A simple recursive raytracer with Phong-shading.
- Python 3
- Pillow
- PIL
- NumPy
Simply run python3 render.py. Will render the scene as a JPEG image.
Available arguments:
-res=WIDTH,HEIGHT: set the resolution of the output image
-quality=: set the quality of the output image; default value is 75
-ftype=STR: set the file type of the output image; default value is JPEG; for a list of supported filetypes please refer to PIL.Image documentation
-dirout=PATH: set the directory of the output image
-processes=INT: set the number of parallel running processes for multicore performance
-noshow: set, to not display the image after succesful renderering process
-export: set, to not display the image after succesful renderering process
-reflection=FLOAT: set the reflectiveness of materials; best results can be achieved when staying in the range of 0.1 to 0.5
-rdepth=INT: set the maximum recursion depth for tracing reflected rays
-lightintensity=INT: set the intensity of the light source
-lightpos=[X,Y,Z]: a vector with the coordinates of the light source
-lightcolor=(RGB)|<color-name>: the rgb color value of the light source
-spherecolors=(<color-left>,<color-top>,<color-right>): set the colors for each sphere
-floormat=[(RGB),AMBIENT,DIFFUSE,SPECULAR]|[MATERIAL]: set the material for the floor
- RGB: a rgb color value
- AMBIENT: float from 0.0 to 1.0
- DIFFUSE: float from 0.0 to 1.0
- SPECULAR: float from 0.0 to 1.0
If you are interested in what these values AMBIENT, DIFFUSE and SPECULAR mean and do please refer to the Phong-Shading wiki.
