  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. Belief merging - Wikipedia

    en.wikipedia.org/wiki/Belief_merging

    The utilitarian rule (minimizing the sum of distances) will choose x1,x2,x3,x4; this is unfair to the minority expert, who is not represented at all. The egalitarian rule (minimizing the maximum distances) will choose x1,x2,y1,y2; this is unfair to the majority experts, who are represented by only 2 out of 4 propositions, even though they are 3 ...

    For independent random variables X and Y, the distribution f Z of Z = X + Y equals the convolution of f X and f Y: = ()Given that f X and f Y are normal densities, = (;,) = / () = (;,) = / ()

    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.

  6. 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.

  7. Cross-lagged panel model - Wikipedia

    en.wikipedia.org/wiki/Cross-lagged_panel_model

    With these four measures, there are six possible relations among them – two synchronous or cross‐sectional relations (see cross‐sectional design) (between X1 and Y1 and between X2 and Y2), two stability relations (between X1 and X2 and between Y1 and Y2), and two cross‐lagged relations (between X1 and Y2 and between Y1 and X2)."

  8. Pinhole camera model - Wikipedia

    en.wikipedia.org/wiki/Pinhole_camera_model

    The plane which is spanned by axes X1 and X2 is the front side of the camera, or principal plane. An image plane, where the 3D world is projected through the aperture of the camera. The image plane is parallel to axes X1 and X2 and is located at distance f {\displaystyle f} from the origin O in the negative direction of the X3 axis, where f is ...

  9. Line–line intersection - Wikipedia

    en.wikipedia.org/wiki/Line–line_intersection

    First we consider the intersection of two lines L 1 and L 2 in two-dimensional space, with line L 1 being defined by two distinct points (x 1, y 1) and (x 2, y 2), and line L 2 being defined by two distinct points (x 3, y 3) and (x 4, y 4). [2] The intersection P of line L 1 and L 2 can be defined using determinants.
