z-Axis. The axis in three-dimensional Cartesian coordinates which is usually oriented vertically. Cylindrical coordinates are defined such that the -axis is the axis about which the azimuthal coordinate is measured.
Also asked, what do you call the Z axis?
For 3D diagrams, the names "abscissa" and "ordinate" are rarely used for x and y, respectively. When they are, the z-coordinate is sometimes called the applicate. The words abscissa, ordinate and applicate are sometimes used to refer to coordinate axes rather than the coordinate values.
Which direction is the Z axis?
In both coordinate systems, the positive x-axis points to the right, and the positive y-axis points up. You can remember which direction the positive z-axis points by pointing the fingers of either your left or right hand in the positive x-direction and curling them into the positive y-direction.
What is the z axis in film?
Z-axis refers to the axis that runs from the foreground-to-the-background or background- to-the-foreground in the frame. The Z-axis is what gives the audience its sense of 3-D space or depth-of-field. Here's how screen direction expressed six different ideas. Film Element: Screen Direction. 1.
