The Colourful Release

Summary

This release brings you:

• Over 100 new, beautiful, perceptually uniform colourmaps from Crameri and CET (also incorporating code from William Lenthe). The screenshots come from the example programs colourmaps_crameri, hsvwheel, colourmaps_cet and colourmap_browser.

• The ability to read and visualize spherical HEALPix grids (images from healpixviewer)

• Some refactoring of core maths classes (including Scale->scale; Quaternion->quaternion; TransformMatrix->mat44)
• Improvements in OpenGL context handling along with the ability to coordinate access to the context via a mutex (thanks @connagh-opteran)
• It also introduces some changes and new features in morph::Grid and GridVisual (thanks @blenk13 and @fabien-colonnier). The screenshot is from the example program grid_border.

• The option to use a signed index in vvec (where v.at_signed(-1) accesses the last element in the vvec)
• Graph axis labelling improvements (especially re-sizing the font for axis tick labels)
• Complex number handling in morph::range and morph::scale
