c++ - Gradients for polygons in OpenGL -


What is the best way to create a gradient for 2G polygon, (linear, and radial) in OpenGL?

Thanks

How can you create textures for Radial Gradient on the fly?

Linear is very easy - you set different colors such as different numbers

  red ---- red | | | | | | Blue for radial texture ---- blue  

may be a better option

Make empty texture to generate it on the fly and fill it with function sqrt ((MAXX - x) ^ 2 + (Maxy - Y) ^ 2), then add color to it.
