Opengl 2 Work -

#include <GL/glut.h> void display() GL_DEPTH_BUFFER_BIT);

glutSwapBuffers();

Here’s a minimal working example in C (GLUT/FreeGLUT): opengl 2

glMatrixMode(GL_MODELVIEW); glLoadIdentity(); gluLookAt(0, 2, 5, 0, 0, 0, 0, 1, 0); #include &lt;GL/glut

Diving back into OpenGL 2 – the fixed-function nostalgia void display() GL_DEPTH_BUFFER_BIT)

glBegin(GL_TRIANGLES); glColor3f(1,0,0); glVertex3f(-1,-1,0); glColor3f(0,1,0); glVertex3f( 1,-1,0); glColor3f(0,0,1); glVertex3f( 0, 1,0); glEnd();

int main(int argc, char** argv) glutInit(&argc, argv); glutInitDisplayMode(GLUT_DOUBLE
