Color gradient?
-
Hello,
I need to merge the color of two areas. I was thinking about using a color gradient. Is this possible are do there exist easier possibilities to change the color gradually?
I tried textures, but this did not work out (my final two areas are quite complex and I need the gradient starting from the end of one area into the other).
Thanks a lot. -
Its hard to say without seeing the specific situation, but it sounds like you might have some luck with projecting a colour gradient texture on to the mesh.

I tried to use a gradient texture. But I have curved areas and I only could find out how to stitch the texture in a specific direction (and not along the curves).
Any trick? -
Is it a flat or fairly flat piece? such as the land or something? You could try turning everything off except for the faces to color. Then get a straight down view. Then export that as a screen capture and open it in photoshop. Then take that and use that as a template to make the color gradient how you want it. Then take your new gradient image in to sketchUp and scale it and line it up directly over the model and then do as Remus suggests py projecting it down on to your geometry. That is about the only way I can think to make it work without getting too fancy and using another program or plugin to do the UV mapping.

ticoloco,
You can use 'projected' texture, as demonstrated in this terrain model:

(See #12, 'Using images as signs')Note: Don't overlook the note at the top of the page, regarding the 'EnSharpen' codec.
That should get you started... (if I'm reading you right.)

If your geoemtry isnt straight, you can take your colour gradient texture in to something like photoshop and use the warp tool to stretch the texture to the same approximate shape as the geometry. You can then import it back in to SU and apply it as a projected texture as you would normally.

Thank you TaffGoch,
unfortunately, this will work only for height differences. My model is much more simple, they are two 2D-coils with some straigt connections where I need the gradient.
I don't have Photoshop, so are there easy tricks (Ruby or directly in SU with the paint bucket tool) to succeed?
Thank you -
I'm afraid the answe is no. Unless someone has something amazing up their sleeve....? But I don't think so. SU just isn't great with gradients.

@remus:
I am trying your advice but have some problems with it:
1.) I use the following procedure to project the image (from the sketchup docs):
A. Create a model, such as a cone, topography, or building front. This model will receive the projected image.
B. Insert an image using File > Import. The cursor changes to the Select Tool with the image.
C. Place the image in front of the model that will receive the projection.
D. Size the image so it is large enough to cover the entire model.
E. Context-click on the image and select Explode to turn the image into a projected texture.
When I do so, somehow the overlayed image gets semi-transparent. I can still see the original color of the object. When I delete it, then I get a semi-transparent object - the colored face seems to be behind the (flat 2D) object, no matter from which side I look at.
What am I doing wrong?2.) The resolution of the exported image is quite low (I magnified the object as max as possible) so that I can clearly see the borders when overlaying. So, saving various images? Or are there other ways to get more resolution?
Thanks

Could you upload a copy of what your talking about there? I'm not quite following what happened, but it might make more sense to see it. Thanks,
Chris
