Based off of Sascha Willems' raytracingreflections demo code.

Supports:

• Reflection and refraction (Fresnel)
• Chromatic aberration
• Multiple shadow-casting lights
• Multiple textures
• Fast glossy (noisy) reflections
• Fast blurry (noisy) shadow edges
• Volumetric fog via ray marching/tracing
• Caustic refraction
• Large-format screenshots (may require a TDR time extension, if your framerate dips below 1 FPS, like on my 3060):

KeyPath : HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\GraphicsDrivers
KeyValue : TdrDelay
ValueType : REG_DWORD (32bit)
ValueData : Number of seconds to delay. 2 seconds is the default value.

Soon to support:

• Depth of field effects
• 3D texture lookup for custom volumetric effects (like, smoke from EmberGen).
• Caustic reflections
