Projecting Points and Shapes

Projecting points onto a plane involves rays passing through the points and intersecting the plane. These intersections are called projections. Projecting a shape involves projecting its vertices.

Projection Systems

There are two main systems of projection:

Perspective Projection

When the rays originate from a single point, the system is called perspective projection. The resulting shape is proportionally smaller or larger.

Parallel Projection

When the rays are parallel, the system is called parallel projection. The resulting shape is congruent (same shape and size). There are two variations:

1. Oblique Projection: The rays are oblique to the projection plane.

2. Orthographic Projection: The rays are perpendicular to the projection

Focal Length: Understanding Wide-Angle, Medium, and Telephoto Lenses

1. Wide-Angle Lenses

Wide-angle lenses capture a wider field of view, but they can distort straight lines near the edges of the frame, making them appear curved outward. Additionally, wide-angle lenses exaggerate depth, making objects in the foreground appear larger and those in the distance appear farther away. As a result, when figures move toward or away from the camera, a wide-angle lens makes them seem to cover ground more rapidly.

2. Medium Lenses

Medium lenses, typically around 50mm in length, aim to avoid noticeable perspective distortion. With a medium lens, horizontal and vertical lines are rendered as straight and perpendicular.

3. Telephoto Lenses

Telephoto lenses have... Continue reading "Understanding Focal Length: Wide-Angle, Medium, and Telephoto Lenses" »
