Z-Axis blocking my Graph Line/Data

OpenGL OpenGL: Basic Coding

Hey guys…

I can’t figure out why this is happening, but whenever I put up the QUADS/PLANES for the 3d-like walls, they “cover” or block out the data line…
I’m stuck :confused:

It’s giving me problems with attaching images/urls…

There is the result.

Thanks in advance

Do you have depth buffering enabled? Enable it thusly in your initialization section:

glEnable(GL_DEPTH);
glDepthFunc(GL_LESS);

And be sure you clear both the color buffer and the depth buffer in your render routine, or only the first render will be correct:

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

Depth buffering causes fragments with a lower depth buffer value to be “in front” of other fragments with higher depth buffer values, when using the GL_LESS depth buffering function.

Thanks for the quick response.

I have ensured that those bits of code are in the program.

This is the result…

The bottom view is okay, but not from the top.
