[Plugin] GreyscaleMode

Thanks Jim.

thanks a lot Jim! this ruby is a nice enhancement for producing stylised output with SketchUp
utiler, you did a perfect example what the script can be used for.

@Remus (completely off topic): I really like the reincarnation of your avatar-image. its a bit like Gandalf the Grey / Gandalf the White - I had to look twice, but I did recognice you in your new guise.

Jim: I see you use the average of r, g and b to get the greyscale color.
A often used and more visually correct way is to use this formula:

Greyscale = (r * 0.3) + (g * 0.59) + (b * 0.11);

Great!!!

Coen, I couldn't find a way to do this with existing style settings. I'd be happy to learn it though.

Good stuff Jim, thanks!

Nice ...It renders black and white in Podium but keeps the colour of the sky ( i presume ground as well)
It would be nice to be able to choose say one colour which could stay as colour ...
Thanks Jim ....

Dave R

Sepo, after making the model all grey, right click on a face containing the color you wish to show. Choose Revert color from the menu.

sepo

Aha...cheers Dave did not pick that up...Cool. Any chance to actually have more than 10 shades of grey. That would make renders nicer.

Dave R

As I understand it, Jim's method of creating the gray values is to average the RGB values and apply that number to all of the RGB settings. I don't think we're limited to 10 steps as was discussed in the other thread.

sepo

Actually I think you are correct ... discard the last bit

I like it and thanks, but can't this be done using a Style?

I agree, Coen. A face style. That way we could save it to styles and scenes.....

It wound allow us to 'revert color' in a style / scene though I wouldn't think..... Jim?

Thanks and you're welcome, everyone.

Having it work as a Face Style would be nice. Face Styles can be selected in Ruby by setting an option called the RenderMode. There is just not a way to create a new Face Style that I can see.

Like Dave said, I don't think a Style is an option either. There is no control over individual colors in a Style.

The idea of saving material changes between Scenes is a completely separate plugin...

utiler

You're right Jim, that's the only thing that restricts it from being a 'face style' option. It would be nice to be able to "update scene" individually rather than a ruby that effects the model period....but that takes away from the "reverse color" option....

I guess if this was a face style and we wanted to 'spot color' an element, we could set up diferent components and scenes then import into Layout and overlay scenes.....a round about way of doing things though and getting into another topic, 'more than one style in a drawing / file'.

Five Star, Jim.

this is just Awesomely Good.
Thanks!

Hi Guys,

A word of caution; utiler has reported he was not able to get the right-click "revert" color option using this plugin. I'm not sure why, but it may mean that the script could "forget" your original material colors. I'm looking into it.

EDIT: There is no danger of loosing the original colors. The error was caused because the default color returns nil when asked for its material.

Dave R

Jim,

Thanks for the warning. I haven't seen that problem but I'll keep my eyes open and let you know.
