Time that an event takes to happen after all the occurring conditions are met.
Corner of a bounding box defined as 2 or 3 space-separated values in a string, e.g.:
5.5 6
1 5 10.2
Dimensions of a bounding box defined as 2 or 3 space-separated values in a string, e.g.:
5.5 6
1 5 10.2
Rotation defined as string formatted as a space-separated vector of size 2 or 3, representing Euler angles in radians defined according to the YXZ convention, e.g.:
0 0
0 0 0
3.141 0 0
Point defined as 2 or 3 space-separated values in a string, e.g.:
5.5 6
1 5 10.2
Rotation defined as string formatted as a space-separated vector of size 4, representing a quaternion (w, x, y, z), e.g.:
1 0 0 0
0 0 0 1
0.5 0.5 0.5 -0.5
Rotation defined as string formatted as a 2 by 2 or 3 by 3 matrix. Each row of the matrix is separated by a semi-colon. Elements on the same row are space-separated values, e.g.:
1 0; 0 1
1 0 0 ; 0 1 0; 0 0 1
Rotation of a 3D Cartesian transformation defined as string formatted as a 2 by 2 or 3 by 3 matrix. Each row of the matrix is separated by a semi-colon. Elements on the same row are space-separated values, e.g.:
1 0 0 ; 0 1 0; 0 0 1
Scale of a Cartesian transformation defined as 1 or 2 or 3 space-separated values in a string, e.g.:
2
1 3
1 1.5 2
In case of only one value, then the transformation is uniform along all directions.
Translation of a 3D Cartesian transformation defined as 2 or 3 space-separated values in a string, e.g.:
5 10
1 1.5 2
Definition of a time quantity that is directly or indirectly related to probability distributions.
The unit of measurement can be explicitly defined, otherwise the default value defined for time measures applies.
If an actual value is defined without specifying a probability distribution where it is sampled from, then the value must be intended as deterministic.
