Why OpenGL do not supports overlay and underlay in Windows
Hi,
Sorry for my bad English, I need to develop an OpenGL application which need to layers of rendering. Means first layer will render some image to screen, and the same time other layer updated in background. ThreadDrawForeground() { renders some image. } ThreadDrawBackGround() { renders some image. } When I use same rendering context and cleared both frame buffers, causes flickering effect. Then I got an overlay and underlay concept in OpenGL. How can I use it. |
