I know two lines intersect, but I have to find the position where they do. Anyone have some code for this?
--EDIT--
I figured it out. This doesn't check for identical lines, but it works for what I need:
Method Intersects:TVec3( t:TLine,tolerance#=0.001 )
Local wx#=x-t.x
Local wy#=y-t.y
Local wz#=z-t.z
Local a#=dx*dx+dy*dy+dz*dz
Local b#=dx*t.dx+dy*t.dy+dz*t.dz
Local c#=t.dx*t.dx+t.dy*t.dy+t.dz*t.dz
Local d#=dx*wx+dy*wy+dz*wz
Local e#=t.dx*wx+t.dy*wy+t.dz*wz
Local q#=a*c-b*b
Local st#=b*e-c*d
Local tt#=a*e-b*d
Local tx#=wx+(st*dx-tt*t.dx)/q
Local ty#=wy+(st*dy-tt*t.dy)/q
Local tz#=wz+(st*dz-tt*t.dz)/q
If tolerance<>-1
If tx*tx+ty*ty+tz*tz>=tolerance*tolerance Return
EndIf
tx#=wx+(st*dx)/q
ty#=wy+(st*dy)/q
tz#=wz+(st*dz)/q
Return vec3(tx,ty,tz).plus(vec3(t.x,t.y,t.z))
EndMethod
