So I'm trying to display 1000 prime numbers, and getting the camera to rotate around the set of blocks. But the generated image never stays. It draws once and never updates. I need fresh eyes to look at this code. Why does it do this? To test that it's just that codeblock that has the problem, a sphere was added and it rotates as it should.

The one way that seems viable is the use of bl.ocks.org and posting up sketches as gists on github, and directing users to the bl.ocks.org site, but i want to loadimage, and not too sure if there's a same site origin policy on that function.

That seems kind of hackey to me. So is there a way to get the sketches out there?

So is does the program need to sleep for a certain amount of time to determine if the load is successful?

 

how can you tell if a processing sketch in java is translatable into processing js?
