Returning back an array per pixel

[ZeepXanflorp]

This is more of a question than an issue:

I'm trying to write a bhuddabrot with webmonkeys, where each calculation based on a pixel returns a cloud of points which are then laid upon each other to create the final image. in OpenCL this is achieved using a shared array. After some digging, it looks like WebGL is written so that is returns one vector per calculation, and cannot return an array or access a shared grid in memory. Is this correct, or have I mis-understood the examples?

Sorry, I do not understand the question.

WebGL is written so that is returns one vector per calculation

And similar sentences make no sense to me...

I'm sorry my question did not make much sense - I'm not too good at the terminology. I see a lot of the examples have a kernel calculation that return a single value, usually placing that single value into an array (often called nums). However, per kernel calculation, I want to return an array of numbers, not just one. I.e. set all the values of nums each kernel calculation. What is a good example of this?
