Wolfram: View Point and Perspective
View Angle
use these to control position of the camera and orientation.
ViewVector is short for
ViewPoint and
ViewCenter
ViewProjection (Perspective)
ViewProjection -> "Perspective"ViewProjection -> "Orthographic"
by default it is "Perspective"
ViewProjection basically change ViewPoint's distance.
xcubes = Table[Cuboid[{x, y, z} - 0.2, {x, y, z} + 0.2], {x, -5, 5}, {y, -5, 5}, {z, -5, 5}]; { Graphics3D[xcubes, ViewPoint -> {1,1,1}, ViewProjection -> "Perspective"], Graphics3D[xcubes, ViewPoint -> {1,1,1}, ViewProjection -> "Orthographic"] }
ViewMatrix
ViewMatrix overrides all
SphericalRegion Bounding Box
This is useful when you don't want graphics to resize when you rotate it interactively.
SphericalRegion -> True
ParametricPlot3D[ {Cos[u]*(2 + Cos[v]), Sin[u]*(2 + Cos[v]), Sin[v]}, {u, 0, 5}, {v, 0, 5}, PlotStyle -> White, SphericalRegion -> True ]
