What's wrong with this.......(Displaying a triangle)

OpenGL OpenGL: Basic Coding

  glBegin(GL_TRIANGLES);
  glVertex3f(0.0,  1.0,0.0);
  glVertex3f(0.0,  1.0, 00);
  glVertex3f(0.0,  3.0,0.0);

//Try this
glBegin(GL_TRIANGLES);
glVertex3f( 0.0, 1.0, 0.0 );
glVertec3f(-1.0, 0.0, 0.0);
// Note above line used to contain 00
// instead of 0.0 Picky, I dunno.
glVertex3f( 1.0, 0.0, 0.0);
glEnd();
// This should draw you a triangle.
// glVertex3f( float x, float y, float z );

These vertices are at the same location. It looks like a typo.

looks like it’s exactly what he is trying to do. Copy/paste from code. All vertices are aligned, and two are at the same position. You won’t see a triangle, but maybe a line if you’re lucky. Also be careful of the winding order.

try glDisable(GL_CULL_FACE); if you still can’t see a triangle
