[Plugin] GreyscaleMode

[Jim]

Dave R somehow talked me into writing this plugin, so here's a video and a download.

The plugin switches the in-model material colors to grey scale, and back again. The grey color is calculated as an average of the RGB values.

The model can be saved in Grey mode, and the original colors will be preserved upon opening the model again. Color changes made in Grey mode will be kept.

While in Grey mode, right-clicking a face will revert the face's material back to its original color.



GreyScale is available from here

Cheers jim, works like a charm.

[solo]

Cool, not sure I will need it but I collect ruby's and this one works great.

[Daniel S]

Great!!!
Thank you Jim!!!

[solo]

Even beter, it renders in grey scale too.

[Frederik]

Cool..!!
Thanks..!!

[Dave R]

Here's my public thank you to Jim, too.

THANKYOU!

Once I get permission to release them, I'll show some images I used it for.

[JuanV.Soler]

First of all I'll echo Dave_R's comments. Jim, you are a generous fella...

For those of you who didn't see how this evolved, see viewtopic.php?f=40&t=12226&p=88778#p88778

Sometime, a schematic presentations seem to be best a little less 'in your face' in grey scale...

I tried it out on a little modular house I designed...

The only problem with it is that it doesn't act like 'face styles' in that changing from one scene to another it doesn't save with styles....

Not complaining though!!! Would love to see it included in SU7.0 face styles...

Thanks Jim.

[plot-paris]

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.

[Pixero]

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:

Code: Select all

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

[Dave R]

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

Thanks Jim!

[drewpoeppel]

Thanks a ton this is VERY helpful.

[gaucho]

Good stuff Jim, thanks!

[sepo]

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

[utiler]

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?

TY " You're Good !!"

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.

[zed252000]

this is just Awesomely Good.
Thanks!

[Jim]

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.

Dave
