[Plugin] Normal Map Maker

Chris that's excellent
Nice pink background in SU too
-
Dang. Though this is good, I for a moment thought you had found a way of SETTING the normal in SU.
Oh well, maybe in SU 12...

I normally just have a white background, but with edges off and having just a pure white geometry, I could not see my geometry, so I needed a background color. Pink seemed to fit the groovy "normal" colors well -
Excellent, Chris! Thanks! -
Also, if people don't like copy and pasting code into the ruby console, I could further develop it to be a regular install plugin that goes into the menu system. Maybe if I get some free time. I prefer menu items personally.
-
You described an easy and excellent way to make b&W displacement/bump map in another topic (using a gradient black-to-white image projected sideways...).
If you ever develop this plugin into a menu item one, could you also include that option? (although true that it can easily be done simply manually, too).
-
+1 for menu
+1 for Gaieus suggestion
+1 for +1
-
Thanks a lot Chris for this one. Hope you'll find some time to make a menu for this one...and +1 for the Gaieus suggestion.
Cheers.
-
Great, thanks Didier! You added pretty much everything else I was hoping to get to later, just didn't have time at the moment. I can redo my video tutorial and stuff later when I get a chance. Hopefully tonight.

Chris and Didier, Good work. This is a very neat function added to Sketchup's "bag of tricks".
-
Neat!
-
Thanks Didier, too!

Hi,
Here is my contribution to this nice idea.
I hate commands in the console, etc, so I've made it a plugin.It sets temporarily the display style without edges and edges profiles, resets it after the tool has ended.
It restore all the original materials of the faces and also purge unused materials.
You'll find the command under the File menu -> Export normal map@Chris: I hope you don't mind me tweaking your script...
EDIT: modified on Dec. 8th 2010(menu option not working)
-
Hi,
Just edited the script and re-uploaded it, because the menu option was not working.
Sorry for the inconvenience, -
It is a nice step forward!
I was thinking about using TIG's Java solution and produce a PNG with proper aspect ratio and without modifying the original materials. I don't know how to calculate smooth normals over a whole face when an edge is smoothed in SU, but I bet it can be done.

I've been thinking about using a jar to mimic 'make_unique' for skewed textured materials etc as exporting these with correct UV mapping to tri-faces is not possible [or at least I don't know how to do it] - the way the built-in OBJ exporter copes is to make special versions of the texture image files that have non-exportable distorted UV-maps [from skewing etc] and then use those as a non-distorted image in the OBJ code... It's relatively easy to distort the width/height of an image in java BUT skewing is more tricky - but possible... e.g. http://www.jhlabs.com/ip/distorting.html and http://www.jhlabs.com/ip/filters/index.html or http://java.sun.com/products/java-media/jai/forDevelopers/jai1_0_1guide-unc/Geom-image-manip.doc.html

Sketchup::TextureWriter allows you to write out distorted images. If you load a face with distorted texture to the TW and write it out it'll save a modified version of it. Oddly enough, it doesn't seem to work the same way for skewed, scaled etc - then the texture is the original texture.
-
And it's the skewed one we want!
-
ah...
But a skewed texture only needs three co-ordinates - why are these troublesome for triangles?
