Over the last few months I have been working with noise generation algorithms. My latest of which is a resampled noise heightmap which builds on from my learnings from Experimenting with Simplex Noise in Java. I have added a colour spectrum to help visualise the generated data. This 1024² sample takes less than 2 seconds to generate – including all object initialisations. A substantial performance increase over my Experimenting with Perlin Noise in Java work.
Hey it also looks pretty cool I think.
