In plain words
Old School Graphics Algorithms is a collection of classic computer graphics techniques and implementations. It serves programmers and graphics enthusiasts interested in understanding foundational rendering methods and visual computing approaches. The resource provides practical algorithm implementations that demonstrate how older graphics systems solved computational problems before modern GPU acceleration became standard.

C++ Bitmap Library
The C++ Bitmap Library consists of simple, robust, optimized and portable processing routines for the 24-bit per pixel bitmap image format. Free use of the C++ Bitmap Library is permitted under the guidelines and in accordance with the MIT License. The following example will open a bitmap image called 'input.bmp' by instantiating an instance of the bitmap_image class and then proceed to count the number of pixels that have a red channel value greater than or equal to 111, then proceed to print the count to stdout. [Code: bitmap_simple_example01.cpp] The following example will create a bitmap of dimensions 200x200 pixels, set the background colour to orange, then proceed to draw a circle…from partow.net
