  • To review what a metaball is, and how to render them and to describe a new optimization I ve made

    To review what a metaball is, and how to render them and to describe a new optimization I ve made for rendering metaballs. For complex scenes, it can render hundreds of times faster, though I m certain others have discovered this trick as well. It does very slightly change the characteristic shape of the blobs, but there is no loss in image quality whatsoever. (I actually developed all this about two years ago, but just now felt like writing it all down, and had the time!)

  • Basic function to locate and measure the positive peaks in a noisy data sets. Detects peaks by loo

    Basic function to locate and measure the positive peaks in a noisy data sets. Detects peaks by looking for downward zero-crossings in the smoothed third derivative that exceed SlopeThreshold and peak amplitudes that exceed AmpThreshold. Determines, position, height, and approximate width of each peak by least-squares curve-fitting the log of top part of the peak with a parabola.

    Playfair Cipher 1.not even the large number of keys in a monoalphabetic cipher provides security 2.one approach to improving security was to encrypt multiple letters 3.the Playfair Cipher is an example 4.invented by Charles Wheatstone in 1854,but named after his friend Baron Playfair Playfair Key Matrix 1.a 5X5 matrix of letters based on a keyword 2.fill in letters of keyword (sans duplicates) 3.fill rest of matrix with other letters Encrypting and Decrypting -plaintext is encrypted two letters at a time 1. if a pair is a repeated letter, insert filler like X’ 2. if both letters fall in the same row, replace each with letter to right (wrapping back to start from end) 3. if both letters fall in the same column, replace each with the letter below it (again wrapping to top from bottom) 4. otherwise each letter is replaced by the letter in the same row and in the column of the other letter of the pair

  • SOME BACKGROUND ON DESIGN PATTERNS The term “design patterns” sounds a bit formal to the uninitiate

    SOME BACKGROUND ON DESIGN PATTERNS The term “design patterns” sounds a bit formal to the uninitiated and can be somewhat off-putting when you first encounter it. But, in fact, design patterns are just convenient ways of reusing object-oriented code between projects and between programmers. The idea behind design patterns is simple-- write down and catalog common interactions between objects that programmers have frequently found useful.

    Electronics Design Checklist C) 2003 Hank Wallace This is a checklist for electronics designers. The idea is for engineers and technicians to share experiences and create a detailed checklist, which the individual designer can pare down to meet his or her specific needs. There are many details that go into the making of a first-run design success, and this checklist helps prevent Murphy s gremlins from marring an otherwise healthy design.

    Some time during my development works I had the need of printing the contents of a ListView control. So I wrote down the code for a custom control, named PrintableListView, that solved the following two problems: * extend the print on multiple pages when the width of the list exceeds the width of the print page, * shrink, optionally, the list in a way that the resulting width fits o
