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...

Homogeneous transformation matrix, specified by a 4-by-4-by-n array of n homogeneous transformation matrices. When using the transformation matrix, premultiply it with the coordinates to be rotated (as opposed to postmultiplying). Example: [0 0 1 0; 0 1 0 0; -1 0 0 0; 0 0 0 1] ...
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)。

What Are Euler Angles? Euler angles are a method of determining the rotation of a body in a given coordinate frame. They can be defined as three rotations relative to the three major axes. Euler angles are most commonly represented as phi for x-axis rotation, theta for y-axis rotation and...
