WebGL support

Open pierre0042 opened this issue 10 years ago • 9 comments

The screenshot of a page with WebGL elements doesn't seem to work with any of the engines.

example : http://webglsamples.org/blob/blob.html

It would be great if it could be supported :)

I've already seen this issue: https://github.com/vbauer/manet/issues/5

Could you please try to switch engine to slimerjs and configure delay parameter (for example: 1000)? I've just tried to catch screenshot using http://localhost:8891/?url=http%3A%2F%2Fwebglsamples.org%2Fblob%2Fblob.html&delay=1000&force=true and it works fine.

Sorry for not seeing the closed issue.

The fact is that I used those parameters (I even set delay to 2000). All I am getting is this : https://imgur.com/sgeyY7J

What could be wrong? I am using Ubuntu Linux 15.04

Hmm.. I've just checked it on OS X 10.11 and Windows 10 and got the following result:

test

Command: http://localhost:8891/?url=http%3A%2F%2Fwebglsamples.org%2Fblob%2Fblob.html&delay=2000&force=true&engine=slimerjs

Is it possible test it on another OS? Could you please also try to set some big value for delay parameter (something like 30000)?

setting delay to 30000 doesn't change the result

pierre0042 avatar Oct 15 '15 21:10 pierre0042

It works fine on Windows 7 SP1. (I just had to specify --command as the default binary name for slimerjs seems now to be just "slimerjs" and not "slimerjs.bat")

Ok I got it to run in my Linux with overriding the command too (manet --command slimerjs).

Using xvfb doesn't work when you are using a real graphical environment.

I will try to test it now in a Linux server without X.

I tried with the docker image https://github.com/pdelsante/manet-dockerfile and it doesn't seem to work

pierre0042 avatar Oct 16 '15 14:10 pierre0042

I made a fork of the docker image that fixes WebGL rendering. https://github.com/openmaphub/manet-dockerfile

The two main things I did were:

  • Installed Firefox (which probably installs a missing dependency of some sort)
  • Added this xvfb script https://github.com/samgiles/docker-xvfb

I'm really sorry for a long response - just a lot of work...

@kriscarle Thank you for https://github.com/openmaphub/manet-dockerfile ! I've just updated README and added information about this project.

@pierre0042 Have you tried https://github.com/openmaphub/manet-dockerfile ?
