Re: Dodicat Zlib

@Albert. Why even ask? You know the answer will be NO. The FB forum is not the place for your ongoing attempts at data compression. Put simply: Do not post your attempts at compression on this website. There is no point posting code that does not actually work, or that has not been tested. No other ...

Re: Pentacles

To me, it is trivial algebra, in need of rationalization. It is difficult to rationalise the equation; angle = Pi * ( m + √n ); because that equation contains two irrational numbers. Any numerical constant would destroy the meaning. Each point on the sphere is placed at a longitude that is rotated ...

OK, so how could you rationalise it ?

angle = Pi * ( 3 + Sqr( 1.5 ) ) looks like it is coming up in the world.

Re: Pentacles

@jdebord. Well found. K was used for the colour in the plotting commands. It seems k got replaced with a constant 7 during a major edit, while I was changing colours to debug the 3D math. Have you tried adjusting the; angle = Pi * ( 3 - Sqr( 5 ) ) ? I wanted the simplest possible test bed for a few ...

Re: Pentacles

Or am i just going in circles?? It is clear that you were still going around in the same old circles you always do. And it seems this time you only received a 1 month ban. If you are wise you will find a school math text book and take a month to study an introduction to algebra. Then you could reco...

Re: Pentacles

When Albert writes and runs a line of code, he is arithmetically manipulating the numbers in the named containers. But a mathematician would process the symbolic algebraic equation, and immediately see the result. That explains the riddle of; A = B * A / B. To Albert that is a statement of simple ar...

Re: Pentacles

I'd plead more tolerance, sometimes sounds a bit like witch hunt. I believe we are remarkably tolerant. The science of data compression is defined by the mathematics of information. Albert does not understand the concept of high school algebra, and so cannot explain why A = B * A / B. One can have ...

Re: Pentacles

@albert. I would strongly suggest that you do not discuss your attempts at data compression in this thread, or on this website. We cannot help you with your data compression dreams. If you want to investigate data compression you need to do it somewhere else, or a moderator is going to have to decid...

Re: Pentacles

Welcome back Albert.
All you need now is a supply of free compressed air.
A trompe is a water-powered air compressor, commonly used before the advent of the electric-powered compressor.

Re: snow demo

You might think about at least 3 snow flake sizes to give it some depth. In my example the "closer" snowflakes are bigger and fall slower. Because of perspective, closer flakes will be bigger but cross the screen quickly, while distant flakes will be single pixels that appear to fall very...
