Modernizing a codebase for C# 9

Modernizing a codebase for C# 9

There are lots of cases that you can improve. The examples use nullable reference types, but only the WhenNotNull example requires it.

Use the property pattern to replace IsNullorEmpty

Consider adopting the new property pattern, wherever you use IsNullOrEmpty.

string? hello = "hello world";

optimizing & de-duplicating geometry in GLTF files

optimize GLTF file

This optimizes a GLTF file that was exported by blender (or similar) by de-duplicating buffer views (i.e. chunks of bytes) that are equal and removing redundant accessors.

For example, 100 cubes of different scales/materials/rotations/etc should all end up using a single BufferGeometry in ThreeJS, which isn't the case with current GLTF exporters in Blender and parsers for ThreeJS.

In scenes with a lot of instancing, it can dramatically reduce total file size as well as render performance. In one test scene:

Before: 4.8MB file size, 832 THREE.Geometry instances across 832 THREE.Mesh objects
After: 661KB file size, 13 THREE.Geometry instances across 832 THREE.Mesh objects

Convert WGS-84 geodetic locations (GPS readings) to Cartesian coordinates in a local tangent plane (Geodetic to ECEF to ENU)
using System;

using static System.Math;
// Some helpers for converting GPS readings from the WGS84 geodetic system to a local North-East-Up cartesian axis.
// The implementation here is according to the paper:
// "Conversion of Geodetic coordinates to the Local Tangent Plane" Version 2.01.
// "The basic reference for this paper is J.Farrell & M.Barth 'The Global Positioning System & Inertial Navigation'"
// Also helpful is Wikipedia: http://en.wikipedia.org/wiki/Geodetic_datum
