Slope analysis of 2d Autocad contour drawing
-
I have made my terrain but couldn't do my thing
I want slope analysis like this 0-5% ------ very light brown
5-10% -----little dark brown
10-15% ---more dark brown
and so on till 25% and above ----- darkest brown
Chris fullmer plugin does this by itself not lettingme put values.

Perhaps you could use Photoshop or Gimp to replace colors?
Oh wait. It's not letting you dictate certain slopes. just it's own determination huh? I think this is going to be something that doesn't exist.

You can make a new post in the Plugins forum here. http://sketchucation.com/forums/viewforum.php?f=323
Title it [REQ] Slope Analysis and then describe what you are wanting it to do very specifically. There are many developers and if this interests them they'll make it. Or they might tell you how to make it or how it can be accomplished.

if you read through the color by slope thread, you'll see that TIG has written the code to get the desired function.. it hasn't been added to the published version though..
i'm going to assume neither chris nor tig are going to combine it or else it would of been done already.. most of the requests in the thread were to have the functionality which tig addressed.
basically, someone with some ruby knowledge will have to explain (in simple terms) how to add tig's code to color by slope..
(i just tried and failed miserably..

Yes, it is determining by itself. Auto mode, i just enter rgb values and it does the thing by itself.

I've PM's you an adjusted version of Chris's RB that should do what you want...
-
Oh do share Tig...
-
Oh it's Chris' plugin adjusted... I understand.

Thanks a lot!
There's one little problem.
I made the terrain using topo plugin of fredo. The faces that i colour using modified plugin are coming in ugly triangular fashion. What can i do to make the colour smoother?
-
You can't.
The facets are individually colored depending on their slope %.
If you make a more subdivided mesh [with finer settings or using say Artisan to post-process it ?] the facets will get smaller... but they'll always be small triangles of a single color, no matter how small they get.
You don't want to go too fine as the extra geometry will slow down SketchUp significantly...There is way of using a 'projected' graduated textured material initially on a large vertical face to show faces of differing heights smoothly transitioning - from dark to light say - on a terrain mesh.

But if you think about it a little... you can't do the same with 'sloped' facets because those can occur anywhere in 'elevation'...
How could you ever get the right effect between two adjacent slopes which could be at any other slope compared to the first one you considered ? Also every triangle would usually have three neighbors each needing a different transitional graded color/texture and then those in turn etc... -
Okay, so what is the most visually cleanest way to do this?
Subdividing with Artisan only or any other free alternative?And I'd like to thank everyone who guided me to this stage.
I've visited this forum after a really long time and getting a specially customized plugin messages to me, simply blew my mind away.
Thank you TIG sir and everyone -
This place is mind blowing... It's a fantastic community of dedicated folks who love to help. It's the best forum I've ever known. Tig is one of our Rock Stars... His personal contributions to our community are staggering.

I am looking for the exact same thing. Would you mind PM'ing me a modified .rb as well? Thanks so much for constantly helping out the community.

When reading this a thought came to my mind - how does SketchUp shadows work? Isn't it a graphic representation of the angle between sun and the face. And it is smooth. The same could be used in this case. Sorry if I am talking nonsense. I am not the TIG
