What’s new in CityEngine 2015.0?

CE2015 Splash Screen

It’s that time of year when a new release of CityEngine becomes available (okay we think it maybe the 9th of April)!  Yes we would love more bug fixes and features added, but they’re a small development team so we shall forgive them (this time…).  

As usual the Changelogs are publicly available here.

CGA Changelog

2015.0
CGAC 1.5
new functions:

changes to existing features:

  • split operations:
    • missing sizes are not allowed any longer. For instance, split(x) { A } does not compile anymore. The correct equivalent is split(x) { ~1: A }.
    • functions in size expression do not need extra parantheses anymore.
  • @Hidden annotation: changed propagation across imports. A hidden import hides all its imports recursively.
  • uid shape attribute deprecated. Use the getTreeKey function instead.

bugfixes:

  • Fixed a bug in the cgb decoder which failed to read compiled cga files with a large number of attributes/rules/splits.
  • Vertexmerger: fixed a bug which prevented hole vertices to be merged with vertices of other faces.
  • float() function: made string-to-float conversion independent of locale.
  • split operations: intensified internal mesh cleanup to reduce memory load, fixed a bug which led to undesired vertex-merges.
  • roofHip operation: avoid duplicate vertices.
  • offset, roofGable and roofHip operations: made offset / roof construction more stable on polygons with co-linear vertices and fixed a memory explosion bug.
  • cleanupGeometry operation: fixed bug which led to illegal material assignements (“filled holes rendering bug”) on edge cleanup for geometries with per-face-materials.
  • Fixed undefined behaviour if the same name was used for a scalar attr and a map attr.
  • CGA compiler: Parameteric rules and functions with a large number of parameters do not hang the compiler / CityEngine anymore.

note Selection behaviour change in UI changes behaviour of ce.selection(), ce.setSelection() in cases where shape has a model. To get the shape from a selection with shape and model, usece.getObjectsFrom(ce.selection, ce.isShape)[0] instead of ce.selection()[0]
