  2. Autostereogram - Wikipedia

    en.wikipedia.org/wiki/Autostereogram

    The depth level of each point in the combined image can be represented by a grayscale pixel on a 2D image, for the benefit of the reader. The closer a point appears to the brain, the brighter it is painted. Thus, the way the brain perceives depth using binocular vision can be captured by a depth map (Cyclopean image) painted based on coordinate ...

  3. Vergence - Wikipedia

    en.wikipedia.org/wiki/Vergence

    Convergence is one of three processes an eye does to properly focus an image on the retina. In each eye, the visual axis will point towards the object of interest in order to focus it on the fovea. [8] This action is mediated by the medial rectus muscle, which is innervated by Cranial nerve III. It is a type of vergence eye movement and is done ...

  4. Convergence tests - Wikipedia

    en.wikipedia.org/wiki/Convergence_tests

    If r < 1, then the series converges absolutely. If r > 1, then the series diverges. If r = 1, the root test is inconclusive, and the series may converge or diverge. The root test is stronger than the ratio test: whenever the ratio test determines the convergence or divergence of an infinite series, the root test does too, but not conversely. [1]

  5. Mandelbrot set - Wikipedia

    en.wikipedia.org/wiki/Mandelbrot_set

    The display center pans left from the fifth to the seventh round feature (-1.4002, 0) to (-1.4011, 0) while the view magnifies by a factor of 21.78 to approximate the square of the Feigenbaum ratio. The Mandelbrot set is self-similar under magnification in the neighborhoods of the Misiurewicz points .

  6. Plotting algorithms for the Mandelbrot set - Wikipedia

    en.wikipedia.org/wiki/Plotting_algorithms_for...

    From a mathematician's point of view, this formula only works in limit where n goes to infinity, but very reasonable estimates can be found with just a few additional iterations after the main loop exits. Once b is found, by the Koebe 1/4-theorem, we know that there is no point of the Mandelbrot set with distance from c smaller than b/4.

  7. Halley's method - Wikipedia

    en.wikipedia.org/wiki/Halley's_method

    Halley's method is a numerical algorithm for solving the nonlinear equation f(x) = 0.In this case, the function f has to be a function of one real variable. The method consists of a sequence of iterations:

  8. Vergence (optics) - Wikipedia

    en.wikipedia.org/wiki/Vergence_(optics)

    Vergence is measured in units of dioptres (D) which are equivalent to m −1. [1] This describes the vergence in terms of optical power . For optics like convex lenses, the converging point of the light exiting the lens is on the input side of the focal plane , and is positive in optical power.

  9. Prism fusion range - Wikipedia

    en.wikipedia.org/wiki/Prism_fusion_range

    The prism fusion range (PFR) or fusional vergence amplitude is a clinical eye test performed by orthoptists, optometrists, and ophthalmologists to assess motor fusion, specifically the extent to which a patient can maintain binocular single vision in the presence of increasing vergence demands.
