弧度或度

当我从欧拉角创建旋转矩阵时，我是否应该将度（欧拉角）转换为弧度，然后计算 OpenGL 的旋转矩阵？但是我应该如何处理四元数？我应该执行以下操作吗：

void setQuaternionsFromEuler(float bank, float heading, float attitude)
{
   float DegreeToRadian = 3.14f/180.0f;
   double c1 = cos(heading/2*DegreeToRadian);
   double c2 = cos(attitude/2*DegreeToRadian);
   //...
   double s3 = sin(bank/2*DegreeToRadian);
   this.w = c1*c2*c3 - s1*s2*s3;
   //...
}

和

void setMatrixFromEuler(float x, float y, float z)
{
   float DegreeToRadian = 3.14f/180.0f;
   x *= DegreeToRadian;
   y *= DegreeToRadian;
   //...
}

要不？
