Project:The Open Toolkit library
Version:1.0-beta-2
Component:Code
Category:bug report
Priority:normal

Description

Current implementation:
inv(Q) * V * Q

Standard convention:
Q * V * inv(Q)

I'm using the latter so not able to use OpenTK function.

Are you using trunk or the 1.0 branch?

Just to make sure we are on the same wavelength:

I haven't backported those fixes to trunk yet.

Oh, thanks for the explanation.
I verified the routine works correctly (using 1.0 branch).
Thanks!
