• .print Saves this object to a graphical file. Directly saving a 3d object is a shortcut to putting it in the scene, selecting and placing a camera and choosing a renderer to the filename.

  This method is used to easily get images of an object: it allows some tuning as the parameters below shoe, but for the full control you probably want to place the object in a scene, define a camera and render it.

  • Parameters:
    • .filename: name of the file. Format will be inferred from the extension, if given
    • .format allows specifying the format. Overrides any extension
    • .size: size for the image, in pixels.
    • .outlook: a vector with the direction for the camera. Camera will be placed in a ray starting at the center at tha object and parallel to the vector given. Distance is regulated by the autoframe routine
    • .camera: allows setting the camera (with all parameters, position, aperture, etc)
    • .render: sets the rendering style. One of pov, phong.
  • See also: scene has, too, a quick-and-dirty print method that sets a camera and places it so it frames all the objects.
  • print is a function that focus the given object and prints it to a file. If the scene is more complex, all the objects in the focus will be included, unless the flag ..isolate is given.

  Note

  print could be a global function, that can be applied to any object
