Changelog

• 1.4 - 2016-06-05

  • renamed nodes.xml to functions.xml (format extended), contains defines, helpers and all code nodes
  • nodes can have a 'comment' attribute now which is displayed in the properties panel when the node is selected
  • function tags can have a 'requires' attribute now (name of other node or helper) to maintain code dependencies
  • Zwerg writes only required functions to the shader now (preparation for minify features)
  • renamed raymarcher.fs to shader.fs, moved optional code to functions.xml
  • integrated most operators of the Mercury SDF Library
  • PLEASE NOTE: Scene files created with earlier versions won't load because SDF function definitions have changed! The scene file format itself has not changed.

• 1.3 - 2014-06-15: external nodes.xml (contains all available nodes from scene view context menu), simplified internal tree structure and code cleanup, fixed: node order
