The discrete equations originate from a finite element discretization of the characteristic-bias system and are integrated in time within a compact block tridiagonal matrix statement by way of an implicit non-linearly stable Runge-Kutta algorithm for stiff systems. As documented by several comp...
Verge3D 使用intrinsicTait-Bryan angles(Yaw、Pitch、Roll)。 这意味着旋转是在坐标系下进行的。也就是说,对于“XYZ”顺序,首先是围绕local-X轴旋转(与world- x轴相同), 然后是local-Y(现在可能与world y轴不同),然后是local-Z(可能与world z轴不同)。
