rendering_options, "back edges"

[daiku]

How do you dump out the list of rendering options? I'm looking for the parameter for the new "back edges" edge style in SU8. CB.

Thanks. I can't see any differences between when "back edges" is turned on or off. CB.

You are correct. I filed a beta bug report, and Simone logged it as internal bug 2916316.

Additional comments, and ideas I posted:

OK.. I looked at this a bit further, and my conculsion is that...

RenderingOptions[’EdgeDisplayMode’] needs to be updated.

The setting is tied to Edges

Currently the value of the RenderingOptions[’EdgeDisplayMode’] key is 0 when both are turned off.
Toggling Edges ON adds 1 to the value. (BUT.. if BackEdges is ON, and you turn Edges OFF, the value remains at 1.)

We need toggling BackEdges ON to add 2 to the value, so that:

RenderingOptions[’EdgeDisplayMode’] :
0 = both OFF
1 = Edges ON && BackEdges OFF
2 = Edges OFF && BackEdges ON
This may not be used (rendered,) meaning that mode 3 would be enforced, but we should still be able to test for mode setting 2 (the state of checkboxes in the Styles dialog, and the menu item check states.)
3 = both ON

thanks, but
in ruby console

Code: Select all

Sketchup.active_model.rendering_options["EdgeDisplayMode"] =

works only 1 and 2

Sketchup pro 8.0.3117

It should only have 0 and 1 values at this time.

You did not read what I said correctly. I am proposing that values 2 and 3 be added to the API so that we can know the BackEdges setting.

Sorry, i mind 0 and 1..
And how can I add it to API? =)

ps. my English is not good

[Dan Rathbun]

And how can I add it to API?

You CANNOT.

Google must do it on the C++ side of the application code.

That is why I filed the Bug Report, and a number was assigned to it, by the Sketchup Development Team.

Any updated info for this topic?

Any updated info for this topic?

YES. (5 years after this thread ...)

In the SketchUp 2015 release, a new key was added to the RenderingOptions hash:

The key is: "DrawBackEdges"
