Description
A cube file, also known as a Cube Color Lookup Table, is a color palette file type used in the fields of 3D graphics and media production. It stores a 3D cube of color values which can be used to map colors in 3D images.
The PNM (Portable Any Map Image) file format is a subset of the broader Netpbm format, designed for storing various types of digital images. It acts as an umbrella term for three specific types of grayscale, color, and black-and-white images, represented by PBM (Portable Bitmap), PGM (Portable Graymap), and PPM (Portable Pixmap) formats respectively. PNM files are known for their simplicity and ease of conversion to other image formats.
