Yea - the last texture I tested was 512x512 - heavy mesh. And I'd forgotten that Autosave was on - every 5 mins. x_X

Why don't I get the Curve Simplification to work?

hm... possibly you have a version where it failed on closed loops. I might not have uploaded a corrected version...

So I notice these wonderful meshes created. How is one controlling the height of the extrusion?

The pieces on the roof (above the pediment) are made with your plugin :)

So I read the posts and then thought nothing of trying a 2048x2048 heightmap produced by L3DT (terrain generating program.) :shock: Maybe I should try a bit smaller at first. Then I won't just freeze sketchup and make my patience run out... :?

I will try with a smaller (much smaller) one first and post the results.

Color, the darker the black and brighter the white will produce the greatest crests and troughs.

I get that easy enough. its all based on contrast. . .so One must go into PhoShop and manipulate and lessen those contrasts before putting it into the plugin? Because when I down loaded the scrolly motif lintel thing, I got all kinds of mess. I just couldn't get my model to look like others were doing. . .

I'll keep playing with it.

With version 0.2.0 you specify the height your self - either by using the cursor or entering a length in the VCB.

thomthom, this is very cool. I can hardly believe you got this to work. I use this in Eon-Software's Vue and love it, now that it can be done on SU is incredible. VERY NICELY DONE! :sketchstatic:

Thank you for this great plugin. :D
I did a quick test with it on a picture of a friend of mine with minimal pre-processing (just making the background black) and placed it on a norwegian coin.
I think with some more effort, one can achieve much better results.



It do however generate a mesh that is very big. I suppose merging the squares (?) which lie next to each other in the same height, would make it lighter?

Yea, it produces a very dense mesh - You can use my Cleanup script to remove edges between coplanar faces.

Nice coin by the way. :D

This plugin is great!

I use Sketchup with Phlatscript plugin to generate code G (2.5 D) to use on my CNC Router, lack a 3D plugin for editing G code on Sketchup.

For 3D and 4D, still use the Artcam,; Now with this plugin can create 3D models from photos, right in Sketchup.

Thank you.

The plugin works with bump mapping. I have no idea about what I am saying, but could it work with normal and displacement maps?

I have no idea about programming, except an unfinished Interactive Fiction game 5 years ago in the "popular" inform 6 language :shock: :lol: :lol:

Displacement maps are the same as bump maps - grayscale heightmaps. As for normal maps, I don't really know how they work...

I have found a lot about normal maps here:

but it's written in chinese, or C++ ... :lol: I don't know if it may interest you, I was spending my time a bit (as I don't understand a single word :D )

That would be simply resizing the bitmap down - which is much more efficient to do in your favourite image editor than via a Ruby plugin.

What image are you feeding it?
How large?
If you keep the Ruby Console open, do you get error messages?
