  2. 3x3 basketball - Wikipedia

    en.wikipedia.org/wiki/3x3_basketball

    3x3 basketball (stylized as ƐX3, pronounced three-ex-three) [1] is a variation of basketball played three-a-side, with one backboard and in a half-court setup. This basketball game format is currently being promoted and structured by FIBA, the sport's governing body. [2]

  3. Charts on SO (3) - Wikipedia

    en.wikipedia.org/wiki/Charts_on_SO(3)

    The various charts on SO(3) set up rival coordinate systems: in this case there cannot be said to be a preferred set of parameters describing a rotation. There are three degrees of freedom, so that the dimension of SO(3) is three. In numerous applications one or other coordinate system is used, and the question arises how to convert from a ...

  4. Euler angles - Wikipedia

    en.wikipedia.org/wiki/Euler_angles

    The axes of the original frame are denoted as x, y, z and the axes of the rotated frame as X, Y, Z.The geometrical definition (sometimes referred to as static) begins by defining the line of nodes (N) as the intersection of the planes xy and XY (it can also be defined as the common perpendicular to the axes z and Z and then written as the vector product N = z × Z).

  5. 3D rotation group - Wikipedia

    en.wikipedia.org/wiki/3D_rotation_group

    The Killing form for the rotation group is just the Kronecker delta, and so this Casimir invariant is simply the sum of the squares of the generators, ,,, of the algebra

  6. Nomogram - Wikipedia

    en.wikipedia.org/wiki/Nomogram

    A Smith chart to calculate electrical impedance with no values plotted; although not a nomogram, it is based on similar principles. Like a slide rule, a nomogram is a graphical analog computation device. Also like a slide rule, its accuracy is limited by the precision with which physical markings can be drawn, reproduced, viewed, and aligned.

  7. Multiview orthographic projection - Wikipedia

    en.wikipedia.org/wiki/Multiview_orthographic...

    Comparison of several types of graphical projection, including elevation and plan views. To render each such picture, a ray of sight (also called a projection line, projection ray or line of sight) towards the object is chosen, which determines on the object various points of interest (for instance, the points that are visible when looking at the object along the ray of sight); those points of ...

    The South Korea men's national 3x3 team is the 3x3 basketball team representing South Korea in international men's competitions. The team won the silver medal in the men's tournament at the 2018 Asian Games held in Jakarta, Indonesia.

  9. Rodrigues' rotation formula - Wikipedia

    en.wikipedia.org/wiki/Rodrigues'_rotation_formula

    This form may be more useful when two vectors defining a plane are involved. An example in physics is the Thomas precession which includes the rotation given by Rodrigues' formula, in terms of two non-collinear boost velocities, and the axis of rotation is perpendicular to their plane.
