Visualizing with CAD: An Auto CAD Exploration of Geometric by Daniela Bertol

By Daniela Bertol

I spent the 1st twenty six years of my lifestyles in Rome. I used to move for ice cream to a favored position close to the Pantheon and that i remem­ ber the thrill I felt, past the chocolate and whipped cream, whilst I entered this historic Roman temple. After observing the "shower" of sunshine coming from the round commencing on the heart of the dome, as robust as a focus, I have in mind being attracted nearly hypnotically to where less than the outlet. I consider counting the coffers carving the concave dome, com­ posed in 5 rows of round arrays, and will believe the ability and safety created through the concave area. I additionally bear in mind going each Sunday to Piazza San Pietro. This Baroque sq. is widely known for its colonnades, that have an oval form outlined through interlocking circles. for every of those circles there's a mark, positioned nearly at its heart, from which the 4 aligned rows of columns look as one. prior to getting into the church, nearly as part of a ritual, I needed to locate the mark within the pavement of the oval sq.. i used to be surprised through how the rows of columns may seem and disappear in accordance with my place in terms of the mark:.

In the same way that space can be viewed in terms of both container and extension, the perceptual field of space is articulated through a series of solids separated by voids. Often in architecture solid is defined as positive space and void as negative space; they are complementary to each other and one A FEW CONSIDERATIONS 7 1-3 ~ a. A famous example of figure-ground ambiguity. b. The ambiguity tends to disappear when one of the ambiguous elements is represented in perspective view. a b 8 VISUALIZING WITH CAD could not exist without the other.

Baroque architecture offers several examples of two-dimensional imagery used to add a theatrical dimension. These topics will be considered again in the next chapter, dealing with representation methods in CAD. CONTINUITY AND DISCRETENESS The geometrical and perceptual properties of space reveal another dichotomy defined by the concepts of "continuity" and "discreteness," which represent two mathematical descriptions of the world. This dualism goes beyond geometry. From intuitive observation, any form, natural or artificial, can be defined in these terms, at least at a A FEW CONSIDERATIONS 33 macroscopic level.

Visualization 1- t 9 Two different categories of images. a. Images representing twodimensional shapes. b. Images representing threedimensional shapes. The relation between physical space and its visual perception is of fundamental importance for every type of visual representation, or visualization. Essentially visualizations are composed of the spatial boundaries of a form in terms of figure-ground, which provide information about visual characteristics such as contours, lines, area of colors, gradients, and so forth.
