Trajec3D Version 220.127.116.11 available for download
Trajec3D Version 18.104.22.168 extends the expiration date to 1 January 2021 and adds two new options:
Check "Bottom panel => Environment => Body rotation => Randomise" to change the starting orientation of every fall body. When checked, the value in "Body rotation" is ignored and the fall body orientation randomly changed along all three axes.
The number of fall bodies that can simultaneously be released with "Left toolbar => Select multiple bodies for simultaneous release" was increased to a total of 100 to allow for the release of more simultaneous fall bodies.
