? Can you describe your process?

Playing with it is cool, but there's a huge "BUT" from two bitmaps I used in single SU file (400x400 & 200x200) it made my file 60MB big! It's much to much. My PC handles aprox.100MB files, but they're almost uneditable and hard to use. So what do we need this plugin for? Maybe some small not complicated architectural details? Simple scenes?

400 * 400 = 160000 (that's just tiles - but these have to be triangulated, so the actual number of faces generated will be 320000)

If you use a render engine that support proxies you can generate a high res mesh and generate a proxy object of it and use a low res mesh in your model.

It should work for SU2014. Download latest from SCF PluginStore or the Extension Warehouse.

Or have you already done that and found errors?

I cant figure this out, been trying for ages and cant make the plugin seeable from the plugin menu even after installing the extension.

running win7 with trimble 8.0.151158

I can get other plugins to work perfect but the TT_Lib2 not showing or the bitmap to mesh either.

any help please

This plugins doesn't add menus to the Plugins - it adds it to the Draw and Context Menu. See the description for details.

Is it possible to take a closed loop of edges, and fill them with a bitmap?
Kinda like the Soap Skin & Bubble plugin douse.

Like a height map, or making faces out of each pixel?

I was stuck on the exact same problem and was able to make it work by changing my steps to:

File > Import...
Navigate to your image file, select it and click Import.
Place and size the image in SU.
Right-Click on the placed image and select Mesh from Heightmap.
Pick depth by clicking somewhere on the blue axis above the image.
The plugin will take some time to index the points and generate the mesh.
May have something to do with file format. I don't know.

Thanks thomtom for a great plugin. I am trying to use it to generate terrain from downloaded TIF heightmaps. Still trying to figure out what size image is doable.

Yes like a height map (if i understand what a height map is correctly ).
If i have a spesific face that i have to work with, and it represents a water surface:

I woud like to add small waves to that face like Mistro11 did in this post
Is there some way to bound the bmp to that face?

Why not just make the mesh from a rectangular bitmap and trim it to that shape after?

tt_su

The mesh would be incredible dense. Are you rendering the image eventually? I'd then put use the render engine and apply the bitmap as a bump map or displacement map instead.

I agree with both of you. Trimming it or rendering it would be a solution. But still i am curious if it is possible to bind the bmp to a face.

This plug in is amazing, thank you so much.

But it took me a long time to find, I suggest in your extension warehouse keywords you add "Displacement Map" or Displacement baking and similar stuff to help others find it.

nice one, could be useful for landscape modeling in my case.
ive probems to draw the depth plane.

-i loaded a bitmap noise image into su
-i defined the origin and width, while with depth im unable to confirm, the click is blocked.
Also using a numerical imput and confirming that op doesnt work.

Any errors in the Ruby Console?

Make sure the bitmap is 24bit and that it doesn't include color space information.

To those people having an issue with not being able to click when prompted to Pick depth, make sure that the image you are using does not have any color space information. I believe that someone already mentioned this awhile back in the thread.

The link below shows an image of the GIMP export settings when exporting a BMP image.
Notice that I have Do not write color space information checked.
I have no idea how to check if a BMP image has color space or not. Best bet is to open the image and save/export it without color space information.

Hi Thom,I have been trying to install this jewel for three days,and not able to do.
Had read several times almost every thing at the forums without success.
Could you give me a hand please.
My OS X 10.6.8 and Skp.8.0.15157 free.
This is what appear in the ruby console:

Can you share the image you try to load?
