[Code] Rantexpos

g.moggel

hey guys. first up, i dont take credit for that plugin. its by axel lee. i found this plugin rantexpos at http://rhin.crai.archi.fr/rld/plugin_details.php?id=324

it doesnt seem to work in su 8. can one of you look into it and maybe correct it? i'm not into coding but really need this to work.

its supposed to randomize the texture position of the selected group/faces.

code is as follows.

def rantexpos
	Sketchup.active_model.start_operation("RANTEXPOS!")
	selected = Sketchup.active_model.selection   
	for ent in selected
		if( ent.is_a? Sketchup;;Face )
			tex = ent.material
			texpoint = []
			texpoint.push [rand(2048), rand(2048), rand(2048)]
			texpoint.push [rand(2048), rand(2048), rand(2048)]
			texpoints = [texpoint[0],texpoint[1]]
			ent.position_material (tex, texpoints, true)
			ent.position_material (tex, texpoints, false)
		end
		if( ent.is_a? Sketchup;;Group )
			for fac in ent.entities
				if( fac.is_a? Sketchup;;Face )
					tex = ent.material
					texpoint = []
					texpoint.push [rand(2048), rand(2048), rand(2048)]
					texpoint.push [rand(2048), rand(2048), rand(2048)]
					texpoints = [texpoint[0],texpoint[1]]
					fac.position_material (tex, texpoints, true)
					fac.position_material (tex, texpoints, false)

				end
			end
		end
	end
	Sketchup.active_model.commit_operation
end


filename="rantexpos.rb"

if !file_loaded?(filename)
	plugins_menu = UI.menu("Plugins")
	if plugins_menu
		plugins_menu.add_separator
		plugins_menu.add_item("Randomize texture positions") {rantexpos}
	end
	file_loaded(filename)
end

thanks in advance.

thanks dan for looking into it. when starting sketchup i get an error now:

"Error Loading File rantexpos.rb
undefined local variable or method `filename' for AxelLee:Module"

and still when i start the plugin from the plugins menu su crashes.

Hi,

Typo: replace: file_loaded(filename) with: file_loaded(Filename)

Parenthesized argument lists for methods. (And remove a few spaces when they were in between method names and arg lists. This causes an error in Ruby 1.8.6)
Wrapped in a module.
Added Constants at top for setting menus.

Done. Edited the code.

I did that in a secs just before bed. I have not tested it. (I assume it worked under Ruby 1.8.0, and didn't under 1.8.6 because of spaces between method names and argumentlists, etc.)

I was able to get it to work on a simple model (attached.)
SaucePan.skp

I was also able to get a BugSplat! on a very complex old ver 7.1 model. I selected the terrian mesh, and tried it on that. (splatto!)

g.moggel

hey man this is awesome. i needed to make a cutting board like ikeas whole-wood boards and they consist of individual parts glued together... anyway: NICE ONE!
although i have another thing. the textures original rotation is changed and completely oriented in the other way. is it possible to not let the rotation change or choose whether it randomizes rotation at a given angle?

thanks again, this was a big help

I don't have time myself to work on this.

Um.. if you have control.. then it would no longer be random ?

but I did notice that when I ran it on a pavement texture on a bridge model, that the roadway became misalign with the bridge. (Looked terrible.)

g.moggel

figured it out. i just need to rotate my face/object to be oriented with the axis. then i can hit rantexpos and it aligns them in the other way. thanks again for your help.
