point of intersection: A point that makes easier the layout, toolpath programming, or inspection of the part. It is the intersection point of lines that may not meet on the finished part, such as the tangent lines of a curve or the theoretical sharp corner (TSC) that edge-breaking and deburring will remove. See also SC, TSC, and AC. P.F.
There will be an intersection if 0 ≤ t ≤ 1 and 0 ≤ u ≤ 1. The intersection point falls within the first line segment if 0 ≤ t ≤ 1, and it falls within the second line segment if 0 ≤ u ≤ 1. These inequalities can be tested without the need for division, allowing rapid determination of the existence of any line segment ...
It can be used for line or line-segment clipping against a rectangular window, as well as against a convex polygon. The algorithm is based on classifying a vertex of the clipping window against a half-space given by a line p: ax + by + c = 0. The result of the classification determines the edges intersected by the line p. The algorithm is ...
The three possible plane-line relationships in three dimensions. (Shown in each case is only a portion of the plane, which extends infinitely far.) In analytic geometry, the intersection of a line and a plane in three-dimensional space can be the empty set, a point, or a line. It is the entire line if that line is embedded in the plane, and is ...
Alternatively, a line can be described as the intersection of two planes. Let L be a line contained in distinct planes a and b with homogeneous coefficients (a 0 : a 1 : a 2 : a 3) and (b 0 : b 1 : b 2 : b 3), respectively. (The first plane equation is =, for example.)
We break it down for you here. Start with a cold pan. There’s a good chance you learned to cook scrambled eggs by starting them in a hot skillet, but Flay recommends adding ingredients to a cold ...
News of the deal arrives with the Lions in line for the No. 1 seed in the NFC playoffs. Detroit is 11-1 following a Thanksgiving win over the Chicago Bears. Adams, 29, most recently played for the ...
Players would sweep up the bleachers after high school games ended, tape the college 3-point line onto the court and then practice until they were too heavy-legged and bleary-eyed to go any later.
