Detailed Description

Base class for ribbons. If can be used to compute ribbons trajectory. It can perform lagrange or linear interpolation. to get the ribbon shape. It can also be used to have fixed size ribbons. NB : Ribbons that don't herit from this are deprecated but may be kept for compatibility.

void NL3D::CPSRibbonBase::computeHermitteCstSizeRibbon (  uint  index,

)  [private]
 

Compute the ribbon points using hermitte splines between each sampling point, and make a rough approximation to get a constant lenght

Our goal here is to match the length of the ribbon, But if it isn't moving fast enough, we must truncate it Having a constant speed over a hermite curve is expensive, so we make a (very) rough approximation...

The same as compute linear ribbon but try to make its length constant.

Our goal here is to match the length of the ribbon, But if it isn't moving fast enough, we must truncate it

compute length between the 2 sampling points

compute lambda so that it match the length needed for each segment

compute a location

go to next sampling pos
