Raytracer. A hot topic on the ATARI. With ARROW, the way into three-dimensional space is open. Objects can be easily designed in the comfortable 3D editor, scenes can be put together, light sources can be defined and then transformed into an image in 24-bit quality with the raytracer. The screen display is converted into the respective existing color resolution, whether 256, 16 colors or monochrome. 3D editor: 1-sided, 4-sided and vanishing point display, predefined figures (spheres, ellipses, polygon and rotation bodies); surfaces: diffuse, specular, luminous. The raytracer generates images in IMG, TIFF, IFF, BMP format, can independently swap to disk/hard drive in case of memory shortage, works in the background with MultiTOS and also supports an existing FPU.
