Projection methods in graphics When the projectors (lines of sight) are parallel to each other but strike the plane of projection at an angle other than 90°, what is this type of pictorial projection called?

Introduction / Context:
Pictorial projection methods help visualize 3D objects on 2D media. Understanding whether projectors are parallel or converge, and how they meet the projection plane, distinguishes isometric, oblique, and perspective views.

Given Data / Assumptions:

• Projectors are parallel to each other (not converging at a station point).
• The angle between projectors and the projection plane is not 90°.
• We are describing a pictorial method, not orthographic multiview.

Concept / Approach:
Oblique projection uses parallel projectors that intersect the plane at an oblique angle. The front face is shown in true shape; receding axes are drawn at a chosen angle (commonly 30°, 45°) with an optional scale (cabinet/cavalier).

Step-by-Step Solution:

Verification / Alternative check:
Compare with isometric: projectors are perpendicular to plane (orthographic) but object is oriented so edges are equally foreshortened. That differs from oblique where the front face is undistorted and receding axes are angled.

Why Other Options Are Wrong:

• Perpendicular projection: Refers to orthographic, not the described oblique condition.
• Aesthetic/Angular: Nonstandard labels in technical graphics.

Common Pitfalls:
Using full-scale receding axes (cavalier) can exaggerate depth; cabinet (half scale) often looks more realistic.

Final Answer:
Oblique projection
