Simple stylish 3d tree object?

Mats_Knutsson — Wed, 31 May 2023 07:51:59 GMT

Hi, what would be the best geometry to program a simple 3D tree kind of the examples in attach?

I'm looking for something with parameters that I can randomize to get a slightly new geometry for each instance.

Br,

Mats

Hm... That reminds me of the Rock Quarried object in the CI Essentials library, just need to put it on a stick, like what the default AC trees can do.

In the GER Library there is a Concept Tree object which is not that simple, but tweaking it's settings does allow to get similar results.

There is an extensive Tree Library available at ArchiRadar, which do have low poly options integrated, but I never used those and I don't know how they look like.

https://www.youtube.com/watch?v=b5_QGzv6RHQ&t=1493s the library / object linked in the video description will allow you to make something sort of similar.

There are some preset trees that you can change to use sphere shapes instead of warped planes, maybe lower the amount of shapes generated and change the surface material to something solid.

This is what came to my mind as well

Some quick try:

It looks more than rendering results than 2d section/elevation. Nice artistic shape. Maybe you can do it with png.

Massivator trees can look nice, but they are slow... =S

Have a look at the first 'panel' in the settings. That's where the amount of leaf objects are generated. You can try cutting the numbers in half to see if the results are still good enough.

It's going to look like an abstraction of a tree regardless, so I ussually go for a bit of artistic license. Then again, I'm no botanist, so I tend to go for 'good enough' quickly 🙂

I had the same problem, so I built one 😀

It was one of the first objects I built for Archicad, and it is unfinished, but should be usable as a starting point.

I was inspired by the simple massing geometry that Google Earth uses. It ought to be possible to get a good foliage texture to map to this so it looks like a GE tree.

The 2D symbol is quite nice too, and I have some alternative options that can be used.

I can provide the actual source geometry if anyone wants to take this further.

Whatever they do - I would ask that it be made available to everyone for free.

I can upload them to Google Drive and post a link.

I'll see if I can do some more to it in the next couple of days before I go on leave for Christmas, but there are lots of people here who would do a much better job!

Here is the link to a pln file with an initial object and the raw geometry.

Mats is looking at making some objects over Christmas.

His wife will be happy...

I looked at the code but didn't understand it. Instead I played with another concept... Treetime . Needs a few more tweaks.

EDIT. I tweaked a bit https://youtu.be/kZG4XRIMGXE ... I skipped gym. This was more fun. Doing progress but still looking lollypoppish... got the rgb but will probably use a handful of chosen rgb's not to be surprised by ugly colors....didn't get masking out contours (when they are checked in 3D styles).

The massivator is cool. I've tried it. I think I'm close in something further dow in this thread.

Hi Miha :). That object looks interesting. Mind sharing it? We should have the same libs as germany but obviously not... /Mats

I was on the same search a while back as I lacked a suitable low poly tree/hedge object for site models / scale reference. I'm currently getting by using the in AC simplified geometry from Escape assets (example here) which lacks parametricity.

I came across this app from Dr. Andrew Marsh which is truly awesome with an effective and intuitive approach to geometry generation. Unfortunately it is provided under a non-commercial license, and I haven't been able to get in contact regarding possible commercial use.

Re: Simple stylish 3d tree object?

Jim Allen — Fri, 16 Dec 2022 12:02:46 GMT

Andrew Marsh builds some fantastic tools, but his complex trees will be too heavy in terms of polygon count, and you can get better results from something like NGPlant. I've built lots of realistic plants with that, but poly count is an issue.

His simple trees might be ideal though.

Hi! Its a long shot since its an old post but do you have any recent links which I can use? This image is exactly what I am looking for in Archicad! 🙈 Cheers!

Re: Simple stylish 3d tree object?

Jim Allen — Tue, 11 Feb 2025 15:10:14 GMT

How about this?

Happy to share the gsm file. It has a 2d representation (simple shaded circle) and a 3d one.

As with all my GDL objects - modifications/improvements are actively encouraged!

Re: Simple stylish 3d tree object?

Jim Allen — Thu, 13 Feb 2025 16:10:46 GMT

Object attached.

It could be improved with better hotspots (particularly for scaling in 3D) and making the object scaling more consistent between the 2D and 3D elements. They are kind of okay, but I'm not very good with hotspots!
