[Plugin] Terrain Reshaper

[chango70]

Man u are the reason Sketchup is half as cool as it is for me! Keep it up!

[boerenkool]

Mille grazie !

[redot]

Thanks Didier. Great plugin

hi Didier,

I just wanted to clean up a terrain. I used the options

-create group: yes
-delete original: yes
-merge faces: no
-size 600mm

when it was finished it looked like this

the original terrain had not been deleted. but the new terrain was incomplete where the old mesh was visible (see image above). no idea, why it didnt work. just thought I would tell, in case you have a clue.

Hi,

The smoothing can be done with Matt666's smoothing plugin

@Plot-paris:
Could you PM me the SKP file ? I'm curious to know what bug's still there

@Plot-paris:

Can you show us or share the starting idea, I would like to see before you apply model with contours.(perhaps I've got an idea using your technic to model terrain).

After a few tests using different methods, I let you guess
who's who.

good morning REGIS,

the initial idea was discussed in this thread.

for the who is who test - could you give us some multiple choice answers?

Didier, amazingly useful tool! Thanks so much! Thank you plot-paris and everyone else from this topic for this most excellent idea

[putnik]

Didier, don't know if it's possible to do, but it would be helpful (me thinks) if the the script somehow retained the information collected at the "Parsing terrain.." stage, in case one wants to reshape the terrain again with, say, differently sized triangles.

Hey,

I've imported 6-7 GE terrain meshes, exploded them, put them all in a group, and then tried to run didier's plugin. It didn't come out as expected.
The problem is, i think, that i didn't really merge the different meshes before runnig the script, and that all 6 or 7 of them reacted as independent meshes.
Does anybody have a quick and easy solution for stitching together different meshes imported from GE?

Thank you,


Félix

Hi Felix, I think that the problem is just that you need to select all the terrains you want to reshape and turn them into a single group. Then just select the 1 group and run the plugin. It will not accept a selection of loose geometry. Only a single group.

Hope that helps,

Chris

Suggestion/Request

When dealing with a large terrain surface, the Parsing, Triangulation, and Merging functions of the script can take quite a while.

I was wondering if at the end of each function (before the user goes to the next) if an elapsed time could be shown. At the completion of the script, then a final dialog would be displayed showing the elapsed time of each function.

This way, if you had to convert a series of similar terrains, you wouldn't have to wait around at your computer ... just go do something else and come back according the to elapsed times of the first reshaping session.

effing fantastic plugin. i could have done with this a few weeks back, works great

[plot-paris]

sometimes, when you have got a terrain with a lot of detail in places and very little information in others, the terrain reshaper has to be set according to the highest level of detail. that results in models with unnecessarily large numbers of vertexes.

therefore the idea for an improved plugin - the Dynamic Terrain Reshaper! you define a maximum vertex size and a minimum vertex size. then the plugin calculates the whole terrain with the large vertices and subdivides, where neccessary, until it reaches the minimum vertex size limit.
was that comprehensible?

[Aerilius]

I just used it for a terrain with steep slopes (a vertical rock face). The plugin has much better results than the polygon reducer (which produces many long stretched vertices).

I like your idea much! Maybe the vertex size should also consider the slope.

Didier:
I am inferring that this tool is like a re-topology process. Is that correct?

[plot-paris]

Maybe the vertex size should also consider the slope.

good thinking! could be quite difficult though, because as I understand it, it would differ completely from todays procedure of the plugin (which casts rays vertically onto the terrain). any ideas how it could be done (that the vertex distribution is relative to the terrain normals and not to the top view)?

[mitcorb]

I don't understand "vertex size"? Do you mean the interior angle subtended by its edges? Otherwise, a vertex is a dimensionless point.

[plot-paris]

sorry. I meant polygons.

[theark]

Thank you so much.You make a good change.

[TeKnoel]

I've used the original a few times and it's great for simplifying nasty terrain. Thanks for the update on it!

[SUCCESS01]

how to get it

[Gaieus]

Hi SUCCESS01,

Download it from the very first post of the topic.

[SUCCESS01]

THANKS I GOT IT posting.php?mode=quote&f=323&p=246649#

[lubitel]

I need to eliminate the faces on overlapping terrain patches to be able to make one large clean mesh.

But when I run TR from the menu (after having made the two to a group and the group selected) its not happening....


It does show the "Computing faces area..." in the feedback part of the SU interface....but the pop up window doesn't show up...

What am I doing wrong?

thanx in advance

Thank you very much Didier..... Great Work!!!

please note: I'm going to leave this post as the issues are there but not at all urgent. I'm not pursuing reshaping my terrain because I think it is simple enough and nothing really is going to help it be any other than flat and boring.

I'm getting hangs at 8-9%. Will try with a smaller selection.

With a smaller selection, hang occurs at 85%.

Smaller still, it finishes. I thought I had given it sufficient time but perhaps not. I'll let it run while overnight.
