  2. Positional notation - Wikipedia

    en.wikipedia.org/wiki/Positional_notation

    The first position represents 10 0 (1), the second position 10 1 (10), the third position 10 2 (10 × 10 or 100), the fourth position 10 3 (10 × 10 × 10 or 1000), and so on. Fractional values are indicated by a separator , which can vary in different locations.

  3. Perspective (geometry) - Wikipedia

    en.wikipedia.org/wiki/Perspective_(geometry)

    Two perspective triangles, with their perspective axis and center. Two figures in a plane are perspective from a point O, called the center of perspectivity, if the lines joining corresponding points of the figures all meet at O. Dually, the figures are said to be perspective from a line if the points of intersection of corresponding lines all

  4. Position (geometry) - Wikipedia

    en.wikipedia.org/wiki/Position_(geometry)

    In geometry, a position or position vector, also known as location vector or radius vector, is a Euclidean vector that represents a point P in space. Its length represents the distance in relation to an arbitrary reference origin O , and its direction represents the angular orientation with respect to given reference axes.

  5. Perspectivity - Wikipedia

    en.wikipedia.org/wiki/Perspectivity

    This composition is a bijective map of the points of S 2 onto itself which preserves collinear points and is called a perspective collineation (central collineation in more modern terminology). [7] Let φ be a perspective collineation of S 2. Each point of the line of intersection of S 2 and T 2 will be fixed by φ and this line is called the ...

  6. Vanishing point - Wikipedia

    en.wikipedia.org/wiki/Vanishing_point

    A photo demonstrating a vanishing point at the end of the railroad. A vanishing point is a point on the image plane of a perspective rendering where the two-dimensional perspective projections of mutually parallel lines in three-dimensional space appear to converge.

  7. Notation system - Wikipedia

    Positional notation also known as place-value notation, in which each position is related to the next by a multiplier which is called the base of that numeral system Binary notation, a positional notation in base two; Octal notation, a positional notation in base eight, used in some computers; Decimal notation, a positional notation in base ten

  9. Isometric projection - Wikipedia

    en.wikipedia.org/wiki/Isometric_projection

    By rotating the cube by 45° on the x-axis, the point (1, 1, 1) will therefore become (1, 0, √ 2) as depicted in the diagram. The second rotation aims to bring the same point on the positive z -axis and so needs to perform a rotation of value equal to the arctangent of 1 ⁄ √ 2 which is approximately 35.264°.
