Planetary perlin noise? My oceans are too patchy.

I don't have a definitive answer but here's what I can add: If you're using Perlin Noise, try doing multiple passes. After the first one, just randomize again, but on a smaller scale, just like Fractals, where it's recursive and repeats itself, while gradually beco$$anonymous$$g smaller and smaller. This will give a more definitive and less gloomy look, like real terrain.

Also if you want continents and oceans you're gonna need to define areas where the vertices' radius from the center is less random and more offset than others, either towards the center (ocean) or away from it (terrain).

In the end it all comes down to how random you want it to be, and how realistic, because creating an algorithm that could create earth-like planets that are completely random each time, would be very difficult.

Yeah, I pretty much need less random areas, and then strict borders between them. That's what I'm looking for.

Take a slower walk through the perlin noise to reduce the resolution of the bumps. You could also use a grayscale bitmap ins$$anonymous$$d of/in addition to the perlin noise. That way you could 'paint in' in the large continents.

But I would still like a procedural planet, what do you mean slower walk?

If you take a look at the example script for PerlinNoise() you will see:

 var xCoord = xOrg + x / noiseTex.width * scale;
 var yCoord = yOrg + y / noiseTex.height * scale;

The 'scale' changes how far to move for the next sample. If you move a smaller amount, you will move less on the 2D plane. It's like zoo$$anonymous$$g in on a part of the plane so you 'see' less bumps.
