"People who try to explain pictures are usually barking up the wrong tree." . . . Picasso¹

Not withstanding above quote from Picasso, we will Study, Understand, Practice, Integrate, and hopefully Master, the following kinds of drawings and terms (listed in random order):

Projection, Orthographic, Objective/Pictorial/Optical/Gravitational/Aerial/Masked Space, Paraline, 3-D, Axonometric, Isometric, Dimetric, Trimetric, Plane Oblique, Elevation Oblique, Section Oblique, Reflected Ceiling Plan, Sectional Perspective, Freehand, Constructed, Mathematical, Photographic, 1-Point, Interior, Exterior, 2-Point, 30/60 Degree system, 45 Degree System, 45 Degree Point, 3-Point, any number of Points, Zenith, Nadir, Eye-level, Aerial, Birds-eye, Bugs-eye, Worms-eye, Fish-eye, Barrel Distortion, Pin-cushion Distortion, Skew Distortion, Trapezoid Distortion, Lofting, Mapping (texture and/or image), Mirror, Morphing, Non-print Leads, Porché, Tweaking, Tweening, Twiddling, Vector Image, Conventional, Measuring Point, Object, Picture Plane, Clipping Plane, Station Point, Eye-level/Horizon Line, Field of Vision, Vanishing Points, 45 Degree V.P.s, Visual Ray, Ground Plane, Station Point, Sight Point, Eye Location, Camera Location, Target, Center of Interest, Center of Vision, Impossible Objects, Collaged, Computerized, Glide, Stereoscopic, 360 Degree, Reverse, Anamorphic, Atmospheric, Luminous, Stage, Spiderman, Layered, Filter Overlay, Multi-Scaled, Rescale, Isovists, Series, Sequential, Walk-thru, Fly-by, Animated, Kinematics, Pan, Panorama, Cyclorama, Diorama, Storyboard, Wireframe, Hiddenline, Shaded, Cast shadowed, Conceptual Diagram, Full-bleed, Image Sampling, Choisy, Daguere, Arnheim, Lockhard, Ching, Yeh, Forseth, Leach, Goldman, Kliment, Mitchell, Norman, Porter, Stuart, Uddin, and any other kind² of Perspective Methodology you can think of, in order that you may Develop the Confidence in your own Knowledge and your own Eye-Judgment, and Never Fear the Little Word, "perspective", again.

And what I don't know after 50-years you will show me, right? I believe I am still able to learn! Are you? It's what keeps me going and interested in life.

For Example:

Last week, I finally "discovered" the problem with the way computer programs draw perspectives. They do it in a manner different than what we, as mere humans bound to our Earth Mother, can understand. Computers operate, calculate, and draw in a vacuum of outer space, zero-gravity, xyz coordinates, mathematically abstract environment. It's not "incorrect", but it's not the way we perceive, i.e.: sense, process, understand, navigate, and otherwise use information about our environment. We operate in "gravitational space".

Computer Drawing

vs. drawing "corrected" for human "consumption"³

² These terms are not all "perspectives" but are often heard in association with the discussion of perspective, computer graphics, and/or other ways of seeing.

³ From my own studies of drawing the Architecture Courtyard on window in south end of 4th level central hall, GOL. Originally done as demonstration for Vis.Com. II class this summer and continued after session was over into 4th level hall of Sutton on wall opposite my office SUT 4.112. Further analysis may be seen there.
