Lesson Closure A coordinate system is used by engineers in all designs. The coordinate system is used to specify dimensions for products. When an engineer designs a part, s/he specifies where each point on the part is located using a Computer Aided Design (CAD) program.

Coordinate planes can be a useful tool for architects. Blueprints are usually laid out on a coordinate grid to help identify angles and side lengths. For this interactive, you will use the distance between points on a coordinate plane to calculate the perimeter of a polygon.

The coordinate plane can be used to plot points and graph lines. This system allows us to describe algebraic relationships in a visual sense, and also helps us create and interpret algebraic concepts.

The Cartesian coordinate plane of x and y works well with many simple situations in real life. In other settings, your smartphone screen also uses a Cartesian coordinate plane to track where you’re touching on the screen, and PDF files or images have a plane to specify locations in the same way.

XYZ

When referring to a three-dimensional plane, a z-axis refers to the depth of a three-dimensional object. In the illustration, the z-axis plane goes front to back, and intersects with the y-axis and x-axis at the origin.

Definition: (1) Line perpendicular to the plane containing the X and Y axes, which is conventionally taken as the plane facing the viewer. * Usually used to measure a third dimension or variable.

Why is the z-axis important to videographers? The z-axis is important to videographers because it creates a three-dimensional setting on a two-dimensional screen. Manipulations of the z-axis can alter the viewer’s perception of the video and are utilized by videographers to portray a certain message or tone.

When performing precision shaft alignment on horizontal rotating machinery, the Z axis refers to the rotational axis or rotational centerlines. The Y axis refers to vertical position (perpendicular to the base) and the X axis refers to the horizontal position (parallel to the base).

AXIS OF ACTION: In CONTINUITY EDITING, the imaginary line that passes from side to side through the main actors, defining the spatial relations of the scene. The camera is not supposed to cross the axis at a cut and reverse the spatial relations.

Plain and simple, the reason for the 180 degree shutter angle rule is to have proper motion blur. The rule states what your shutter speed should be set to relative to the frame rate of your camera. Just double your frame rate. If you’re shooting at 30 fps, your shutter speed should be set to 60.

• The thing about the 180-degree rule is that it’s pretty simple in theory: draw an imaginary line down the center of the action and then only shoot from one side.

A good rule of thumb to go by is to ensure that the denominator of your utilized shutter speed (ie: 1/48, 1/96, 1/44, etc) should be doubled what your frame rate is. So, if you’re shooting at 60fps, your shutter speed should be 1/120 and a 1/240 shutter speed for 120fps — so on and so forth.
