@Dodicat Played a bit with the function plotter and made a weird circle of sorts... You can quite easily set a ball round this complex type of curve which is undefined for parts of the x range. I'll play around with this stuff and try some vectors. Dim As Integer xres,yres screeninfo xres,yres 'xre...

@Dodicat That's a very slick little minimalist function plotter you got going on there. It would be good to have something like that controlling the velocity vectors... The doodle is cool too... @ Rollie~ If you like the little macros, then here's the basic sketch, sketch with axis, and move. @ Alb...

Hi Albert here's a handy little function sketcher to save messing about with width() to see what it looks like. dim as integer xres,yres screeninfo xres,yres screenres xres,yres #macro sketch(_function,minx,maxx,miny,maxy) for x as double=minx to maxx step .01 dim as double x1=cdbl(xres&...

@Dodicat The problem with z's might be in the zsort, your not changing the impulses and mag=rgins when you do all the other swaping. Hi Albert The way you've got the timer, the box, the colours, there's no problem at all, I only suspected that the balls are going a little to far to the right, but t...

Re: Dodicats-bouncing_balls_3D

Hi Albert This one runs just fine on my old 933Mhz. And the new backddrop looks good, and the ball colours are cheerier than mine. I notice the balls are flying a bit too far on the right and bottom margins, so I'll change this later, I have to go up to Motherwell today to pick up an armchair for th...

I works perfect Dodicat; THANKS A BUNCH!!!!!!!!!!!. Are you working on backgrounds for the wall and back????? This is great!!! It runs a little slow with 100 balls slows down to a creeping halt almost, i'll have to something with the speed selector. Thanks for the test Albert. You'll have a job set...

Hi Albert Got the balls up and running with the Z component. Just a temporary backdrop at the moment. I've got the side bounces as an impulse now, much smoother. Also, I've mapped the z position to edge margins so the rebounds are only at the screen edge if the ball is maximum radius. 'ALBERT'S MARB...

@Dodicat How do you make the screen a 3D box with the farthest z smaller than the closest z so the balls can collide according to thier radiuses. the x and y neee to increment and decrement according to the z-axis , how do you do that???? Hi Albert I'll use rotate3d to get a mathematical z position...

That was a cool demo of the saw and board i saved it as:

Hi Albert
Richard's saw (in motion) would be the title.

The beauty of the Fourier transform is that it can make a caricature of anything by simply adjusting the coefficients of the terms. Nice saw. The integration's a bit of a pain to get the coefficients of a periodic shape you want, but that's because I'm a bit rusty, it's been a while since I've Four...

Hey guys, Has anyone collected a file with all the different ways to draw a circle, or at least as many as we could think of, different algorithms for generating? It would be cool to have them all in one place like that. Hi Rollie~ Here's a polynomial circle Function poly(coff() As Doub...

Hi all again Got the balls roughly guided by linear momentum rules. A mathematician might pick a fault or two, Stephen Hawking might not like it, but I'll put any imperfections down to a Quantum blip. I just kept your speed adjuster in Albert, although it runs a bit fast on my machine, I'll maybe ha...

Hi Albert I tried making everything a double I made a seperate seperation array In the end I just gave the impulse a slightly bigger whack, like you did (dividing by .707106 is just making the vector whack 1.4 times what it should be (I just made it 1.1) If the balls go Qnan then I reckon that just ...
