[Plugin] Bitmap To Mesh

Dave R · 3 Oct 2010, 12:31

Well, it's all voodoo to me so I am glad we have folks like you.

Version 0.2.0b

Made into a tool so the user can easily position the mesh
Moved menu to Draw > Mesh From Bitmap
Keeps aspect ratio of image or Image element
Right click and Image element to generate a mesh. (Does not need to be BMP image - but Draw > Mesh From Bitmap still require BMP imput)
Colour BMP images will convert the RGB value to optical greyscale.
VCB support

Test using sample maps from: http://www.mtgrafix.com/programs/terrain.html

Also tried this: http://www.twisteddirt.com/TutorialStuff/dem_02.php Nice terrain shape - but the diffuse texture wasn't so good.

308px × 1 047px - that would make the mesh ~500-600K faces?

And the issue with that bitmap is that despite it being a greyscale, it's still not a height map - which is why the mesh doesn't come out looking as what the image illustrate.

Yes, true. I just wanted to test it - the file is 105 MB

thomthom · 3 Oct 2010, 16:18

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?

thomthom · 3 Oct 2010, 21:41

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.) 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.

After letting a 384x384 (meters) heightmap simmer:

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.

David,
Use the scale tool to compress it vertically.

david_h · 6 Oct 2010, 19:14

oh well. . . there's one for the duh thread.

Thx

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