SVD and other matrix decompositions on 3x3 matrices written in GLSL
// This is a GLSL implementation of
// "Computing the Singular Value Decomposition of 3 x 3 matrices with
// minimal branching and elementary floating point operations"
// by Aleka McAdams et.al.
// http://pages.cs.wisc.edu/~sifakis/papers/SVD_TR1690.pdf
// This should also work on the CPU using glm
// Then you probably should use glm::quat instead of vec4
// and mat3_cast to convert to mat3.

Orthodox C++

Orthodox C++

What is Orthodox C++?

Orthodox C++ (sometimes referred as C+) is minimal subset of C++ that improves C, but avoids all unnecessary things from so called Modern C++. It's exactly opposite of what Modern C++ suppose to be.

Why not Modern C++?
