PICTORIAL DRAWING: PARALLEL AND PERSPECTIVE PROJECTION

By F MOTUFAGA

Pictorial drawing in this volume includes parallel projection and perspective projection concepts.In Parallel projection:A complete guide for axonometric projection i.e. by auxiliary projection and by the applications of Pohlke' theorem:* The concepts of axonometric projection i.e. isometric, dimetric and trimetric:* How to auxiliary project a drawing in dimetric or trimetric projection.* The different tilt axis planes in axonometric projection that will result in either a dimetric or trimetric projection* The axonometric tilt angles for isometric, dimetric and trimetric projections e.g. the isometric tilt angle of 35.3?* The methods of constructing axonometric scales i.e. by the auxiliary projection method and by the application of Pohlke's theorem method * Dimetric and trimetric projection examples with their constructed scales* A comparison of the three axonometric scales* The first and second tilt angles in auxiliary projections* * The construction of the first and second tilt angles for a dimetric or a trimetric projection* * Pohlke's theorem : A lines on planes approach * * Proof of Pohlke's theorem by the auxiliary projection method* Isometric projection drawings from a true diagonal* The isometric circle and sphere projected and compared to a circle* Adjusting the isometric drawing methods for a circle to accommodate isometric projection* The comparison of constructing isometric circles using the ordinates method and the 8 points method with respect to isometric drawing or projection.* An analysis of the approximate 4 arcs method for isometric* Drawing a sphere in isometric.* The concepts of oblique projection:* The comparison of constructing oblique circles with respect to cavalier or cabinet oblique.* The 8 points method for oblique drawing as compared to the ordinates method for oblique drawing* The ordinates method for cabinet oblique.* Views of planometric drawings in 2 and 3 dimensions.In Perspective projection:* The concepts of one and two point perspective i.e. Parallel and Angular perspective (1PP and 2PP)* The concepts of perspective drawing are discussed from a path or trajectory approach. * The perspective range* The receding direction* The concepts of the vanishing points and the horizon* The planes in perspective:* Vertical and horizontal planes* Picture plane* Eye level plane* Line of Sight plane* SP to VP plane* Methods of locating points in one and two point perspective* Intersecting trajectories* Angular and parallel perspective examples and exercises
