SO: Decided to tackle this project. Biggest thing to overcome is the fact that google maps height data is hopelessly innacurate and the scan data 5m is hopeless too big, with the further issue of the scan is with trees, and as the arch over the road even worse. BUT. going to try anyway. I already own 3dcoat and never thought about using it to bash down the size of the scan data (false economy, because I will be trading heavy mesh for heavy voxel mesh, but, at least once its all in one place in 3dcoat I can trim away the bit I dont need, then decimate back to tri mesh), quick test last night says it will get the job done in about 8 hours on my dual xeon machine. (15 minutes per tile to import and voxelise). The machine has 128gb of ram so if i trim on a per tile basis as each tile imports i think i will have JUST enough ram to pull it off.
I will go out super early and ride the 14km section between waterfall entrance to stanwell tops a few times in both directions to get a LHS and RHS curve to the road. my home built gps/obd logger also logs g-force shifts. Started the work on writing a plugin for rhinoceros3d to take all that info and spit out two curves that can be used to sweep2 a track including bumps. Idea being if i then import the decimated mesh from 3dcoat to rhino I can match the earth to the track then take the whole lot as two layers into 3dcoat and smooth down the trees at the road verge to replace with modelled trees.
Now the question to
@Teddie and maybe @p4cker0wns, is there a decent set of trees you guys have as a resource for this kind of project, as presumably i will be working completely outside of RTB they are needed as FBX or even obj/3ds etc for placement in 3dsimed.
-OR-
Is there a workflow to bring the whole mesh into RTB and place trees on the mesh inside RTB? (and then repeat request, x-packs of decent trees?)
@Lernatix did you look at the scan data resources, there is a TIFF resource that is an image instead of this huge mesh, and from what I can tell its "bare earth", but, I have no idea how to turn that back into a mesh or scale to correct sizes etc. Any software you can recommend for working with those geoTIFF files?
The whole thing about the nasho is those trees, and if not done right will loose all impact. (see vid of trees inoriginal post)
