#72830 - 2003-02-02 11:18 PM Need math/geometry help.
Radimus Radimus Moderator Registered: 2000-01-06 Posts: 5187 Loc: Tampa, FL	given a line with coordinates x1:y1 to x2:y2 I need a way to find the coordinates at some point at any given percent of the length for example, $segment=drawpercent($fromx,$fromy,$tox,$toy,50) $segx=$segment[0] $segy=$segment[1] TIA [ 03.

Lonkero Lonkero KiX Master Guru Registered: 2001-06-05 Posts: 22346 Loc: OK	eh, I understand percent and I understand coordinates, but your code makes my head fuzzy... could you explain little more what you want, please, thanks. _________________________ ! download KiXnet

Lonkero Lonkero KiX Master Guru Registered: 2001-06-05 Posts: 22346 Loc: OK	k, this should do: function splitPoint($xb,$yb,$xe,$ye,$p) $splitPoint=($xe-$xb)$p/100+$xb,($ye-$yb)$p/100+$yb endfunction _________________________ ! download KiXnet

Radimus Radimus Moderator Registered: 2000-01-06 Posts: 5187 Loc: Tampa, FL	ok... that worked perfectly. Thanks Pt. 2. This should be a bit harder... given a point, and a length, and a 360 degree direction find the point. $point=angleline($x,$y,$radius,$angle) $nextx=$point[0] $nexty=$point[1] _________________________ How to ask questions the smart way <-----------> Before you ask

Lonkero Lonkero KiX Master Guru Registered: 2001-06-05 Posts: 22346 Loc: OK	or am I again trying to think it too hard... is all that you want the coordinate of the destination in specified distance at specified direction? _________________________ ! download KiXnet

Radimus Radimus Moderator Registered: 2000-01-06 Posts: 5187 Loc: Tampa, FL	any X,Y coordinate on the screen/image map... positive integer Yep from a given point, in a given 0-359 degree angle, at a specified distance. find the x,y coordinates at that point _________________________ How to ask questions the smart way <-----------> Before you ask

Shawn Shawn Administrator Registered: 1999-08-13 Posts: 8611	the angles can be any number between 0-359 or is it more granular, like increments of 10 degrees ?

Lonkero Lonkero KiX Master Guru Registered: 2001-06-05 Posts: 22346 Loc: OK	was crashing my head when realized that you said they are positives... might not even need pure cos... I'm coding something in my head... not sure how well does it work... _________________________ ! download KiXnet

not tested this is...
at least tested the sides code... a little.

check out does it work or not...
no external dependencies.

function coord($x,$y,$dist,$deg)
dim $
select	case $deg=0	$coord=$x,$y+$dist 
	case $deg=90	$coord=$x+$dist,$y
	case $deg=180	$coord=$x,$y-$dist
	case $deg=270	$coord=$x-$dist,$y
	case $deg<90	$=sides($dist,$deg)	$coord=$x+$[1],$y+$[0]
	case $deg<180	$=sides($dist,$deg-90)	$coord=$x+$[0],$y-$[1]
	case $deg<270	$=sides($dist,$deg-180)	$coord=$x-$[1],$y-$[0]
	case 1		$=sides($dist,$deg-270)	$coord=$x-$[0],$y+$[1]
	endfunction

function sides($1,$2)
dim $,$3
$1=0.0+$1*$1
$3=90.0-$2
do $=0.01+$ until $1<($*$2)*($*$2)+($*$3)*($*$3)
$sides=$*$3,$*$2
endfunction

{edit}
updated code.

Lonkero Lonkero KiX Master Guru Registered: 2001-06-05 Posts: 22346 Loc: OK	as a btw... what bigger the distance is that better should the accuracy be but also that longer it should execute... not sure, should I make it return in some percentage accuracy? _________________________ ! download KiXnet

Bryce Bryce KiX Supporter Registered: 2000-02-29 Posts: 3167 Loc: Houston TX	hey!! what is this complex math stuff!!! because everyone knows, kixtart is just a logon script language.... i knew that someone would find a use for the sqrt () Function

Lonkero Lonkero KiX Master Guru Registered: 2001-06-05 Posts: 22346 Loc: OK	bryce, had to skip it it probably is the reason why my script does not perfectly work... or floating points overlapping... this seems to be harder task than I quessed... _________________________ ! download KiXnet

Lonkero Lonkero KiX Master Guru Registered: 2001-06-05 Posts: 22346 Loc: OK	ok, found the minor problem in there... fixed code above. for those who might even care, my own made sin/cos function had a failure in it. _________________________ ! download KiXnet

NTDOC NTDOC Administrator Registered: 2000-07-28 Posts: 11631 Loc: CA	Can't help Lonkero.. not too good at that math. Seems IE 3.0 keeps giving me error. Microsoft JScript runtime error In frame: msncomv8 [Line: 108] get Cookie is undefined I guess IE 3.0 does not like the KiXtart chocolate chip cookies.
