a simple python raytracer implementation
- Lambertian diffuse
- Metals with fuzziness
- The classic checkerboard floor texture
- Emissive materials
- Optional denoiser
- Live preview while rendering
- PPM file output
- Miserable performance (slow af)
To create your own renders: Modify samples, resolution, maxBounces and ambient occlusion in "src/main.py" and add objects to the scene by calling scene.addObject() and passing an object as a parameter.
To denoise a render: Run "denoiser/denoise.py", choose the input file in the first filedialogue and choose the output folder in the second.
| Folder | content |
|---|---|
| results/ | All of my renders (even those from older more primitive versions of the raytracer) |
| └ results/denoised | Denoised versions of some of the renders |
| └ results/fails | Funny failed renders luckily i dont have many of those.. or sadly |
| output.ppm | Default location for the resulting image file of a render (also overwriting old ones!) |
| src/ | This is where the code resides |
| world.json | This is the file that stores all your scenes. You can choose which one to load using "--scene" (defaults to scene1). |
| requirements.txt | All required librarys. Use "pip install -r requirements.txt" to install them |
| ARG | Action |
|---|---|
| -h, --help | show all possible args in a help message |
| --scene SCENE, -S SCENE, -scn SCENE | Load a scene from world.json. Input needs to be a valid name |
| --samples SAMPLES, -s SAMPLES, -smp SAMPLES | Number of samples per pixel |
| --bounces BOUNCES, -b BOUNCES, -bnc BOUNCES | Ray bounce cap |
| --resolution RESOLUTION, -r RESOLUTION, -res RESOLUTION | Image resolution as WIDTHxHEIGHT (Bsp: "600x400") |
| --destination DESTINATION, -d DESTINATION, -dest DESTINATION | Path to the rendered image |
