 ### RAYMAX
 
-Rust implementation of a ray-tracer.
+Rust implementation of a ray-tracer and path-tracer.
+
+Features:
+ - ray-tracing + path-tracing
+ - parallelism with rayon
+ - allow the use of OBJ mesh objects
+ - material: kd/ke/ks
+ - light sources
+ - antialiasing
+ - bugs!
+
+It can run with a user-interface (egui), or via command line interface.
 
 ## Scenes

  - the definition of the light sources
  - the definition of each material kd/ke/ks used throughout the scene
- - the position of each infinite-plane, sphere or triangle if any,
+ - the position of each infinite-plane, sphere or triangle if any
  - a pointer to a 3D mesh object stored in OBJ format
  - the resolution of the resulting picture
