  2. Line drawing algorithm - Wikipedia

    en.wikipedia.org/wiki/Line_drawing_algorithm

    dx = x2x1 dy = y2y1 m = dy/dx for x from x1 to x2 do y = m × (x − x1) + y1 plot(x, y) Here, the points have already been ordered so that >. This algorithm is unnecessarily slow because the loop involves a multiplication, which is significantly slower than addition or subtraction on most devices.

  3. Digital differential analyzer (graphics algorithm) - Wikipedia

    en.wikipedia.org/wiki/Digital_differential...

    The DDA method can be implemented using floating-point or integer arithmetic. The native floating-point implementation requires one addition and one rounding operation per interpolated value (e.g. coordinate x, y, depth, color component etc.) and output result.

    The (x2-x1)(y2-y1) term is the area of the whole rectangle, and, for instance, the (x-x1)(y-y1) is the area of the rectangle opposite Q_22. That would hold to higher dimensions: In trilinear, the weights of each component are proportional to the size of the opposing volume.

  5. Liang–Barsky algorithm - Wikipedia

    en.wikipedia.org/wiki/Liang–Barsky_algorithm

    In computer graphics, the Liang–Barsky algorithm (named after You-Dong Liang and Brian A. Barsky) is a line clipping algorithm. The Liang–Barsky algorithm uses the parametric equation of a line and inequalities describing the range of the clipping window to determine the intersections between the line and the clip window.

    y=f(x)=.5x+1 or f(x,y)=x-2y+2=0 Positive and negative half-planes. The slope-intercept form of a line is written as = = + where is the slope and is the y-intercept. Because this is a function of only , it can't represent a vertical line.
