Groundhog
ADDON. Version 0.13.0. Released on 24-May-2021. Provides 25 components. Created by Philip Belesky. Features 0 video tutorials.
Groundhog is a Grasshopper plugin, a set of reference models, and wiki exploring the applications of computational design in landscape architecture.
Hydro
| Channel Region (CRegion) Determine the submerged region of a channel given a quantity of water | |
| Channel Info (CInfo) Calculate characteristics of water flow in a channel from its submerged region | |
| River Flood Levels (River Floods) Examine flooding levels along a surface from a river source | |
| Sea Flood Levels (Sea Floods) Examine flooding levels along a surface from a tidal source | |
| Flow Saturation (Saturation) Identify the saturation levels across terrain given flow paths | |
| Flow Catchments (Catchments) Identify the catchments within a set of flow paths | |
| Flow Projection (Mesh) (Mesh Flows) Construct flow paths over a mesh | |
| Flow Projection (Surface) (Srf Flows) Construct flow paths over a surface |
Flora
| Generic Species (PGeneric) Output plant objects from pre-defined generic types | |
| Species Importer (PImport) Create plant attributes from an imported spreadsheet | |
| Plant Appearance (root mesh) (Shower (root mesh)) Simulate the appearance of a particular plant instance's root using a mesh between canopy and trunk | |
| Plant Appearance (canopy mesh) (Shower (canopy mesh)) Simulate the appearance of a particular plant instance's canopy using a mesh between canopy and trunk | |
| Plant Appearance (discs) (Shower (discs)) Simulate the appearance of a particular plant instance using circles |
Mapping
| Field Mapper (Field) Create a field representation from collections of bounded curves/lines. | |
| Field Visualisation (Grid) (Field Grid) Translate a field into a grid based visualisation. Outputs a number constrained by a range which can be used to then make a color or shape. | |
| Random Path (RandPath) Calculates a random path (in 2 dimensions) | |
| Shortest Path (ShortPath) Calculates the shortest path in a network of curves |
Utilities
| Contour Gap Fix (Contour Gaps) Checks if contours have gaps, and bridges them if so | |
| Contour Planarity Fix (Contour Planarity) Checks contours are planar and corrects them if not | |
| Contour Clipper (Contour Clip) Checks contours meet a specific boundary, otherwise extend/trim them | |
| Mesh Color by Face (Mesh Paint) Colors each mesh face with a solid color, in order. Like mesh spray, but without any blending between faces. |
Terrain
| Mesh Aspect (Aspect) Analyses the aspect of a Mesh, outputting separated faces for coloring and the aspect | |
| Mesh Slope (Slope) Analyses the slope of a Mesh, outputting separated faces for coloring and the slope/grade | |
| Surface Aspect (Aspect) Analyses the aspect of a Surface, outputting separated faces for coloring and the aspect | |
| Surface Slope (Slope) Analyses the slope of a Surface, outputting separated faces for coloring and the slope/grade |
