Though normal projection screens are commonly used, some visual artists are beginning to create custom made, 3D installations to project onto.
2.
If so, once you find the normal projection of the point onto the plane, finding the point on the opposite side is almost trivial.
3.
If point 0 is the original, point 1 is the normal projection onto the plane, and point 2 is the reflected point behind the plane, find point 2 as follows:
4.
This parameter is then used to find the ( x, y, z ) coords of that normal projection, and the distance from there to the test point can then be determined.
5.
:If you need to stick with the b-spline, then perhaps rather than doing a normal projection, the best method would be to find the closest point on the b-spline to each point.
6.
"The normal projections that we make with respect to what the economy will be doing in the longer run requires that we have a very firm judgment on what the long-term productivity growth is, " he said.
7.
:: 3 ) The determination of the distance of a test point from the ray is done by first finding the T parameter ( length along the ray from the origin ) of the normal projection of the test point onto the ray.
8.
Here, again, a b-spline could complicate things, as you don't necessarily get a single normal projection for each point, while a truly elliptical curve would only allow one normal projection ( unless projecting from the center point, or if you count the projection through the center point to the far side of the ellipse ).
