Hi All

In glOrtho I'm drawing a line with 2 points (x, y, z)

(434, 500, 400)

(1190, 500, -1152)

But the line is not displayed. However if I change z in debugger (from -1152 to 400), then all is Ok, a horizontal line appears. Same results with glDrawArrays, glDrawArrays and just glBegin/glEnd

Any advice?

Thanks

Tom

I would guess, that your line is behind your orthogonal camera.

How do you have your projection matrix set up?

Hi All,

Solved, it was my mistake in bounding box calculation.!!

Thanks for your replies
