A Cartesian coordinate system in two dimensions (also called a rectangular coordinate system or an orthogonal coordinate system[8]) is defined by an ordered pair of perpendicular lines (axes), a single unit of length for both axes, and an orientation for each axis.
19 Ιουν 2017 · THREEJS: Matrix from Z-Up Coordinate System to Y-Up Coordinate System. This method just change the object or mesh y and z vertices but if I rotate it around y axis it rotates around the traditional y axis.
The second specified axis defines the plane between the corresponding first and second axes of the new axis system. i.e., if the z-axis is specified by Line.2, then the xz plane is defined by the plane between vectors along Line.1 and Line.2.
2 Σεπ 2024 · The horizontal number line is called the x -axis, and the vertical number line is called the y -axis. These two number lines define a flat surface called a plane, and each point on this plane is associated with an ordered pair of real numbers (x, y).

Cartesian coordinates of three-dimensional space. In three-dimensional space, the Cartesian coordinate system is based on three mutually perpendicular coordinate axes: the x x -axis, the y y -axis, and the z z -axis, illustrated below. The three axes intersect at the point called the origin.
A three-dimensional coordinate system is created by adding a new axis, called the z-axis, to the familiar xy-coordinate system. The new z -axis is inserted through the origin perpendicular to the x - and y -axes ( Figure 13.25 ).
