Boost QVM has been updated. Note, this library has not been reviewed yet and it is not part of Boost. Boost QVM provides a set of generic functions for working with quaternions, and vector and matrix types of static size. All operations use a type-traits system, which enables types from other vector/matrix libraries to be integrated in a common type-safe interface. The current source code and documentation is available at http://www.revergestudios.com/boost-qvm. It contains minor bug fixes, and the following new features: - view proxies that negate matrix rows and columns (negr/negc) - view proxies that swap two rows or columns in a matrix (swapr/swapc) - functions for indexing at run-time of any vector or matrix object of arbitrary size. Comments and bug reports are appreciated. Thanks! Emil Dotchevski Reverge Studios, Inc. http://www.revergestudios.com/reblog/index.php?n=ReCode
