The spreadsheet contains 13 pages of 2048 rows and 256 columns. Cells of different pages could be cross-referenced. 3D Calc offers a GEM based user interface with icons, menus and function keys. Users can work on three spreadsheets at the same time with up to three GEM windows for each. The application supports on-screen help via the "?"
Mathematically, the gradient of a two-variable function (here the image intensity function) at each image point is a 2D vector with the components given by the derivatives in the horizontal and vertical directions. At each image point, the gradient vector points in the direction of largest possible intensity increase, and the length of the ...
Lucid 3-D was considered noteworthy at the time for being "the only major memory-resident spreadsheet available for the PC". [9] The selling point of the product was being "three dimensional. Any cell of the spreadsheet can contain a complete other spreadsheet that you can access with a single keystroke." [10]
VisiCalc was the first spreadsheet program but its release for the CP/M operating system ran only on the HP-125, Sharp MZ80, and the Sony SMC-70. SuperCalc was created to fill that void and market opportunity. Alongside WordStar, it was one of the CP/M applications bundled with the Osborne 1 portable computer.
Technically, it is a discrete differentiation operator, computing an approximation of the gradient of the image intensity function. At each point in the image, the result of the Sobel–Feldman operator is either the corresponding gradient vector or the norm of this vector. The Sobel–Feldman operator is based on convolving the image with a ...

Perlin noise is a procedural texture primitive, a type of gradient noise used by visual effects artists to increase the appearance of realism in computer graphics. The function has a pseudo-random appearance, yet all of its visual details are the same size. This property allows it to be readily controllable; multiple scaled copies of Perlin ...
