 26th February 2002, 20:05 #3 Mizter_E Rest Well Friend     Join Date: Jan 2002 Posts: 393 Ive always wondered what exactly do you need to know. Cuz there are functions involving r and d. so i know you're lying montana! Requiem aeternam dona eis, Domine et lux perpetua luceat eis. Respitae en pacem, Robert. 1985-2002

The biggest things I can see are understanding polar coordinates, radians, and trigonometric functions. But there are a lot of different things you can do with AVS that take more advanced math, or you can work in rectangular if you don't understand polar. I still don't know what the heck a sigmoid is, but my presets look fine. So, it really depends on what you want to do. Remember, you don't need any math to start out if you're not writing custom movements or superscopes. Then again, there's nothing wrong with the "type random equations and see what happens approach."
 28th February 2002, 14:31 #5 UnConeD Whacked Moderator     Join Date: Jun 2001 Posts: 2,104 Here you go: ```code: 1 __________ sigmoid(x, a) = -ax 1 + e ``` http://astronomy.swin.edu.au/~pbourk...d/sigmoid1.gif The function arises in differential math, but I'll spare you the gory details. You can view it as a constraining function which maps any value from (-infinity to +infinity) onto (0 to 1). As you can see from the definition, the parameter 'a' is simply a multiplication factor for the first parameter 'x'.

Thats what I usually end up doing

Perhaps I might have passed my Algebra/Geometry course. On secod thought, no. The teacher was just too boring. (sleeping during class does tend to have a detrimental affect on one's marks, though it did lead to the discovery of the pillow binder )

It won't be much more than (x = x + 0.1 ). Easiest level of geometry is the best you get there. Still, it is a nice preparation on the better parts of required math. .:HyperNation @ winamp:. .:DeviantArt:. Thermal is now available for download at DeviantArt.

It`s not that hard you`ll see PS.I sleep at languages hour,at math the teacher is VERY MEAN and gives us small grades,hard tests and makes fun of us...

Daemon, you do learn some useful math at school if you take the right courses. Trig is very useful, and computer math/science courses also have some interesting things.

 3rd April 2003, 21:58 #14 jheriko Forum King     Join Date: Aug 2002 Location: a twist in the fabric of space Posts: 2,150 Heres a list of the most useful math subjects I have found for AVS: Co-ordinate Geometry, Vectors, Matrices, Plane Geometry (In which I include Trigonometry), Solid Geometry, Calculus. A few of specific things from different areas that are useful are random numbers, linear/bilinear/trilinear/... interpolation, projective geometry, raytracing. Do some searches on the above using Google or something. -- Jheriko 'Everything around us can be represented and understood through numbers'

 13th April 2004, 18:02 #16 blaz Member     Join Date: Apr 2004 Location: Slovenia [EU] Posts: 69 well, I am a freshmen at AVS, and specialy Maths. I know the basic formulas like d=d+0.4, or x=cos(0.5) But I just can not understand something like this: d=log10(d*r-2+1/y*x/x+y)*sin(r*x+y/x*y+r) I just can not believe how you can do it. or, if someone, can tell my, how long did I take for him, to understand all of the maths. ---------------------------------------- I apologize if my English isn't good, I am from SLovenia, if you know where that is

One relief... I don't get it either.

Another thing:

That should give you a hint, and yeah, I know where Slovenia is.

There is no telling about how long it took, it comes with a piece at a time. Just start digging into some code that you think you might understand (try getting my Eye-Candy from my website (www-button)) this is still easy to understand.
Learn it and start fiddling around with your own imagination and you will grow day-by-day.
