[Plugin] Bitmap To Mesh

Tandem

Ok i got the Lib thing sorted but im still running into that issue where "mesh from heightmap" wont allow me to select depth, still confused, anyone else had this issue and solved it?

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.

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

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:

Failed to read /Users/AMADO/Desktop/PRUEBA 1.bmp
BMP Magic Marker not found.

THANK YOU

thomthom

Can you share the image you try to load?

Efrado

Thank you for your fast answering. By the way,what do I have to do to select image clicking the right button on my mouse.
Continuing with the attempt to install the plugin (the only one after easy install) I got this message in the skp. screen

this is the bmp image:

Thankyou

thomthom

That first image doesn't appear to load. (You can upload directly to the forum btw.)

Efrado

Hi Thom ,sorry I am not so good with the driven of posting images. I hope this is the one

I changed the setup of my mouse and could get the width rectangle but could not get the height

thomthom

Hmm... That message about not being supported - it would indicate you have an OSX version older than 10.7. Though that seem rather old - as it incorrectly matching your system? What is your OSX version?

Efrado

HI Thom, this is what I have:

So what do I have to do in order to get your plugin works under this circumstances?

TIG

You have an old [now unsupported] OSX 10.6
As TT said, you need to have at least 10.7...

Can't you update your OS ?
There is the 'Software Update...' button on the 'About This Mac...' dialog...

If for some reason you can't upgrade your OS, then several Extensions [including this one] will not work...
That is the limitation, unless you change things...

Also SketchUp no longer supports v8 [and v2013 will cease shortly] - also several Extensions will no longer work in older SketchUp versions [this is often irrespective of the computer's OS, since they might rely on new API features, which are unavailable in those older SketchUp versions] - so why no 'bite-the-bullet' and upgrade both your OS and SketchUp version ?

thomthom

I'm afraid the 10.7 requirement is because I no longer have machines to build for older systems. For every release of OSX it gets harder to support these as well as older versions. I might have to drop 10.7 soon as well given the frequency of OSX releases.

thomthom

Only thing I can think of to run 10.6 would be to try one of the older versions of TT_Lib: https://bitbucket.org/thomthom/tt-library-2/downloads

Though you will then have less features and bug-fixes.

I'm also not sure which version might be compatible.
