ggcube 0.3.0

Changes to default behaviors, which slightly alter styling relative to prior version:

• coord_3d() now draws axis ticks by default, whereas previously axis ticks were not implemented. They can be removed or styled with the standard axis.ticks and axis.ticks.length theme elements plus a new axis.ticks.z.
• Axis text now gets depth scaling, i.e. perspective-based sizing, by default. (Axis titles remain unscaled.) You can use coord_3d(scale_depth = c(text = FALSE)) to opt out.
• Axis text and title placement is now computed at draw time from measured text dimensions. This fixes inexact size estimates that previously sometimes led to text overlapping titles and/or axes on small devices.

New options:

• Lighting can now be set for a whole plot by adding light() to it, e.g. ggplot(...) + coord_3d() + light(direction = c(1, 0, 0)). This is the recommended way to specify plot-level lighting, and works regardless of where it appears in the plot expression. The light argument of coord_3d() continues to work; supplying both is an error.
• light("none") is a new way to disable lighting, equivalent to the string "none" accepted by light arguments.
• scale_depth arguments are now more customizable: in 3D layer functions you can now pass continuous values to reduce or exaggerate the effect (rather than just a logical flag), and in coord_3d() you have more granular control over scaling for gridlines, ticks, and axis text.

Bug fixes:

• Fixed a bug where scale_z_continuous() and scale_z_discrete() stored z scales in a package-level cache, causing plots to sometimes contaminate each other’s z-axis ranges. Now, the z scale is stored directly in the plot being built, preventing cross-contamination.
• geom_hull_3d()’s "alpha" method got some bug fixes related to face orientation and the radius parameter.

ggcube 0.2.0

• The new orbit_3d() function builds HTML widgets that let you interactively rotate ggcube plots.
• Plotmath is now supported in axis text and titles; e.g., xlab(expression(italic(alpha[1]))) now behaves as expected.
• Fixed several bugs, including issues with element_rect(), guide_legend_3d(), and camera-anchored lighting.

ggcube 0.1.0

• Initial CRAN submission.
