Inverse Kinematics

[susanta]

If you like to design your own IK system for greater control and flexibility this article is for you (if you are planning to design in-house rigging system like biped or cat)...it explains the standard IK system with simple mathematical formulas (applied approach...not complicated theory). It is very easy to follow this article and can be easily implemented with any language.

hey susanta,

thanks for this article,
because I have a book on maya API programming but its limited to surface and polygon creations,
and all college level books are mostly on rendering pipeline and GPU architecture,
so I was so looking for this,

one more thing,
We have developed a pose manager for our project using MEL,
but now we want it to upgrade to Motion Library, like we can do in Motionbuilder,
but what I was wondering was that while working with native scripting language there are lots of limitations where we have to limit ourselves with lack of MEL commands and output formats,
So what I thought was it would be better if we can create our own format to store and retrieve data(animation data), that way we can better handle data structures also,
just like Kaydara did, FilmBox format became Motionbuilder base,

what do you think?

thank again for that article,
and will post you more with codes,
and I have blog where I keep posting my Python scripts for asset management tasks,

Nice…keep forward. But one humble advice…calculate the development time frame before moving for a new format development. Just take look (May be you already did) on Collada (http://www.collada.org), it is open source. FBX is nice and it has its free SDK…but I’m afraid you will not like it (http://usa.autodesk.com/adsk/servlet/index?siteID=123112&id=8224901) I think you prefer open source.

I saw your blog…cool. Nice to see your affinity towards open source (wxwidgets???) … Another link for you because you like python as well…. http://cgkit.sourceforge.net/
