The tetrahedron-first orthographic projection of the runcinated 5-cell into 3-dimensional space has a cuboctahedral envelope.
22.
For directional light ( e . g ., that from the Sun ), an orthographic projection should be used.
23.
"' Orthographic projection "'is a means of representing a three-dimensional object in two dimensions.
24.
More specifically a plan view is an orthographic projection looking down on the object, such as in a floor plan.
25.
Orthographic projections have the property that all parallel lines in 3-space will remain parallel in the 2-D representation.
26.
Orthographic projections are a small set of transforms often used to show profile, detail or precise measurements of a three dimensional object.
27.
The square-face-first orthographic projection of the tetrahedral prism into 3D space has a cubical envelope ( see diagram ).
28.
The pentagonal-prism-first orthographic projection of the dodecahedral prism into 3D space has a decagonal envelope ( see diagram ).
29.
Orthographic projection is distinguished by parallel projectors emanating from all points of the imaged object and which intersect of projection at right angles.
30.
It also gave the names we now use to stereographic projection and orthographic projection, although the projections themselves were likely known to Hipparchus.
