Hidden lines are particularly useful when viewing an object from an angle where the visible only lines do not have much information. In a computer drawing application the option may be referred to a wire frame with hidden edges. [6] The hidden edges would be dashed lines. A wire-frame image using hidden-line removal
The hidden-line algorithm uses n 2 exclusive read, exclusive write (EREW) PRAM processors. The EREW model is the PRAM variant closest to real machines. The hidden-line algorithm does O(n 2 log n) work, which is the upper bound for the best sequential algorithms used in practice. Cook, Dwork and Reischuk gave an Ω(log n) lower bound for finding ...

Type E lines indicate hidden outlines of internal features of an object. These are dotted lines. 2H pencil; Type F lines are Type E lines, except these are used for drawings in electrotechnology. 2H pencil; Type G lines are used for centre lines. These are dotted lines, but a long line of 10–20 mm, then a 1 mm gap, then a small line of 2 mm ...
Hidden-surface determination is a process by which surfaces that should not be visible to the user (for example, because they lie behind opaque objects such as walls) are prevented from being rendered. Despite advances in hardware capability, there is still a need for advanced rendering algorithms. The responsibility of a rendering engine is to ...
Though cutaway drawing are not dimensioned manufacturing blueprints, they are meticulously drawn by a handful of devoted artists who either had access to manufacturing details or deduced them by observing the visible evidence of the hidden skeleton (e.g. rivet lines, etc.). The goal of this drawings in studies can be to identify common design ...
A structural drawing, a type of engineering drawing, is a plan or set of plans and details for how a building or other structure will be built.Structural drawings are generally prepared by registered professional engineers, and based on information provided by architectural drawings.
Whiteprinting replaced the blueprint process for reproducing architectural and engineering drawings because the process was simpler and involved fewer toxic chemicals. A blue-line print is not permanent and will fade if exposed to light for weeks or months, but a drawing print that lasts only a few months is sufficient for many purposes.
