Image Synthesis


  • Note about the movies; I like to play them in reverse in a loop - definitely play in a loop though, its how I designed them.
  • The movie for degree 4 b-spline filter is available here
  • The movie for a point sample is available here

resolution of the function: L(x,y) = 0.5(1 + sin(x*x + y*y)) Use the
Mitchell filter, and b-spline filters of degree 0,1,2,3,4. Turn in the
six figures as a web page. Extra Credit Create a movie for the best
filters of the function: L(x,y) = 0.5(1 + sin(x*x + y*y + k*t) )
where t is time and k is a constant. 
Changes made:
point sample and:
function L(x,y) changed to .5*1+sin(.01*x*x +.01*y*y))
