  2. Rasterisation - Wikipedia

    en.wikipedia.org/wiki/Rasterisation

    Raster graphic image. In computer graphics, rasterisation (British English) or rasterization (American English) is the task of taking an image described in a vector graphics format (shapes) and converting it into a raster image (a series of pixels, dots or lines, which, when displayed together, create the image which was represented via shapes).

  3. 2D to 3D conversion - Wikipedia

    en.wikipedia.org/wiki/2D_to_3D_conversion

    Most semiautomatic methods of stereo conversion use depth maps and depth-image-based rendering. [4] [5] The idea is that a separate auxiliary picture known as the "depth map" is created for each frame or for a series of homogenous frames to indicate depths of objects present in the scene. The depth map is a separate grayscale image having the ...

  4. Right angle - Wikipedia

    en.wikipedia.org/wiki/Right_angle

    The straight lines which form right angles are called perpendicular. [8] Euclid uses right angles in definitions 11 and 12 to define acute angles (those smaller than a right angle) and obtuse angles (those greater than a right angle). [9] Two angles are called complementary if their sum is a right angle. [10]

  5. Special right triangle - Wikipedia

    en.wikipedia.org/wiki/Special_right_triangle

    For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°. This is called an "angle-based" right triangle. A "side-based" right triangle is one in which the lengths of the sides form ratios of whole numbers, such as 3 : 4 : 5, or of other special numbers such as the golden ratio.

  7. Polygon triangulation - Wikipedia

    en.wikipedia.org/wiki/Polygon_triangulation

    [9] [10] [11] Bernard Chazelle showed in 1991 that any simple polygon can be triangulated in linear time, though the proposed algorithm is very complex. [12] A simpler randomized algorithm with linear expected time is also known. [13] Seidel's decomposition algorithm [10] and Chazelle's triangulation method are discussed in detail in Li ...
