Projection Types – Section 4.2.1

Projection Type

How to Interpret

How to Use

Orthographic

Projection

Think of the "viewing volume" as a box whose opposite sides are parallel, so the distance from the camera does not affect the size of surfaces in the plot.

Used to maintain the actual size of objects and the angle between objects.

This works well for data plots. Real-world objects look unnatural.

Perspective

Projection

The "viewing volume" is the projection of a pyramid where the apex has been cut off parallel to the base. Objects farther from the camera appear smaller.

Used to create more "realistic" views of objects. This works best for real-world objects. Data plots may look distorted.
