Path Tracer Demo using Evergine

This is a toy path tracer demo used to show the Evergine raytracing common low-level API capabilities. In this demo, you can see how to implement a little room path tracer with Soft Shadow, Ambient Occlusion, Global Ilumination, and Antialiasing.

For more details about this demo read this article.

Build and Run

• Required Visual Studio 2022 with.NET6 support
• Required Graphics card with Raytracing technology (Ej. NVidia Geforce 2060 or higher)
• DirectX12 and Vulkan support. (Change in the program.cs or pass as arguments)

Parameters

The parameters available for manage the path tracer render are:

• Camera Pos X: Move the camera position in X-axis.
• Camera Pos Y: Move the camera position in Y-axis.
• Camera Pos Z: Move the camera position in Z-axis.
• Light Radius: Light radius affect the shadows.
• AO Num. Rays: Number of Ambient occlusion rays.
• AO Radius: Lenght of the ambient occlusion rays.
• GI Num Bounces: Number of bounces of Global illumination rays.
• Num Samples: Number of samples used to the path tracer render.

Compile Shader HLSL to SpirV

To compile HLSL (DX12) shader to SpirV (Vulkan) you can use the shaderTranslator.ps1 script in Content/Shaders folder.
