I planted 150,000 Trees - - - while you blinked.

Hi Folks,





Mixed assets. Predefined planting patterns. Automatically planted in seconds—creating sweeping, shape-based forests that feel natural, organic, and alive.

Regards,
Scott

That looks awesome. Any chance of a video to see it in action?

[frliss]

Looking good. It sure beats the rectangle of TSRE.

Very cool Scott! 😀

Something like this could be a real time-saver compared to doing it by hand.

I'm curious, how does this actually work? I'm assuming something-something OSM data?

Would it e.g. be able to do something like making different areas have different tree types? Let's say, sections of pine tree forest vs normal forest?

[EldoradoRailroad]

Wow,

Not only GenX, but committed to climate change as well.

Beyond useful and very impressive there Scott, would love to see how/what setup is needed for that to blink into view. Are we on our way to have cubic spline grass planting as well?

Great update,
Steve

Hi Eric,

Hah - a video - it's a bit anticlimactic now - when I first had it setup - you could watch the planter threads doing their work - it was hypnotic, enjoyable, and would only take a couple seconds. The subsequent plants in an area seemed to start getting exponentially longer because for every tree planted the display was refreshing all trees planted - so I froze the display until each planting evolution is complete - I've planted up to 150,000 trees on 4 adjacent tiles - and they all go in at around 2 or 3 secconds.

I call it "PolyVeg"...

Hi Fred,

You have now idea - maybe 6 seconds to plant 150K - it's a brave new world.

Hi Peter,

Yep - I modified LIDEX to parse OSM Data while it works on assembling all the maps for a route - saving derivatives as a stacked layers for processing in TSRE. This is nothing new as "Arno" in the Flight Sim world did something like this 15 years ago to populate autogen scenery. I left all the rural land use polys "plantable" by a flood fill - so when enabled - it populates all the same land use classes at once - you no longer need to hunt down each and every occurance.

I use a new JSON schema for defining the used vegetation classes - so you can build a class for Forest, Scub, Wetlands, and even Farmland with crop rows (nod to Eric).

Hi Steve,

Thanks - it's truly amazing and is working quite well - and right in line with my primary goals - faster more efficient route building and improving the look of routes.

Did I mention on my Kaby Lake - I've come up with a means, so 150,000 trees have no discernable impact on frame rate. It's an old Kaby-Lake locked a 60 fps via G-Synch - so it's not a modern supercomputer.

Interesting. Will be curious to see how it works on an older or abandoned route... OSM is current-day data. Working on an abandoned or vintage route might be problematic if the land use doesn't reflect where the historical ROW was.

Just...WOW

Hi Eric,

When I started this - I did not know that OSM Data was so incomplete. There are vast swaths of the US very sparsely populated. I was thinking about how to address this issue. If this happens in an area where you are building a route - I think the best and most efficient alternative - is just go into the Official OSM Editor and make the edits for your route. It's super easy - basically you just trace out simple land use polys in your area of interest - assign a tag for land use type - and upload - they should be available the next day when you download fresh data. I did a couple dozen as a test and it works well - still providing a real-world randomness that is VERY HARD to match by hand placing trees in TSRE. Plus, you help the OSM community at the same time.

Secondly - I added a new ruler tool that can use the same fill methods as OSM data - that you can make a linked path with a user defined width - or another option where the ruler forms polys automatically connecting back to the first point.

It seems to be working EXTREMELY well - I am stopping at this point to get back to 4m terrain tiles - as you mentioned - if the textures are not being applied correctly on 4m in ORTS - I think that is an issue James needs to address - I will start making sure all the other tools in TSRE work for 4m as well.

Hi Rick,

I impressed the master - hah - that means a lot.

Hi Folks,

Oh - and the tree planting honors exclusions for urban areas, road, track, and water in OSM - - - and TDB and RDB entries as well.

And ski slopes too.
