anglr 0.8.0

  • Fixed bug in 'DEL0()' that neglected subclass 'DEL0'.

  • Fixed bug in 'globe()' that was garbling the vertices.

  • Fix auto-triangulation of sf objects, these now become meshes as per their native type.

  • Update as.mesh3d() to generate quads, triangles, segments, points as appropriate (not complete).

anglr 0.7.0

  • Removed rgdal dependency.

  • Use dpylr::summarise() not tally() to avoid dplyr warning, thanks to Romain Francois (#152).

  • Bug fix (avoid warning) for degenerate dimensions with matrix input to as.mesh3d() (#142).

  • Bug fix in triangle colouring for grids (#143).

  • Now importing colourvalues to convert RGB to hex for mesh_plot().

  • New internal function texture_mesh3d() adds support to mesh_plot() for approximate face colouring based on a texture, wish of #90. Is named after 'palr::image_raster()' etc by "what does the colouring"_"what is the output". Experimental.

  • New sp polygons data set cst10 for exploring precision issues.

  • plot3d() now works for sf POINT and MULTIPOINT (no control with object$color_ but usual plot3d properties can be controlled.

anglr 0.6.0

  • Fixed DEL0() for polygons. #138

  • Checks for alignment to dplyr 1.0.0.

  • Fixed raster and new projection handling problems.

  • Fixed missing github links.

  • Now importing terrainmeshr, for experimental hmm support (efficient conversion of raster to triangles with triangle density where needed based on curvature).

anglr 0.5.0

  • Fixed beginning of Description, thanks to CRAN feedback.

  • Changed behaviour of auto_3d(), now simply an alias to rgl::aspect3d(1) and any previous used arguments now ignored, with a message.

  • Tightened up behaviour of QUAD, being lazy and copying down the z.

  • Remove non-ascii columns (and others) from 'simpleworld', thanks to help by Michael Chirico @michael_chirico.

  • Align to obscured bug fix for silicate, #119.

  • Fixed mesh_plot() default colours for a textured mesh.

  • mesh_plot() now correctly reprojects a mesh to a crs argument, or accepts coordinates for a plot with coords argument.

  • Replaced data set gebco1 with gebco, a cleaner version derived from GEBCO 2019, at 0.5 resolution and stored as integers.

  • Added degenerate path surface interpolation (i.e. triangulation for POINT or MULTIPOINT with xy, xyz, xyzm, or xym), wish of #115.

  • Bug fix, now correctly culling invisible triangles for 2D and 3D plots of DEL and TRI models, as was working for DEL0 and TRI0 (because they don't store invisible triangles).

  • Now providing the full suite of mesh plotting functions from rgl. plot3d(), dot3d(), wire3d(), and persp3d() now work with matrix, raster, sf, sp, trip, RTriangle, and silicate models. Each of the mesh-surface forms rely on as.mesh3d() conversion behind the scenes, whereas plot3d() on linear types (sf, sp, trip, silicate SC, SC0, PATH, PATH0, and ARC0) all are plotted using rgl segments without going through a triangulated surface form.

  • as.mesh3d() has been completely rebuilt, to consolidate code from quadmesh and angstroms on a firmer basis. as.mesh3d() now understands all of the surface types from sf, sp, raster, and silicate, and can accept a raw matrix as input. It can also include a z argument to extract elevation values from a raster, and an image_texture argument to drape an image from a raster RGB object onto the surface. Map projections are automatically resolved to the coordinate system of the x argument (as much as possible, there are lingering issues with the ongoing changes to crs in PROJ library, and the reproj and proj4 packages which attempt to smooth over the changes in Spatial and sf and raster objects.)

  • QUAD() is now exported but still considered experimental.

  • Added experimental DEL0() model.

  • Now importing crsmeta, to get sf crs '$proj4string' or '$input'. If input is not a proj4string then we'll burn. (Can do manual reprojection until PROJ is here).

  • Removed QUAD, hopefully temporarily.

  • Support for rgl's plot3d and as.mesh3d is now greatly improved, and now tmesh3d() and qmesh3d() are used rather than creating these types manually.

  • Now using reproj package instead of proj4 directly.

  • New data sets, cad_tas and cont_tas.

  • Old anglr() function now defunct.

anglr 0.4.7

  • Added a TRI method for QUAD.

  • DEL.SC now removes duplicate vertices like DEL.PATH always did, but triangulation is still done per object since we don't yet have edge to path logic required for object classification within the mesh.

  • Improved the triangulation and triangulation to edges logic.

  • The plot methods for QUAD now maps cell value to colour.

  • new QUAD model, for raster data. By default the raster cell values are treated as a fill aesthetic, and used to provide colour on a flat mesh. The copy_down method for a QUAD requires only one argument will put the cell values on the geometry for z_. This separation is required especially for more general geometries like XYZ geocentric, because the cell value and geometric Z are not necessarily related.

  • Now re-exporting the magrittr pipe.

  • Added gebco1 as a built-in global elevation data set, to avoid reading from GeoTIFF.

  • Internal function anglr_lines is now deprecated, and points to the silicate and plot3d approach.

  • Added copy_down generic to dispatch on sc and subclasses, to
    transfer raw values, object column data, or raster values to vertices.

  • Added plot3d methods to (eventually) replace plot(anglr(x)) and linemesh with plot3d(silicate_model)- currently onlySCsupported and plots as (object-grouped) edges. Returnsrgl` form silently.

  • Removed use of maptools wrld_simpl, replaced by in-built simpleworld.

  • Big update for new silicate-based approach, thanks to Andreja Stojic for the feedback.

  • New approach for polygons now using pfft package, identifying triangle centroids by polygon.

anglr 0.4.6

  • new "z = " support in anglr for a feature name (to copy as a constant) or a raster object (to extract values onto vertices), for now the raster must be in the same coordinate system as the input object

  • new add_normals argument for plotting triangulations

  • rename package (from rangl)

  • now faster by relying on silicate for sf

rangl 0.4.5

  • release codename Just Work in Master, Dude

  • old functions made defunct

  • points now have meta table (it was missing), and singular points are now supported

  • raster package is now an Import

  • added support for RasterLayer

  • fixed globe to keep PROJ.4

  • quashed a major bug introduced by use of dplyr::distinct, best to use factor unique classifier on character versions of coords

  • several cleanup fixes

rangl 0.3.0

  • rename again, main function is called 'rangl', the term 'mesh' is too often used across R

  • rangl method for trip

  • fix for spbabel now means MultiPoints are rangl()-able

rangl 0.2.0

  • removed old globe() plot behaviour, this function now just converts coordinates to geocentric XYZ

  • added generic "mesh()" function to convert SpatialPolygons, SpatialLines, and rgl 'mesh3d' objects (only those that use triangle primitives)

  • deprecated "tri_mesh" function, replaced by mesh()

  • renamed package to 'rangl'

  • improved code coverage of tests

  • infrastructure and tests for globe

  • new function globe

  • performance improved for hole finding and removal from mesh

  • achieved working package scaffolding

trimesh 0.1.0

  • first release to Github
