COMPSCIE 8

It provides a 3D image to help understand the shape of an object or to assist in interpreting a drawing.

• Pictorial drawing

• Electrical diagrams

• Electronics diagrams

• Orthographic projections

It is a pictorial representation of an object in which all three dimensions are drawn at full scale.

• Isometric drawings

• Oblique drawings

• Perspective drawings

• Schematic Diagrams

It produced an image of an object in three dimensions that is very similar to what the human eye sees.

• Pictorial drawings

• Oblique drawings

• Perspective Drawing

• Schematic Diagrams

This is probably the simplest method of producing a pictorial drawing because surfaces are directly in front of the viewer will look very similar to the front view in an orthogonal drawing.

• Pictorial drawings

• Oblique drawings

• Perspective drawings

• Schematic diagrams

This is obtained when the angle between oblique

projectors and the plane of projection is 45⁰ and the rear projections are true to size.

• Cavalier projection

• Cabinet projection

• orthographic projection

• isometric projection

An oblique projection where the length of the lines projecting backwards are halved.

• Cavalier projection

• Cabinet projection

• orthographic projection

• isometric projection

This type of perspective is often used when the subject is viewed directly from the front or rear.

• One-Point Perspective

• Two-Point Perspective

• Three-Point Perspective

• Zero-Point (Fish-eye) Perspective

• It involves two vanishing points on the horizon line, with sets of parallel lines converging towards each point used when the subject is viewed from an angle, showing two sides.

• One-Point Perspective

• Two-Point Perspective

• Three-Point Perspective

• Zero-Point (Fish-eye) Perspective

• Two are on the horizon line, and the third is either above or below the horizon, representing the vertical convergence of lines and is often used when looking up at tall objects or down at deep spaces.

• One-Point Perspective

• Two-Point Perspective

• Three-Point Perspective

• Zero-Point (Fish-eye) Perspective

• This is known as fish-eye perspective, there is no vanishing point. Instead, the distortion increases as you move away from the center of the composition. This is used for a distorted, wide-angle view, often seen in panoramic or immersive environments.

• One-Point Perspective

• Two-Point Perspective

• Three-Point Perspective

• Zero-Point (Fish-eye) Perspective
