Perspective Drawing Diagram: Cross and Wedge Projection with Vanishing Points #3027102 (License: Personal Use)

This black-and-white architectural drafting diagram illustrates the application of linear perspective to render a vertical cross and an inclined wedge in three dimensions. Key elements include the horizon line (HL), principal point (P), multiple vanishing points (VP¹-VP⁴), and construction lines indicating sightlines, depth planes, and foreshortening. The labeled points (a-w) and angles (30°, 40°, 55°) denote precise spatial relationships essential for accurate orthographic-to-perspective conversion.

Used in architecture, art education, and technical drawing resources to teach perspective theory; ideal for pages on Renaissance drawing techniques, CAD visualization fundamentals, or historical drafting methods where users seek instructional diagrams for constructing 3D forms on 2D surfaces.
