Quartz Composer - Native Datatypes

Native Datatypes

Data inside QC can be one of the following types:

  • Boolean - a boolean value, 0 or 1
  • Index - a positive integer between 0 and 2147483647
  • Number - a double precision floating point number
  • String - a unicode string
  • Color - an RGBA or CMYK quartet, or a Grayscale value
  • Image - a 2D image of arbitrary (possibly infinite) dimensions
  • Structure - a named or ordered collection of objects, including nested structures
  • Virtual - any of the above

Two additional types were introduced in version 4.0:

  • Mesh - a collection of vertices, and per-vertex normals, texture coordinates, and colors in 3-space
  • Interaction - a valueless type used to associate user input with user-interactive elements of the composition

Famous quotes containing the word native:

    “Of all my prosecutors ... not one is my peer, but each and all are my political sovereigns; and had your honor submitted my case to the jury, as was clearly your duty, then I should have had just cause of protest, for not one of those men was my peer; but, native or foreign born, white or black, rich or poor, educated or ignorant, sober or drunk, each and every man of them was my political superior; hence, in no sense, my peer.”
    —Susan B. Anthony (1820–1906)
