opengl 中的 gml 函数库四元素转为旋转矩阵（亲测可用）

        int main()
        {
            glm::mat4 MyMatrix=glm::mat4();

            myQuat=glm::quat(0.707107,0.707107,0.00,0.000);
            glm::mat4 RotationMatrix = glm::mat4_cast(myQuat);
            

            for(int i=0;i<4;++i)
            {
                for(int j=0;j<4;++j)
