Presently in Mathematica the same ParametricPlot3D command contains
options of 1 - and 2 - parametered manifolds to be embedded into 3
- space . There is perhaps a need felt in depicting
generalized spaces, putting n-D surfaces into m-D space where
special m=2, 3 ( R^2 and R^3) space could be fully shown.The command
ParametricPlot3D could be renamed ParametricPlot13 and
ParametricPlot23.
While attempting to generalize, it is noted that there are no direct
commands to address the options ParametricPlot22 and
ParametricPlot33. (n = m =2 and 3 respy.)
For example, ParametricPlot22[{ u + v, u v}, {u, -1, 1}, {v, -1,
1}] is not directly available but can be realized as a subset
command
after setting z = 0 choosing a remote z - ViewPoint in orthogonal
projection etc. in:
ParametricPlot3D[{ u + v, u*v, 0}, {u, -1, 1}, {v, -1, 1}, ViewPoint -> {0,
0, 50}, Shading -> False]
Likewise a command may be enabled as:
ParametricPlot33[{ u + w, u*v, Sin[ v + w] }, {u, -1, 1}, {v, -1, 1},
{w, -1, 1} ] for a 3-parameter manifold into 3-space.
