⁠3D Terrain Modelling

This tool will create a 3D model in Blender given a set of GPS coordinates. This is still a work in progress, so not all of the steps are automated yet.

I built this primarily to take a GPX route from a hike or four wheeling trip and create a full color, printable 3D model.

⁠Workflow

This is the typical steps that I follow to create a new model. All of these commands are run inside the container, with a host directory mounted at "work" to hold the input/output files

1. Create the X3D model

./build_model.py --gpx-file work/hitw.gpx \
                 --padding 0.2 \
                 --model-file work/hitw.x3d

1. Download orthoimages from The National Map⁠
2. Crop the image(s)

./crop_geophoto.py --gpx-file work/hitw.gpx \
                   --padding 0.2 \
                   --output-file work/cropped.tif \
                   --input-file work/m_3911925_se_11_1_20150616_20150923.jp2 \
                   --input-file work/m_3911933_ne_11_1_20150616_20150923.jp2

1. Overlay the tracks onto the image

./draw_track.py --gpx-file work/hitw.gpx \
                --track-color red \
                --track-width 10 \
                --input-file work/cropped.tif \
                --output-file work/hitw.png

1. Import the X3D model into blender, add some thickness to it, UV map the image onto it, export it and upload to shapeways⁠ for printing
