Do the manta ray...

My web hosting company as just moved my server to a new hosting company.
They didn't move the website though, so the weblog has been republished :-)

planetGenesis has seen some loving recently. There are three new combiners
due to hit CVS any day now, to go with a big optimisation for Worley based noises
(10% faster) and a very small Perlin optimisation (1% faster, you might notice it :-)

The new functions allow you to replace one of the noise co-ordinates with
noise, so instead of noise based on x,y,z co-ordinates, it could be based on
x, perlin(x,y,z), z. Not really useful for planets, but landscapes where the
y co-ordinate is always the same values you can start to mix things up
a bit. It you feed the same Perlin noise in both inputs you can get some
lovely height fields, here a quick example.



The idea came from my top secret project postGenesis, oops.
