The result of the classification determines the edges intersected by the line p. The algorithm is simple, easy to implement and extensible to a convex window as well. The line or line segment p can be computed from points r 1, r 2 given in homogeneous coordinates directly using the cross product as p = r 1 × r 2 = (x 1, y 1, w 1) × (x 2, y 2 ...
Fitting of a noisy curve by an asymmetrical peak model, with an iterative process (Gauss–Newton algorithm with variable damping factor α).Curve fitting [1] [2] is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, [3] possibly subject to constraints.
A simple way to parallelize single-color line rasterization is to let multiple line-drawing algorithms draw offset pixels of a certain distance from each other. [2] Another method involves dividing the line into multiple sections of approximately equal length, which are then assigned to different processors for rasterization. The main problem ...
Line fitting is the process of constructing a straight line that has the best fit to a series of data points. Several methods exist, considering: Vertical distance: Simple linear regression
The line q in the p 1 direction is placed to go through an intersection Q x such that there are intersections in each half-plane defined by the line (median position). The constrained version of the enclosing problem is run on the line q' which determines half-plane where the center is located.
An example of planar straight-line graph In computational geometry and geometric graph theory , a planar straight-line graph (or straight-line plane graph , or plane straight-line graph ), in short PSLG , is an embedding of a planar graph in the plane such that its edges are mapped into straight-line segments.

Linear block codes are frequently denoted as [n, k, d] codes, where d refers to the code's minimum Hamming distance between any two code words. (The [ n , k , d ] notation should not be confused with the ( n , M , d ) notation used to denote a non-linear code of length n , size M (i.e., having M code words), and minimum Hamming distance d .)
An outcode is computed for each of the two points in the line. The outcode will have 4 bits for two-dimensional clipping, or 6 bits in the three-dimensional case. The first bit is set to 1 if the point is above the viewport. The bits in the 2D outcode represent: top, bottom, right, left.
