Moved large examples/ folder from inst/ to data-raw/ to avoid it being installed.
Remove failing test comparing unimportant differences in geocentric transformation.
quadmesh now works with upcoming release of reproj (> 0.4.0).
Fixed failing CRAN test by internalizing use of hcl.colors().
mesh_plot() now has a method for mesh3d. Intention
is to use mesh3d as the common basis for mesh_plot().
WIP new use_crs() facility to set the projection in
use when setting up a mesh_plot. Subsequent calls to
mesh_plot(, add = TRUE) will automatically project to the
coordinate system in use. use_crs() will set or get the
PROJ string.
mesh_plot() now has a method for mesh3d. Intention
is to use mesh3d as the common basis for mesh_plot(). Now using palr
package for colour handling.

New feature in quadmesh() to auto-expand a palette
raster to the required RGB brick for the texture argument.
Motivated by
https://gis.stackexchange.com/questions/324552/creating-3d-image-from-hgt-files.
Simplified use of reproj() by relying on upcoming
new version.
Function mesh_plot() now handles stars objects, only
plotting the first x-y slice.
mesh3d creation, partial naming of
material$color caused various problems.Function mesh_plot gains zlim and
passes ... to base::plot() (for aspect ratios
with wildly disparate dwide/high grids).
Now using the reproj package for coordinate
transformations.
New mesh_plot() method for TRI objects
from silicate/anglr.
New function dquadmesh to provide the discrete
interpretation of a grid.
New function bary_index to provide a basis for
interpolation of a regular grid from triangles.
New functions triangmesh() and
dtriangmesh to provide the triangle-interpretation of a
raster (bound to centre coordinates).
quadmesh() is now generic with a new method for
‘matrix’.
Some fixes and additional features for mesh_plot()
to allow plotting with curvilinear coords.
New function qm_as_raster to round-trip to a
RasterLayer.
The z argument of quadmesh() may now
have a different coordinate system to the input data x. The
mesh coordinates of x are silently reprojected if needed
and used to extract values in the native coordinate system of
z.
A new qsc function to return a very simple six quad
rendition of the Quadrilateralized Spherical Cube projection
family.
The mesh_plot function gains true curvilinear grid
support by allowing input of coords, a two-layer raster of
longitude and latitude values for the cell geography. This aligns with
the approach used in the angstroms package.
The quadmesh function gains a new argument
‘texture_filename’ to control the output PNG file.
The quadmesh functions gains a texture
argument, to map on a 3-layer RGB raster (in 0-255) via a temporary PNG
file.
New function mesh_plot for basic vectorized raster
plot with optional near near-lossless projection
transformation.
Index arrays are now created with integer mode.
Added triangulate_quads function to convert quad
index to pairs of triangle index.
Added supporting information to package.
Internal function llh2xyz is now exported to
transform from longitude latitude coordinates to geocentric xyz
coordinates.
