Hi, Kevin Are you really need mesh? You can store data in image and draw just one quad textured with this image. Update data in image according to your input data -> draw quad, repeat. I think you can reuse some your code for mesh generation to create (point coordinates in image) -> (polar coords) pairs to easily access data in image
