okayy...this is really strange... theres problem in the y axis... when i draw a point at (0,10,0) , i see the output at (0,-10,0) idk wats the prob plz help heres the sc
#include<windows.h>
#include<gl/glut.h>
void RenderScene()
{
glClear(GL_COLOR_BUFFER_BIT);
glColor3f(0,0,0);
glPointSize(5);
glBegin(GL_POINTS);
glVertex3f(0.0f,-70.0f,0.0f);
glEnd();
glFlush();
}
void SetMyScene()
{
glClearColor(1,1,1,1);
}
void Reshape(GLsizei w,GLsizei h)
{
if(h==0)
h=1;
glViewport(0,0,w,h);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
GLfloat ar=(GLfloat)w/(GLfloat)h;
if(w<=h)
glOrtho(-100,100,100/ar,-100/ar,1,-1);
else
glOrtho(-100*ar,100*ar,100,-100,1,-1);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
}

glutDisplayFunc(RenderScene);
glutReshapeFunc(Reshape);
SetMyScene();

return 0;
