Hi
I am new to opengl and i am trying to draw a triangle on the ZY plane. I am using gluLookAt to view my model but i am seeing only part of it. Everytime i put a value greater than 1 in the eye coordinates i get a black screen. Please help!!!
Here are my codes:
include <iostream>
include <GL/glut.h>
using namespace std;
void draw()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
gluLookAt(1.0,0.0,0.0,0.0,0.0,0.0,0.0,1.0,0.0);
glBegin(GL_TRIANGLES);
glVertex3f(0.0,0.0,0.0);
glVertex3f(0.0,2.0,2.0);
glVertex3f(0.0,0.0,4.0);
glEnd();
glutSwapBuffers();
}
int main(int argc, char **argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_RGB|GLUT_DEPTH);
glutInitWindowSize(400,400);
glutCreateWindow(“Theory”);
glutDisplayFunc(draw);
glutMainLoop();
return 0;
}
