This program takes in a volume-less 3d tree skeleton, and a set of parameters and creates a voxel representation of the skeleton, with smoothly blended junctions, and correct thickness of branches.
This is done by running a series of implicit line primitives along the skeleton. These primitives collide and blend with one another, thus building up the thickness of the branches lower on the tree.
This Program has only been tested on Linux. imagemagick is required for screenshotting
To Build: create a build folder, and run cmake .. and make while
inside the build folder.
To Run: execute ./tree_strands <options.json>. You can find a set of
pretested options.json files in resources/options. If you would like to
tweak the options, you can do so directly through a text editor, or using
the tree_panel program
Once the program completes generating the tree you can look at it by moving the camera with the keyboard.
- WASD -> Panning the camera
- IJKL -> Rotating the camera
- UO -> Zoom in/out
- R -> Reset Camera
You Can also toggle the various display modes by using the number keys.
- 1: The tree model
- 2: The scalar field generated from the implicit primitives
- 3: The strands that define the implicit line primitives
- 4: The normals of the tree model surface
- 5: The input tree skeleton
