I have started developing my Application for Radar display and as suggested, I have gathered some info abt FBO as well.
Now I have a doubt. I want to draw a Circle, a pointer rotating along the circle and some info inside the Circle which may be some clouds or some Big dotts.
What I understand is I can create Circle and the pointer which roates on every timer expiry. And the cloud info if I draw every time then it would be bit slower and flicker. Now I draw the cloud info as Texture, how this updated texture will be refreshed on the screen at evry timer expiry.
As i am very new to OpenGL please help me in this.
Do you have any sample code or refernce which can help me in achiveing my objective, then please send.
Thanking in Advance.
