hi,i am new to github. 2012-7-19

i always implement some algorithms in my project, it's very cool to share the code with others i think. feel free to join me :) 2012-7-24

note: most of the code can't be directly used or compiled in your porject, but it's easy to integrate.

##Computer Graphics

• biovision hierarchical data(BVH) parsing
• cubic bezier control points
• cubic bezier curve
• principal component analysis(PCA)
• rotate point about arbitrary axis
• spherical linear interpolation(slerp)

##Piecewise Code

• exponent of double value
• three-dimensinoal-point operations redirect to cubic bezier control points

##Sortings

• quick sort redirect to PCA
