Chain combineKernels?

[pan-long]

When I try to pass a combinedKernel into combineKernels() to chain them, I got this:

Uncaught TypeError: arguments[i].setCanvas is not a function
at GPU.combineKernels

Can we getore context, like example code?

I'm using GPU.js to run bellman Ford algorithm, code here: https://github.com/pan-long/SSSP-on-GPU/blob/master/bellman_ford_gpu.js I have to have a loop to keep running bellmanFordKernel, it's now slower than Dijkstra running on GPU. I'm wondering is it because of performance penalty brought up by keep transferring data between CPU and GPU. Then I found out combineKernels, but it doesnt support chaining.

I think you are dead right. We need to add this as a feature, so we can chain values through. Give me some time this week and I'll add support. We'll get this thing faster!

Can we have access to that code again? Or something simple that outlines the chaining being done? Clarity helps us help you! 😉

Hi, I have made it public. Thanks for your help!

Been thinking about this over the weekend, I will have a solution soon, fyi.

This needs clearer direction. Can you give a non-working jsfiddle?

I have run into this bug... Great library btw!
