Re: [Nel] multipart meshes, deforming, adding

[Andi 'Debug' Allen]

Heh,

 

thanks for your reply didn't touch on more than 1% of my questions or give any real

solutions and practices sounded cool though so ty

 

the main part of this questions where about mesh interfacing breaking up a mesh into

parts that is already bound to a skeleton then using mesh deformation or swap

in swap out to change them.

 

just after some step by step

some how to's

do's and don'ts

code samples

3ds advice for creating of them

process for building them

Hello Andi,

 

If I am following what you are wanting to do then the way it is usually done is skeletal animation.

The idea is much like a human, bones have a certain effect on the skin. So instead of animating the mesh you create a skeleton for the person and then put a skin (or mesh) on top of the skeleton.

After you have created a skeleton you then have to assign weights (how much the joint effects this vertex) to the vertecies for each joint ( you don't want a knee joint effecting the arms ). Now you can animate the skeleton and change the skin as you feel the need.

This is quite useful for any human type of actions such as walking. You can us mathmatics to define how an impact such as taking a step would effect the bones and the skin automatically follows.

 

Later, Ben

Hi,

 

ok we have been thinking seriously about this for some time

and as yet have failed to come up with even an iterim solution.

 

in games such as ryzom and anarchy online etc.

 

although this falls into game development theory i feel if

it has been done in ryzom or by someone who uses nel a

heads up on the methods would be very useful

 

a player can wear different pieces of armour hold different weapons

the armours can be differnt sizes and shapes.

 

the logical method that presented itself to me is to break a model

of a char into various parts head / neck / arm etc and hot swap

replacement meshes for those parts.

 

how then does the animation deal with these replacements

or even additions! to a mesh like a cape or over armour armours

 

im probably on the wrong track entirely.... arent i

 

and you want to tack a weapon mesh onto a char or shield

 

we are extremly lost on ways to proceed and dont want to make

to many meshes before we know the hoes and whys of proven

systems.

 

so to break it up we need some kind of reasonable idea of how to

do the following

 

link / unlink / rotate / scale - weapon / shield / con to a character

mesh without breaking animation

 

change / scale - armour parts to replace parts of a char mesh

without breaking animation.

 

is there a set system for doing this in NeL i dont want to reinvent the

wheel again.

 

thanks
