# Raymarch Engine (WIP)
A game engine that renders primitive objects by utilizing raymarching. Different operations can be applied to the
primitives to create more complex objects. The engine uses `SharpDX` as its `DirectX`
wrapper and `System.Numerics.Vectors` for Vectors, Quaternions and Matrices.
Raymarch shader code is located [here](Shaders/Raymarch/Pixel.hlsl).
## Live rendering preview
### Things to look for:
- The preview has four different primitives (octahedron, box, sphere, plane). And one light source.
- All objects cast and receive shadows. These are fully dynamic.
- Octahedron, sphere and plane have reflections.
- All objects have Blinn–Phong shading as a base.
- The octahedron has subsurface scattering. light penetrates its thin edges, making them appear lighter.
- The box has rounded corners as a result of a rounding operation being applied to it.
- There is ambient occlusion and blue noise applied to the view space.
- Some purple-ish distance fog is visible in the background.
- Raymarched objects have infinite resolution (signed distance function = no mesh).
## Requirements:
- .NET Framework 4.8
- C# 7.3+
- DirectX 11
- Shader Model 5 support
- A capable GPU
## Supported primitives:
- Sphere
- Box
- Plane
- Torus
- Capped torus
- Ellipsoid
- Capsule
- Hex prism
- Cone
- Cylinder
- Pyramid
- Octahedron
- Rhombus
## Supported operations:
+ Rounding
+ Infinite repetition
+ Union
+ Subtraction
+ Intersection
+ Onion slicing
