Waterfall Display

jmsbc1

Hello,

Sorry I needed help in figuring out how to create a "waterfall display". It basically takes in a 2 dimensional array of 8bit pixels and displays it streaming down the screen. This data is just 8bit pixels and keeps streaming down my display (1600x1200).

I've implemented this using QT but it the PaintEvent() which gets called to refresh the image each time is too slow in scrolling the data down the screen.

I was wondering would the best solution be to generate a texture out of the 8bit pixels using opengl? Also, would I need to generate multiple textures of each line of data that comes in?

Or can somebody please help me figure out what's the best solution?

Thank you!!
