BrianMacIntosh / RasterLineIterator.cs

Created November 3, 2013 21:37

This class provides a mechanism to iterate through the pixels in a rasterized line. The pixels are returned in order by distance from the point 'start'. The iterator acts like a raycast, not like e.g. Bresenham's line algorithm, in that it returns every pixel intersected by the ray.

Last active December 29, 2015 07:19

Calculate the GCD (greatest common denominator) of two integers using the Euclidean algorithm. Recursive or iterative functions.

	//Helper fn
	int pgcdr(int a, int b)
	{
	if (a) return pgcdr(b % a, a);
	else return b;
	}

	//Recursive gcd fn
	int gcdr(int a, int b)

BrianMacIntosh / DegreesRadians.cs

Last active August 9, 2017 16:49

Shows how type-safe, automatically-converted degree and radian types could be created in C#.

	using System;

	class Program
	{
	static void Main(string[] args)
	{
	AngleDegrees angleA = new AngleDegrees(90);
	AngleRadians angleB = new AngleRadians(Math.PI / 2);

	// angleA will be implicitly converted to AngleRadians because that's what the method parameter is
