# [Lucifer]

> [Lucifer] is a CPU ray-tracer implemented in TypeScript for [Deno]. It is a

> direct translation of [raymancer], which is an earlier ray-tracer of mine

> written in Kotlin.

# Results

These images were generated with dimensions `512 x 512` pixels and decreasing

number of ray bounces (from 4 to 1). With fewer bounces, reflections become less

and less sophisticated.

![example with 3 bounces](output/d3-512.png)

![example with 1 bounces](output/d1-512.png)

# Future Work

This project is still very much work in progress and a lot could be improved:

- Add controls for image size and depth.

- Indicate rendering progress.

- Allow non-square images.

- Move rendering to service-worker.

- Optimize performance / move to GPU.

# That's it!
