The LoopRez script was created by Ged Larsen (math genius :P).I wrote a step-by-step tutorial on how to use Ged's wonderful LoopRez script in my blog at: http://slnatalia.blogspot.comHere are the settings for the 2 sample panels provided with the LoopRez v0.6 script."sample-short" creates a short skirt: objectName = "sample-short"
numObjects = 12
xRadius = .16
yRadius = .22
flareAngle = 45.0
bendCoefficient = 0.0
rotOffset = <0.0, 180.0, 0.0>
posOffset = <0.0, 0.0, 1.0>
"sample-long" creates a gown: objectName = "sample-long"
numObjects = 12
xRadius = .42
yRadius = .5
flareAngle = 45.0
bendCoefficient = 0.0
rotOffset = <0.0, 180.0, 0.0>
posOffset = <0.0, 0.0, 1.0>Note that both of these samples are designed to fit over an SL skirt (a skirt created under the Appearance... menu) with the following settings: Skirt Length: 30
Skirt Fit: 0
Bustle Skirt: 0Enjoy Ged's wonderful creation and I hope you will be making your own beautiful skirts soon! :)--Natalia Zelmanov
Loop Rez Script:
////////////////////////////////////////////////////////////////////////////////
// LoopRez v0.6, by Ged Larsen, 20 December 2006
//
// - rez a number of objects in an ellipse, whose size is determined by xRadius and yRadius
// - all facing "outwards", along a tangent to the ellipse
// - can set how much the objects flare outwards
// - properly handles object rotation corrections (for example, X-axis 180 degree rotation helps for flexi-prim skirts)
// - can also get a 'saddle' bend, to generate a bend that might help for necklaces (from Ariane Brodie)
//
// To use:
// 1) create a prim that will contain this script and the object to use
// 2) put the script into the prim
// 3) create an object that will be used, and name it "Object"
// 4) put "Object" into the prim containing the script, by dragging it from your inventory
// 5) get out of Edit Mode, and touch the prim
//
// Random note:
// - this version does NOT insure equal spacing of objects along the perimeter of the ellipse
// - i.e., objects "bunch up" at the long ends of an ellipse; the effect should be acceptable for non-extreme ellipses
// - even spacing of objects can be accomplished, but requires simulation of integral calculus, which slows down the script
//
// References:
// - tangent formulas from: http://mathworld.wolfram.com/Ellipse.html

vector rotOffset = <0.0, 180.0, 0.0>; // rotation offset in DEGREES -- fixes the rotation of ALL objects; for flexi prims, often you will want <180 .0, 0.0, 0.0>
