Probleme with VBO and 2 GlControls on the same form #7

Closed FrancisMartin-VB closed 3 years ago

FrancisMartin-VB commented 3 years ago

Hello, I'm trying to run a Framework 4.8 project that works fine in Net.5. I have a VBO which is posted on 2 GLcontrols. In 5.0 impossible to display the VBO on the control added in 2nd on the form while the basic commands are well displayed. I created a 2nd VBO, a 2nd Shader but it didn't change anything. Have you ever encountered this problem and how to fix it? Sincerely, Francis

I suspect this is about the OpenGL context: When you create the GLControls, are you assigning them the same SharedContext? If they don't share an OpenGL context, they won't be able to share data either.

Hello, Thank you for your reply. Effectively each control in its context. So I recreated the VBOs for each of them and it works great now. cordially
