Separable Subsurface Scattering Demo

Implementation of the Separable Subsurface Scattering technique from http://www.iryoku.com/separable-sss/ in C++ and Vulkan 1.0. Additionally this demo features physically-based shading, image-based lighting, shadow mapping and temporal anti-aliasing.

Controls

• Right click + mouse rotates the camera.
• Mouse scroll wheel zooms in and out.
• A GUI window offers additional options such as toggling SSS or TAA, changing window resolution or adjusting the light position.

Requirements

• Vulkan 1.0
• 256 MB RAM
• 1 GB video memory

How to build

The project comes as a Visual Studio 2017 solution and already includes all dependencies. The Application can be build as both x86 and x64.
