Today, we are excited to introduce you to the new additions to the FidelityFX family. As many of you will know already, FidelityFX was announced last year with the first of our open source effects, Contrast Adaptive Sharpening (CAS). Since then we’ve been absolutely delighted to see the community embrace CAS and FidelityFX.
That’s why we are now expanding our FidelityFX family with four new members: Stochastic Screen Space Reflections (SSSR), Combined Adaptive Compute Ambient Occlusion (CACAO), Luminance Preserving Mapper (LPM), and Single Pass Downsampler (SPD).
Mirror, mirror on the wall.... Who's got open source reflections for all?
That would be us! The first of our four new FidelityFX effects is Stochastic Screen Space Reflections (SSSR). This is our implementation of the ever popular Screen Space Reflections technique. This effect can create realistic looking reflections, purely based on information already present in the rendered image. Check out the SSSR page for more details.
Sweet like chocolate
FidelityFX CACAO stands for Combined Adaptive Compute Ambient Occlusion and is based on Intel®’s Adaptive Screen Space Ambient Occlusion, however our team has been busy tinkering and optimizing it. First of all, we moved the entire thing over to compute, allowing you the freedom to run it on either a compute or graphics queue. We’ve also done some major surgery on the data-transformations the effect undertakes. Finally, we also included an upsampler option to allow you to get high quality ambient occlusion within a budget that suits your game.
Look for the light!
Ensure all that effort you put into lighting and shading your scenes is nicely carried through to the screen. FidelityFX LPM (Luminance Preserving Mapper) provides fast and easy-to-integrate HDR and wide gamut tone and gamut mapping for your game.
Almost every game will need to downsample something at some point. Perhaps you’re moving a buffer to a lower resolution for performance reasons, or maybe you’re generating a MIPmap chain. The standard way of doing this is simple, but potentially introduces lots of bubbles into the graphics pipeline. Pop those bubbles by using FidelityFX SPD, our Single Pass Downsampler that can generate up to 12 MIPmap levels in a single compute shader pass.
And if you haven’t already checked out FidelityFX CAS, then now is a good time. CAS provides a mixed ability to sharpen and optionally scale an image. Take a look at what game developers have been already saying about FidelityFX CAS.
