StagPoint / SimplePathSmoother.cs

Last active June 17, 2022 10:59

Implements a simplistic 3D curve smoother for Unity. Depending on the intended use case, best results might be achieved by preprocessing the curve to have equally-spaced points, or using the Ramer-Douglas-Peucker algorithm to remove unnecessary points. It wasn't needed for my use case, so I didn't include that code here. YMMV.

StagPoint / Morton2D.cs

Last active May 6, 2024 15:45

Represents 2D Morton Codes by interleaving two 16-bit unsigned integer values into a 32-bit unsigned integer.

	// **************************************************
	// EXAMPLE USAGE:
	//
	// // Returns a single value with arguments x and y interleaved
	// var code = MortonCode2D.Interleave( 123, 456 );
	//
	// // Extracts the interleaved values (123 and 456) into integer variables x and y
	// MortonCode2D.Deinterleave( code, out int x, out int y )

Use "#pragma warning disable 1591" to suppress "Missing XML comment for publicly visible type or member" warnings in Visual Studio when using Unity

StagPoint / DoPlanesIntersectAtSinglePoint.cs

Created September 25, 2018 17:57

Find intersection point of three planes in C# for Unity

	private bool planesIntersectAtSinglePoint( Plane p0, Plane p1, Plane p2, out Vector3 intersectionPoint )
	{
	const float EPSILON = 1e-4f;

	var det = Vector3.Dot( Vector3.Cross( p0.normal, p1.normal ), p2.normal );
	if( det < EPSILON )
	{
	intersectionPoint = Vector3.zero;
	return false;
	}

StagPoint / ObjectPool.cs

Created April 2, 2017 14:21

Bare-bones generic object pooling. Object pools can improve application performance and memory footprint in many gamedev situations. When a client program requests a new object, the object pool first attempts to provide one that has already been created and returned to the pool. If none is available, only then is a new instance created.
