Find yourself needing a terrain mesh with more detail? Or a larger area than Geo-Location allows you to import? If so check out Eric's process for turning 2D heightmaps into detailed 3D terrain meshes.

Wow, that's really nice I'm going to use that to model my bungalow so I have a realistic topography around it showing the views we have. Thanks Eric for the clear instructions and links.

@ericsargeant3254 Год назад

Coo! Let me know how it turns out.

@Skans-Gustav Год назад

I saw and used this on youtube maybe two years or so ago, but this was a nice reminder to maybe use it again.

This is awesome! Thanks for sharing this process

Thank you for the hight mal tip!

Point Dume ❤ I always see dolphins when I’m there. Great tutorial!

Amazing

@JohnRodriguez-gl1hk Год назад

This is a game changer. Thank you so much. How accurate are the height maps for elevation?

@ericsargeant3254 Год назад

There is no 'elevation' data with a heightmap. Whit = up...black = down. That's why I showed how to use the GeoLocation Terrain as a height reference - scaling the heightmap terrain mesh by its vertical tab

Hi Erik, congrats on the video! One question, tho: what’s the best practice for modeling terrain on SketchUp for iPad? Thank you so much for your help! I’m sending you the best vibes from Brazil! 🌼

@ericsargeant3254 Год назад

Hi. Thanks for the good vibes. Modeling terrain for iPad not as easy as it is on the Desktop version given the lack of extensions. Even Sandbox tools function like an extension. So hopefully support for at least Sandbox Tools comes in a future release.

@3DGvisuals Год назад

That's really useful to know, thanks. However, I really think this just shows that some of the native tools really need to be upgraded as this should be how the geolocation tool looks in terms of quality.

@ericsargeant3254 Год назад

The data for both the aerial and terrain mesh come from an outside provider...while GeoLocation is native, the data is not... But that said, the DigitalGlobe/Bing data works well for most users needs.

@3DGvisuals Год назад

@@ericsargeant3254 if it was still owned by Google rather than trimble I suspect this native feature would be far in advance of what it is.

@jesperfuglsang Год назад

It doesn't seem to work in smaller countries...

@jesperfuglsang Год назад

Question: To make sure your texture/reference photo is the exact same as your height map where did you get it? If it's not the exact same then you can't scale exactly or paint your height map so it matches. Does my question make sense :D

@ericsargeant3254 Год назад

Your question makes sense. I used Photoshop to overlay the heightmap and the Aerial so they lined up. Then saved both the aerial and heightmap from there so that they have the same proportions/dimensions. The Heightmapper site allows you to export with and without labels/borders. I used the labels version to help align to aerial, then saved the version without at 250 px for importing via bitmap2mesh.

@jesperfuglsang Год назад

@@ericsargeant3254have you tried to import height maps from outside of the States. I have tried from Denmark, and there seems to be issues when to zoom in :(

@ericsargeant3254 Год назад

@@jesperfuglsang Seems to show up/work for me. Try posting this same question to our forum - forums.sketchup.com/ and I can help you better. Be sure to use @eric-s so that I see it ;)

I cant seem to get it to show in my extensions. It says its installed but still cant see it? Windows SKUP 2023 pro

@craigmeadow2928 Год назад

Sorry I guess it pays to watch the video LOL got it "go to Draw "

@ericsargeant3254 Год назад

@@craigmeadow2928 Oh good you found it. Yes it's not in the 'normal' extensions dropdown menu. Every extension works a little different don't they?

@bm7878 Год назад

how can I import the same area? THK

@ericsargeant3254 Год назад

Just follow the steps. Install the extension. Grab the height map after finding it Point Dume in Malibu, CA. Downsample resolution to 250 px. Then import using Bitmap2Mesh and bam!

@cekuhnen Год назад

I work with drone high res scans and for this found sketchUp unusable and rather do that modeling in blender or shapr3D

@ericsargeant3254 Год назад

That's a bummer as I've imported huge drone photogrammatry meshes and images and works for me. Let me know if you ever have specific questions and I'll share more on the process.

@cekuhnen Год назад

@@ericsargeant3254 hmm maybe I made a mistake - what format do you use when importing and how big are the models ? My scans are between 200mb to 1gb
