The SVL vector & matrix package, version 1.5.
SVL provides 2-, 3- and 4-vector and matrix types, as well as
arbitrarily-sized vectors and matrices, and various useful functions
and arithmetic operators.
SVL is free for commercial and non-commercial use; see the LICENSE file
for redistribution conditions. (These apply only to the source code.
Binaries may be freely redistributed, no strings attached.)

History
Briefly: SVL, and its more complex cousin, VL, have their roots in
an attempt replace the various (inevitably heavily-macroized)
vector/matrix packages used by the members of the CMU graphics group
with a single C++ one, so that people could share code more easily.
SVL makes heavy use of inlines to achieve performance equal to that
of the C macros and functions it replaced.
To Make
Running 'make' with no arguments will list possible architectures to
compile for. The makefiles should work with most makes that have the
include directive, but try using gmake if something goes wrong.
If your architecture is not listed, copy and then modify the config file
in the makefiles directory that's closest to what you need.
To install, set the DEST variable appropriately and 'make install'.
DEST defaults to /usr/local.
E.g., to install into /usr on a linux machine:
make DEST=/usr linux install
from this directory.
To Use
#include svl/SVL.h, and link with -lsvl. To use in debug mode, add the
switch "-DVL_DEBUG" to your compile line, and link with -lsvl.dbg. See
the documentation for more information.

Changes
1.4 Fixed problem with SVLgl.h -- had some wrappers for OpenGL calls that
don't actually exist(!)
Fixed bad memory problem with Mat::SetSize
Makefile for OSX, split sunos/solaris
1.3.2 Fixed minor MSVC warnings
Added windows packaging
1.3.1 Sunday 11/03/01
Reordered initializers, eliminated signed/unsigned comparisons
Fixed make clean problem
Irix CC is warning that 'Mat2::*' is being called before its inline
definition, but appears to be on crack as the inline '*' is
defined before the xform() that calls it.
Fixed afs-lib dependency for afs build
1.3 Sunday 11/03/01
Split off from VL 1.3. All VL-dependent code and type
parameterization macros removed to make code more understandable.
Fix for the C++ "standard" no longer allowing stack temporaries to
be passes as non-const refs. (Fixing this for VL requires more
significant changes, so it's proved easier to fork SVL at this
point for the sake of simplicity.)
Renamed files, general cleanups.
Added ">>" operators for Vec and Mat.
Disallowed resize of a vector reference. (This caused more bugs
than it was worth.)
Removed all asserts checking that the return value of 'new' is
not zero. The C++ "standard" has been changed so that new
instead throws an exception in this situation.
Added option to use memcpy for general vector copies: VL_USE_MEMCPY.
It seems that nowadays, on Intel processors at least, using
memcpy is faster than loops for most cases. See note in Vec.cc.
Changed the packaging to match the current vl/gcl scheme.
Updated afs-setup rule to ensure SVLConfig.h winds up in the
architecture-dependent lib directory.
1.2 Release to match VL 1.2.
1.1.3 Fixed some windows compile issues under VC++.
1.1.2 Added comments about the Real, Vec, etc. types to VL.h
1.1.1 Fixed problem with += operators and gcc under linux.
1.1 Added oprod operator, irix n32 CC support, changed makefiles & afs
support, eliminated most g++ warnings.
