to the 3D superplane of ω = 1. The resulting projection curve is:
Eliminate λ to obtain the rational beizer curve:
4. The effects of weighting factors
In addition to the properties similar to those of the bezr curve, the modified properties of the Weight Factor (weights) are also added.
4.1 recoverability
When the Weight Factor ω I = ω =0 (I = 0, 1,..., n), the rational beestimated curve degrades to the beestimated curve. Because ω is the same, the ω in the rational bezr curve formula can b

Preparation: ubuntu12.10has been successfully installed. The installation package contains the ns2installation file. Here I am using ns-allinone-2.33.tar and preparing two other patches:Tk-8.4-lastevent.patchAndTk-8.4.18-tkBind.patch
Step 1:Copy the ns2compressed package ns-allinone-2.33.tar.gz to the desktop, right-click and decompress it to the desktop, and copy the decompressed folder to the ready installation location,

For this security authentication method, the program can automatically enter the user name and password to achieve automatic login. Currently, objective CT, C, or Perl can be used. If C is used, you need to be familiar with the TCP/IP protocol, which is complicated to implement. if CT is used, because CT is based on Tcl, you need to be familiar with the Tcl
