Version 1.6.1 of AstroGrav has the following new and improved features.
Creating New Families
Version 1.6.1 of AstroGrav includes a significant improvement to the Edit / Add Family... command. In previous versions, the numbers initially displayed in the dialog were always the default ones from the first of the Quick Setup options. This has been changed so that the numbers initially displayed in the dialog are now a copy of the ones that you last accepted. This makes the process of experimenting with the creation of new families much easier because you can now repeat the following sequence until you achieve the desired affect.
There is also a correction to a bug that caused the Quick Setup options of 3D Collapsing Cloud and 2D Confocal Hyperbolae to sometimes work incorrectly when adding the family to an object that already had lesser objects orbiting it.
Version 1.6.1 of AstroGrav includes a correction to two faults that caused object collisions to sometimes not work correctly. While collisions worked correctly in most situations, the volume of the compound object would occasionally be greater than the sum of the volumes of the constituent objects, and occasionally collisions would get missed so that two objects would pass through each other. These faults have now been corrected, so that collisions work correctly in all circumstances.
Display Of Numbers
Version 1.6.1 of AstroGrav includes an improvement to the way that numbers are displayed. In previous versions, simple numbers such as 1.2 were sometimes displayed as (for example) 1.199999999999998 or 1.200000000000002. This has now been corrected, so that numbers always display correctly.
Version 1.6.1 of AstroGrav also has many other minor improvements and bug fixes, including the following.
