DoogeJ / SimplexNoiseTest

SimplexNoiseTest project to play around with it in MonoGame

Building and running this

• Run dotnet restore
• Run dotnet run

This should work automatically; if not you might have to install .NET 5.0 (or higher) and a maybe also a MonoGame development environment (the latter should be handled via NuGet in the dotnet restore tho).

Functionality

• You can click-and-drag; this is a little laggy since everything gets re-generated during it but should work on any average-or-better GPU (tested on a GTX 670)
• You can scroll to change scale

Known issues

• When using negative values, there are glitches extending from the zero point
• If xOffset and yxOffset are big (like (int.Max / 2) - example provided in code, but commented out), the generated noise loses a lot of definition
• The glitches seen around the zero point can also be visible in other areas of the map, especially when zoomed out with a fairly large offset
• With a scale over 5.0f repeating patterns become visible
