.net - Drawing Pixels in WPF

Question

how would I manage pixel-by-pixel rendering in WPF (like, say, for a raytracer)? My initial guess was to create a BitmapImage, modify the buffer, and display that in an Image control, but I couldn't figure out how to create one (the create method requires a block of unmanaged memory)

Answer 1

I highly recommend against the previous two suggestions. The WriteableBitmap class provides what you need assuming you are using 3.5 SP1. Before SP1 there's no really good answer to this question in WPF unless you resort to some serious trickery.
