Problems with intersecting 3D openGL planes.

I have two 3D openGL planes, which are intersecting. From one positions they are painted correctly:

But when I rotate my chart line by which theese planes intersect becomes ugly painted:

Is it disadvantage of your software of maybe I can improve this situation?
If first, when are you going to fix this problem?

Here my chart and openGL settings:

Thank you.

Hi bairog,

I could reproduce the issue here and I'd say it is a TeeChart bug. I've added it (TF02011957) to our defect list to be reviewed for future releases.

I've discovered some other troubles with my chart described above:

1)I have a checkbox to determine is it necessary to draw one of those planes. The following code doesn't work (plane is always painted):

Code: Select all

surface1.Brush.Visible = checkbox1.Checked;

In orthogonal non-openGLchart it works correctly.

2)After several manipulations with my chart (switching between orthogonal non-openGL and openGL modes, making it invisible and visible again) I've got bottom wall ugly painted though it's Tansparent property is set to true:

Hi bairog,

1. I could reproduce the issue here and added it (TF02011966) to our defect list to be fixed for future releases.

2. I couldn't reproduce the problem here. Could you please send us a simple example project we can run "as-is" to reproduce the problem here?

Thanks in advance.
