVertex3f(-0.5,-0.5,-0.5);
glVertex3f( 0.5,-0.5,-0.5);
glVertex3f( 0.5,-0.5, 0.5);
glVertex3f(-0.5,-0.5, 0.5);
glColor3f(0,1,1);
glVertex3f(-0.5,-0.5, 0.5);
glVertex3f( 0.5,-0.5, 0.5);
glVertex3f( 0.5, 0.5, 0.5);
glVertex3f(-0.5, 0.5, 0.5);
glEnd();
glFlush();
}
void Color()
{
glClearColor(0.0, 0.0, 0.0, 0.0);
glColor3f(0.0, 1.0, 1.0);
}
int main(int argc, char** argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
glutInitWindowSize(500, 500);
glutInitWindowPosition(200, 100);
glutCreateWindow("cube");
glutDisplayFunc(display);
Color();
glutMainLoop();
return 0;
}

Answer 5

it'll make a cube like this.

Answer 6

*quite amused* I dont understand the letters and symbols up there tho. I just see how cool the cube is:)

Answer 7

yup its graphic designing :D

Answer 8

I only know how to kinda mix songs together:D i learned it!

Answer 9

awesome :D
