应用方式1

glm::dvec3 aveVec3;
glm::dmat3 covarMat3;
OBBbox::compute3DCovariance(vertexList, aveVec3, covarMat3);
std::cout << "aveVec3:  " << std::endl;
printGLM(aveVec3);
std::cout << "covarMat3:  " << std::endl;
printGLM(covarMat3);

应用方式2

glm::dvec3 aveVec3;
glm::dmat3 covarMat3;
OBBbox::compute3DCovariance(vertexList, aveVec3, covarMat3);
std::cout << "aveVec3:  " << std::endl << glm::io::precision(20) << glm::io::width(25) << aveVec3 << std::endl;
std::cout << "covarMat3:  " << std::endl  << glm::io::precision(20) << glm::io::width(25) << covarMat3 << std::endl;

----------------

应用方式3

glm::dvec3 aveVec3;
glm::dmat3 covarMat3;
OBBbox::compute3DCovariance(vertexList, aveVec3, covarMat3);
std::cout << "aveVec3:  " << glm::to_string(aveVec3) << std::endl;
std::cout << "covarMat3:  " << glm::to_string(covarMat3) << std::endl;
