[Plugin] TopoShaper - v2.5a - 16 Feb 19 - IsoContour & Cloud

[fredo6]

The information on TopoShaper is maintained on the Plugin Home Page of TopoShaper. This is also where you can download the RBZ file.

Requirement: LibFredo6 v8.7a or above

IMPORTANT: please upgrade to v2.5a or above if you run SU2019


If you land on this page and are unfamiliar with how to install Sketchup Extensions such as LibFredo6 or how to register on Sketchucation, please watch this video or refer to the Plugin page of LibFredo6.

TopoShaper generates Terrains:

• from a group of iso-contours, that is, contours which have a constant or quasi-constant altitude. The Terrain is generated as a QuadMesh
• from a Cloud of Points (given as a group of Guide points). The Terrain is generated as an adaptive Triangular mesh.

TopoShaper::IsoContours
TopoShaper::IsoContours works in 4 steps:

• Selection of Contours , usually by pre-selecting a group containing the contours before launching TopoShaper
• Cleansing Contours, which can be useful when contours are imported as DXF/DWG files. In version 1.0, the Cleansing covers the exclusion / inclusion of contours, their simplification, automatic and manual junctions and removal of small hooks. There is an Altitude Editor to set or modify the altitude of the indivdual contours.
• Calculation of Terrain and Preview. The Terrain is computed on a rectangular grid. You can change the grid resolution and have option to configure the hilltops and basins.
• Generation of the Terrain Surface as a quad-mesh surface enclosed in a group. Optionally you can include the Skirt and the contour map, with or without altitude labels.

The idea of this plugin was developed after some discussions in another thread initiated by Brookefox. You will also find there some models of contours to exercise TopoShaper.

Here are [url=http:http://sketchucation.com/forums/viewtopic.php?f=323&t=52039&p=513310#p513310]a few sample contours models[/url] from some kind Community users. This will help you to get familiar with TopoShaper::IsoContours.

TopoShaper::PointsCloud
TopoShaper::PointsCloud takes a group of Guide Points. If it encloses faces, they will form the Clipping Contours. Otherwise, the default Clipping contours are taken as the convex hull of the points.
The Terrain is generated as an adaptive triangular mesh, where triangles are more dense where the altitude changes. The algorithm is iterative, by refinement of the triangulation until the Terrain is 'smooth' enough (specified by a smoothing angle). Points are part of the mesh (i.e. the terrain passes thorugh the original points).

Just drop the attached PDF files into the DOCUMENTATION_Dir sub-folder to have it accessible from within Sketchup.

There is also a service API for calculating silently a Terrain from isocontours. Here is the documentation with examples:

BOOOOM! Goes the Dynamite!

[wyatt]

Awesome! Can't wait to try this out.

[alpro]

Thanks fredo, looks like another amazing plugin !

[Jpac]

Thank you so much Fredo! It's amazing and exactly what we need working with topography.

[cotty]

Another classic from you, thank you!

[pbacot]

WOOHOO. Pass the champagne! I just got a project to run on this one. A nice STEEP slope.

Thanks a million times, Fredo.

Thanks for the toast! If you encountered problems on your new model, do not heistate to send it to me so that I can investigate.

wow, when Master Fredo comes down from the mountain (literally in this case), he always come back with some incredible treasure...

awed and grateful thanks!

Wow! This looks great. Can't wait to try it out!

[plot-paris]

Yet another magnificent plugin to greatly enhance SketchUp's usability. And again to the highest standards!

How easy it is to repair (automatically AND manually) faulty terrains! Amazing!

Fredo, you outdid yourself once again!!! (initial Donation already made...)


@CadFather:
thanks for the shiny buttons!

[thomthom]

Just had a look through the manual for the full breakdown of this plugin - ZOMG! This must have taken time to develop! Why you don't release this as a commercial plugin is beyond me.

I would encourage people to use the Donate button to reward Fredo for the amazing effort on , not only this plugin - but his whole suite!

Thanks very much. I am always impressed by your quality of designer.

If you don't mind, I'll integrate them into the next release as the standard icon.

It is some work indeed, but I do it on my spare time. This is why it takes so long (6 months elapsed). And as usual, this is 80% GUI and 20% algorithmics.

the donate button in Sketchup sends me to a paypal link that seems to be in French and won't let me login. I'll just send it to the email address.

I posted those pictures and didn't know similar ones were already in the instructions. I'm SketchUp famous now... Such an awesome feature to "fix" the topo map.

NEW RELEASE: TopoShaper v1.0b - 26 Apr 13

This is an adjustment release with afew evolutions:

• Integrated the Spanish (oxer) and Chinese (guanjin) transaltions. Thanks to both.
• Integrated the toolbar icon proposed by Cadfather. Thansk very much too
• Added the generation of 2D contour map geometry
• Fix an issue with architectural units in the dimension dialog box

See main post of this thread for Download.

..my honour Fredo. anytime, just ask. (and thanks again!)

[ly871108]

I'm a Chinese.The Chinese version by GUANJIN is too bad.You know,he is famous for translating by Google translation which called machine translation in China.Just for perfunctoriness and money.He owns a forum which the plugins translated in Chinese by him are sold.Your plugins are so good,so that,We must put quality before quantity.We would rather go without than have something shoddy.I beg that you should find out the truth.I swear that all I said is true.THANK YOU.

Topissime!

Thank you Fredo! Your have your own SU inside SU. All great plugins.

[tald311]

Awesome!! Really awesome. Thank you.

[notareal]

Another stunning plugin! Thanks, Fredo.

as ever...

[EarthMover]

Plugin of the year for me. Been checking in consistently to see if it was released and then today just happened upon it in the Plugin Store from within Sketchup. (Thanks Rich!!!)

Thanks for putting the time and effort into this Fredo. Can't be happier and will definitely donate for this one! You are the man!!

[pbacot]

Well I had no problem whatsoever with my first trial. This image doesn't do full justice to the model and what I hope to do with it, but I needed these sections first and it was a pretty quick and painless with SU and LO to make this sheet (Low res here for SCF). And Toposhaper... I just clicked and boom it was done-- I raised the grid resolution up a ways (perhaps ridiculously high) and no problem. Made some "groups from sections" and made overlapping scenes in LO. All from a 2d plan (I had a tool in PowerCADD to give the contours elevation).

Thanks Fredo!

A good occasion to donate on.

[utiler]

Well done, Fredo. You are the master!!!

ching ching!

[andybot]

Wow, absolutely, amazingly, WOW!! What an amazing job Fredo, thank you x1000!!
