In 3D computer graphics, a wire-frame model (also spelled wireframe model) is a visual representation of a three-dimensional (3D) physical object. It is based on a polygon mesh or a volumetric mesh, created by specifying each edge of the physical object where two mathematically continuous smooth surfaces meet, or by connecting an object's constituent vertices using (straight) lines or curves.
Note that with the cube (see image) the perimeter of the resulting 2D drawing is a perfect regular hexagon: all the black lines have equal length and all the cube's faces are the same area. Isometric graph paper can be placed under a normal piece of drawing paper to help achieve the effect without calculation.
Reverse perspective, also called inverse perspective, [1] inverted perspective, [2] divergent perspective, [3] [4] or Byzantine perspective, [5] is a form of perspective drawing where the objects depicted in a scene are placed between the projective point and the viewing plane.
The lower left image shows a scene with a viewpoint marked with a black dot. The upper image shows the net of the cube mapping as seen from that viewpoint, and the lower right image shows the cube superimposed on the original scene. In computer graphics, cube mapping is a method of environment mapping that uses the six faces of a cube as the ...

Bryce, also often referred to colloquially as Bryce3D, is a 3D modeling, rendering and animation program specializing in fractal landscapes. [3] The name is taken from Bryce Canyon —a rugged region with many of the same landscapes that were first simulated with the software.
The impossible cube or irrational cube is an impossible object invented by M.C. Escher for his print Belvedere. It is a two-dimensional figure that superficially resembles a perspective drawing of a three-dimensional cube , with its features drawn inconsistently from the way they would appear in an actual cube.
A texture map [5] [6] is an image applied (mapped) to the surface of a shape or polygon. [7] This may be a bitmap image or a procedural texture.They may be stored in common image file formats, referenced by 3D model formats or material definitions, and assembled into resource bundles.
