[sigh] I wrote that I had Canvas3D 0.4.3 installed in FF 3.5.2 Read your own blog…

The error is the same:

11:59:37 Error: Fragment shader uses varying gl_FrontFacing but vertex shader does not write to it.

If you are viewing off the website (ie just following andor’s link: http://www.c3dl.org/wp-content/blog_demos/orbiter1.1/orbiter/orbiter.html) all you need is the canvas 3D addon installed.

If you downloaded the code and want to see it locally you will need to get the library.

BTW: I’m running the Intel GMA4500 video chip. I think there was another thread addressing this problem with the GMA4500 video chip.

…downloaded c3dl 1.1 — still get the same error –

19:22:1 Error: Fragment shader uses varying gl_FrontFacing but vertex shader does not write to it.

So the question remains — do I need c3dl 1.1 resident on MY computer to run Orbiter 1.1?

I understand that c3dl 1.1 is not WebGL compliant. I am trying to run Orbiter 1.1 using FF 3.5.2 and Canvas 3d 0.4.3.

If I understand your comment correctly — I need to download and install c2dl 1.1 somewhere on my computer to run Orbiter 1.1. Right?

1.1 of c3dl is available via download section. It is NOT webGL compliant. It still works with Canvas 3D addon for FF 3.5.x. This is the version that the orbiter demo is working with. We are currently working on porting over to WebGL though so stay tuned .

…also, Orbiter 1.1 does not work on my system. Is it expected that I have your 1.1 library on my system to run your demo? Your Orbiter 1.1 page uses relative file path to your library so I assume that it is somewhere on your system. But it doesn’t run.

var SCRIPT_PATH = ‘../canvas3dapi/’

I have Canvas3d 0.4.3 in FF 3.5.2

I get this error:
19:22:1 Error: Fragment shader uses varying gl_FrontFacing but vertex shader does not write to it.

Some questions:

How do I find out which version of your library I have? I have a version and it works with some bugs but it works. But your library changes so fast I guess I should always stay current with the latest release.

I noticed that you have a Minefield release (FF 3.7) Does that version of your library work with WebGL yet?

On OS X and Windows is seems to be the same for me. I’ll have to look at your mac.

This demo behaves differently on mac vs windows. On windows, there appears to be a sun, and the shadow of how the earth is facing shows. On the mac, the light is just one big light (always daytime everywhere).
