Linear Interpolation

Float Linear
Linear interpolation of f0 and f1 with fraction t. <lsl> float fLin(float f0,float f1,float t) { return f0*(1-t) + f1*t; } </lsl> Input Description float f0 Start (t = 0.0) float f1 End (t = 1.0) float t Fraction of interpolation Output Description return float fLin Returns linear interpolation of two floats Released to Public Domain.

Vector Linear
Linear interpolation of v0 and v1 with fraction t. <lsl> vector vLin(vector v0, vector v1,float t){ return v0*(1-t) + v1*t; } </lsl> Input Description vector v0 Start (t = 0.0) vector v1 End (t = 1.0) float t Fraction of interpolation Output Description return vector vLin Returns linear interpolation of two vectors Graph goes here, k.

Rotation Linear

Spherical Linear interpolation of r0 and r1 with fraction t. Also known as SLERP <lsl> rotation rLin(rotation r0,rotation r1,float t) { float ang = llAngleBetween(r0, r1); if(ang > PI) ang -= TWO_PI; return r0 * llAxisAngle2Rot( llRot2Axis(r1/r0)*r0, ang*t); } </lsl> Input Description rotation r0 Start (t = 0.0) rotation r1 End (t = 1.0) float t Fraction of interpolation Output Description return rotation rLin Returns spherical linear interpolation of two rotations Graph goes here, k.

Vector List, Linear

Interpolates between two vectors in a list of vectors. <lsl> vector pLin(list v, float t, integer Loop ){ float l = llGetListLength(v); t *= l-1; float f = (float)llFloor(t); integer i1 = 0; integer i2 = 0; if(Loop){ i1 = (integer)(f-llFloor(f/l)*l); ++f;i2 = (integer)(f-llFloor(f/l)*l);} else { if( f > l-1 ) i1 = (integer)l-1; else if( f >= 0 ) i1 = (integer)f; if(f+1 > l-1 ) i2 = (integer)l-1; else if(f+1 >= 0 ) i2 = (integer)f+1; } vector v1 = llList2Vector(v, i1); vector v2 = llList2Vector(v, i2); return vLin( v1, v2, t-f );} </lsl> Input Description list v A path of vectors. float t Interpolation, Start 0.0 - 1.0 End. integer Loop Whether the list loops over. Output Description return vector pLin Returns a vector that is the linear interpolation of two vectors between 't'. Graph goes here, k. Released to Public Domain. By Nexii Malthus
