soo

soo is a simple 3D math library that provides essential features for game programming.

Features

• 3D Vector

  soo::Vector3<double> vec1{1.0, 2.0, 3.0};
  soo::Vector3d vec2{3.0, 4.0, 5.0}; // Vector3d is the type alias for Vector3<double>.
   
  double dotProduct = vec1.dot(vec2);
  soo::Vector3d crossProduct = vec1.cross(vec2);
   
  vec1.normalize();

• Arbitrary-size Matrix

  // 2 X 3 Matrix
  soo::Matrix<double, 2, 3> mat1{
      {1, 2, 3},
      {4, 5, 6}
  };
   
  soo::Matrix<double, 3, 2> mat2{
      {7, 8},
      {9, 10},
      {11, 12}
  };
   
  auto mult = mat1 * mat2; // mult is a 2 X 2 matrix.
   
  auto transposed = mat1.transpose(); // transposed is a 3 X 2 matrix.
   
  // Vector multiplication is only available in 4 X 4 matrix (Affine transformation)
  soo::Vector3d vec1{1, 2, 3};
  soo::Matrix4d mat3{ // Matrix4d is the type alias for Matrix<double, 4, 4>.
      {0, -1, 0, 10},
      {1, 0, 0, 20},
      {0, 0, 1, 30},
      {0, 0, 0, 1}
  };
   
  auto transformed = mat3 * vec1;

Usage

1. Copy include/soo directory to your project, then add its path to the include path.
2. include header as below:
   

   #include "soo/soo.h"

Refer documentation for the implementation details.
