[Plugin] Gradientator v1.21

steve r

Oh, one more thing: I messed with color.blend a little, and it seems to be pretty accurate. The SketchUp developer page only provides examples of 0.0, 0.5, and 1.0, but it seems to work quite well with Float values of any precision. However, it seems to truncate the results, not round them. So, if you're blending Red [255,0,0] and Lime [0,255,0] with these values:

color1.blend color2, 0.2156
color1.blend color2, 0.2157

In the first case, you'd expect 54.978 ( = 0.2156 * 255 ) for the red channel, which should round to 55, but instead you'll get 54 for the red channel. In the second case, you'd expect 55.0035 ( = 0.2157 * 255 ) for the red channel, which SketchUp makes 55.

So, it appears that color.blend will truncate its results, not round them. Just thought that might be useful bit of information.

That is interesting. I replicated blend in a C Extension for speed - not sure if I caught that detail. Will have to check.

Have loaded gradientator v 1.2. When using, only the first colour is applied to the face, not all three.

Any ideas?

You selected only one face? It doesn't do a gradient over a single face, but apply plain colours to a set of faces based on their distance from each other.

Thanks Thom Thom, is there anything you don't know about???

I have tried it with adjoining and separate faces and it still doesn't seem to provide a Gradient of colors. Rather, it simply adds color 1 to the first face, color 2 to the second face and so on. Do I need to stipulate the degree of gradient somewhere?

thank you for sharing it!

It seems like the issue you might be having is with the number of faces. This plugin only applies one color to one face at a time, and doesn't sub-divide them. In the picture you've provided, it looks like you've got two different applications of the plugin, but each time it's to only three faces. So, Gradientator sees that you've got three faces selected, and just applies the three colors; no gradient needed. However, with more than three faces, it will begin to gradient to greater degrees. So, trying to replicate your image with more faces:

As you can see, it's still applying those three colors, but the "in-between" faces are getting the gradient colors, or colors that are in-between those main colors. So, the amount of gradientating you'll get is dependent on the number of faces you select at one time. Does that help?

Steve,

many thanks for clarifying that for me. I had missed the point that I needed more than three faces. From the initial illustrations it had looked like only 1 face was having colours gradiented (no such word??) across it.

I've got it now. Just needed to be belted on the head a couple of times!

It shows an error on sketchup 2014

how to

Using Notepad or similar text editor, simply remove the '@' in |@grad_dialog,action_name| in line 79 to this

@grad_dialog.add_action_callback("get_data") do |grad_dialog,action_name|

That works, Cheers Sd.

Thx a bunch Mitch.
Just plain fun to mess with.
Works too

In SketchUp 2015 I get the following error after the install:

Error: #<SyntaxError: C:/Users/nessuno/AppData/Roaming/SketchUp/SketchUp 2015/SketchUp/Plugins/gradientator.rb:79: formal argument cannot be an instance variable
...ck("get_data") do |@grad_dialog, action_name|

C:/Users/nessuno/AppData/Roaming/SketchUp/SketchUp 2015/SketchUp/Plugins/rubytoolbar/rubytoolbar.rb:190:in block in <module:RubyToolbar>' SketchUp:1:in call'

I solved changing row 79 to the end of the do block in this way

@grad_dialog.add_action_callback("get_data") do |grad_dialog, action_name|
			if action_name == "begin_gradientating"
				@grad_dialog = grad_dialog
				@coloronename = @grad_dialog.get_element_value("color_one_name")
				@colortwoname = @grad_dialog.get_element_value("color_two_name")
				@colorthreename = @grad_dialog.get_element_value("color_three_name")
				@grad_dialog.close
				gradientate(@coloronename,@colortwoname,@colorthreename,@faces,@model)
			end
			if action_name == "close_this_window"
				@grad_dialog.close
			end
		end

So do I. Would love to try this plugin....

Andrew, did you try the solution offered by sdmitch? I just tried it and that makes it work in SU2015.

The post just before yours offers a solution http://sketchucation.com/forums/viewtopic.php?p=575140#p575140, and @sdmitch gave an even simpler version a few posts earlier http://sketchucation.com/forums/viewtopic.php?p=541222#p541222
Just edit the RB using a plain-text editor like Notepad++, then find the do |@grad_dialog, text around line #79, and remove the @ so it's do |grad_dialog,.
Save the RB and restart SketchUp...
Since the @grad_dialog is defined earlier it is not necessary to redefine it in the do block, so using ANY name which doesn't start with a @ will work !

utiler

Thanks Dave / TIG. Trust me to jump into a new plugin without reading through recent posts.... Cheers, I'll give it a crack tonight!

utiler

Worked a treat, guys. Thanks!!!

I'll post in a few days what I needed it for. Glad to share....

Works fine!
