c# - about wiimote wrapper class -



c# - about wiimote wrapper class -

i'm interested in how working , looked @ code. of import part warp matrix construction done using computesquaretoquad , computequadtosquare functions, don't understand them. can explanation or give references that?

these 2 methods used translating photographic camera space coordination , display coordinates each other (computesquaretoquad translating photographic camera coordinates display , computequadtosquare reverse of it),

when @ world through camera, result flat image , distorted according perspective rules. (for illustration squares transform trapezoids). distortion can encapsulated warping matrix called planar homography.

you need 3x3 matrix calculation (note 4x4 matrix used because can integrated in 3d pipelines)

for more info have @
