Design, Implementation, and Testing of new language features for Diderot

Wish list

• Concatenation of fields ex. f = comp(f0,f1)
• Composition of fields ex. f= f0◦f1
• Definine fields as polys ex. f = x^2+y^2
• Constructive Solid Geometry ex. f= max(f0,f1)
• Clamp
• Define field with if/else statement
• Radial Basis functions ex. f (x_i, σ) = Σ_i ϕ{|x-xi|;σ}
• Define field by shifting ex. f = g(x+p(x))
• Selection If ex. f = selection(i, [f0,f1,f2,f3])

Organization of Directories

• Organized by topic (comp/concat/maxmin/polys/other)
  • In each directory
    • description of the implementation in "paper.pdf"
    • DATm found bugs and we save examples as regression tests in directories with the name ""X*"
  • Composition of fields in "comp/"
  • Concatenation of fields in "concat/"
  • Lerp/Clerp/Clamp in "other/"
  • Defining fields as polynomials in "polys/"
  • Max/Min/Abs in "maxmin/"
• Writeup of implementation and bugs found by DATm (writeup/paper.pdf)
• Nrrd files saved to ""data""
• dev directory is not ready to be viewed
• Fem has been moved to another repo.
