Usage

Including all the files as headfiles.

using namespace aya;

Basic Target

A lite utility linear algebra math library including basic functionalities of Matrix, Vector , Quaternion and some simple math algorithms.

As a component of AyaRay developed by Chang Yu.

Design Mode

• Fully support SIMD hardware acceleration (as a default mode)., you can use AYA_USE_SIMD macro in MathUtility.h to switch on/off.

• Adapt the architecture of pbrt-v3, achieve all the functions existed in pbrt-v3's gemetry.h in the same interfaces.

• Avoid the tedious codes of building different base classes of Vector/Point/Normal，which means unnecessary overloading, copying and conversion. Abstract all this classes into BaseVector3, all subclasses inherit from it (including illegal methods that demand programmer to avoid it)

• Considering the encode demand of SIMD and the confusing error LNK2019 caused by c++ template use. Only support float type currently.

• All functions are implemented as class member functions, following object-oriented thinking to ensure that namespaces are not contaminated. (Some functions need to use like Matrix3x3().getIdentity())

• Only support Windows(x86) platform currently.

• Guarantee multi-thread safety.

• Follow Google code style
