Based on the paper "Steering Behaviors For Autonomous Characters" by Craig W. Reynolds, this program implements three of the steering behaviors described therein: seek with arrival, wander with collision avoidance, and path following. Use the right arrow key to cycle through the behaviors and the ON key to quit. For the ARM-based calculators only.
Three more steering behaviors animations. Cycle through them with the right arrow key and quit with the ON key. You can freeze the screen with the left arrow key, and press the down down key to go on. For the ARM-based calculators.
Draws a version of the Sierpinski carpet, a version of the Sierpinski triangle, the Mandelbrot set,
and a Julia set at a resolution of 0.01. For the 50g.
A sat solver. It tries to find an assignment of values to the variables of a Boolean formula in CNF such that all the constraints are satisfied. Written in C for the 50g only.
The program takes a string representing a PGM file (Unix image format) from the stack and displays it in 16 levels of gray. Written in C for the ARM-based calculators.
Displays squares moving across the screen. The quantity, direction, speed, and frequency of direction change of the squares can be changed in the code, and there are both black on white and white on black versions. For large-screen calculators only (49g+ and 50g).
Demo written in assembly language that draws points moving around in circles.
Draws a version of the Sierpinski carpet, a version of the Sierpinski triangle, the Mandelbrot set,
and a Julia set at a resolution of 0.01. For the 50g.
A sat solver. It tries to find an assignment of values to the variables of a Boolean formula in CNF such that all the constraints are satisfied. Written in C for the 50g only.
You are in a maze and must find your way out.
Displays a message along a moving curve.
Converts grayscale PGM images to dithered monochrome GROBs using the Floyd-Steinberg algorithm. Includes sample images.
Turns a grob on the stack or the current display into a jigsaw puzzle. For the 50g.
This program reads the stack for as many successive grobs as can fit in memory, and then makes a slideshow crossfading between them.
Displays squares moving across the screen. The quantity, direction, speed, and frequency of direction change of the squares can be changed in the code, and there are both black on white and white on black versions. For large-screen calculators only (49g+ and 50g).
A stars screensaver for the large screen models (49g+ and 50g). Includes both Saturn assembly and ARM-compiled C versions.
This is a Sudoku player, for the ARM-based calculators only.
