Changes in version 2018-12-20 - na.rm=FALSE bug and add_overlay issue fixed - Fix add_overlay dimensions when no transparency layer present Changes in version 2018-12-14 Additions - Updated plot_3d to draw NA entries in the elevation matrix as holes in the 3D model. This can be used to slice the model into any shape. - Updated plot_3d to include the new baseshape argument, which has several built-in shapes c("circle","hex") to overlay onto a matrix. This removes points in the elevation matrix outside the masked region. - Added lineantialias option to plot_3d to allow the user to turn on antialiasing for the lines in the plot. Changes - Removed shadow_exist and remove_water options from save_3dprint to improve robustness. User now has to remove those 3D elements themselves when creating .stl file. - Fixed add_overlay when the input is a matrix - Updated documentation for plot_3d with examples. - Fixed reference to save_png in README Changes in version 2018-11-21 Additions - Added render_label() function to add text labels to 3D plots. Changes - Updated README - Fixed all progbar arguments to be either FALSE or interactive() by default Changes in version 2018-11-08 - Changed progress bar to appear only when the user is in an interactive session (thanks @hadley) - Fixed bug with water edges not following non-zero water depth - Cleaned up documentation Changes in version 2018-10-27 - Speed improvements for 3D rendering with plot_3d - Fixed small gaps and overlays in rendered water and edge lines in plot_3d Changes in version 2018-10-25 - Implemented binary search for intersection, massive speed increase for ray_shade() - Moved Rcpp::checkUserInterrupt() to outer loop to speed up raytracing (thanks @brodieG) Changes in version 2018-09-23 Additions - Added render_depth(), a post-processing effect to add depth of field to 3D maps. - Added render_water(), which either adds or replaces a water layer on the existing 3D map. - Added add_overlay(), which adds a transparent or semi-transparent overlay to the current hillshade. - Added attribute to montereybay to mark it as internal data (for better user messages) Changes - Changed save_3dprint() to include the option to remove the shadow and water layers. Changes in version 2018-09-20 - Altered coordinates of plot_map to align with the center of the grid Changes in version 2018-09-18 - Fix for add_water hex color bug Changes in version 2018-09-16 - Fixed aspect ratio in plot_map() Changes in version 2018-09-06 Changes - Fixed out-of-bounds bug in C++ normal vector generation - plot_map() no longer crashes R when "rotate" is a matrix rather than a single numeric value. - plot_3d() now displays warning if hillshade argument contains any values below 0 or more than 1. Changes in version 2018-08-25 Additions - Added save_3dprint, a function that exports 3D maps to a stereolithography (STL) format for 3D printing. - Add hex logo to README Changes - Fixed small overhand on 3D base. - Changed write_png to save_png - Corrected orientation of polygons in plot_3d Changes in version 2018-08-24 CRAN fixes - Fixed lack of examples in some functions for CRAN and changed \dontrun{} calls to \donttest{} Changes - Removed remove_edges option: the x/y dimensions of the outputs and inputs are now always consistent. Changes in version 2018-08-20 - make_shadow bugfix Changes in version 2018-08-17 Additions - Implemented custom C++ version of akima::bilinear.grid to remove non-GPL software dependency - Add ability for add_water to work with matrices Changes - Turn off examples for plot_3d - Fix issue with non-exporting internal Rcpp functions to foreach - Added description to ray - Update DESCRIPTION Changes in version 2018-08-16 Additions - Added shadow color option Changes - Fixed background color to blend in with shadow - Fixed description of error in sphere_shade - Small updates to documentation Changes in version 2018-08-09 Additions - Added default settings for zscale when montereybay dataset used and zscale is not passed in by user Changes in version 2018-08-08 Additions - Added example dataset montereybay Changes in version 2018-08-06 - Update pipe import from magrittr Additions - Added plot_3d, a function to take hillshades/textures and visualize them with an elevation matrix in 3D. Includes water visualization and the ability to view the map as a solid object. - Added zscale argument to detect_water. Changes - Changed default orientation to match the orientation of the matrix. - Changed detect_water and calculate_normals to not show a progress bar by default. - Changed ambient_shade to default to 1-45 degrees, instead of 0-45. - Changed write_png to stop when user doesn’t provide a filename. - Updated README Changes in version 2018-06-30 - ray_shade and ambient_shade - Added option to pass arguments to makeCluster function for parallel execution Changes in version 2018-06-28 Additions - Added sphere_shade function to apply spherical texture maps to elevation matrices. - Added create_texture function to allow user to programmatically create texture maps by specifying colors. - Added ambient_shade function to calculate ambient occlusion shadow maps. - Added add_shadow function to add shadow to existing shadow matrices/texture arrays. - Added calculate_normal function to pre-calculate normal vectors of elevation matrix for faster spherical shading. - Added detect_water function to automatically detect bodies of water (of a specified size) on an elevation matrix. - Added write_png function to save hillshaded maps to file. - Added plot_map function to parse and plot resulting hillshaded maps. - Added the ability to add a mask to raytracing and ambient occlusion so only certain areas are raytraced. Changes - Changed names of functions to be snake_case. - Various bugfixes Changes in version 2018-05-20 - Out of bounds memory bug fix Changes in version 2018-05-19 Additions - Added Lambertian shading by default to the rayshade function. - Added standalone lambshade function. - Added progress bar support. - Added option to remove edges. Default TRUE. Changes - Changed angles all to degrees instead of radians. - Removed verbose option. Changes in version 2018-05-13 - Initial commit.
