Esri CityEngine 2023

Terrain rendering performance is dramatically increased through adaptive rendering. Terrains are now always rendered at maximum resolution. There is no need anymore to manually set the resolution of elevation maps in order to have rendering at interactive rates.

The resolution field in the Terrain Inspector is removed and high-res elevation maps are not limited to 1K anymore by default.

 

New brush for terrain editing

In addition to the Terrain Edit Brush and Terrain Reset Brush, there is now a Terrain Smooth Brush that allows the smoothing of hard edges and artifacts in the original elevation data or after manual edits.

With CityEngine 2023.0, we introduce a new way to use instances of imported rulesets.

On import, rulesets are “instantiated” once, meaning their attributes are initialized, depending on override parameters in the import statement. The new dynamic imports feature allows you to temporarily instantiate (and therefore parameterize) a ruleset at any place in the code. The temporary ruleset instance can be parameterized with values only available at runtime and allows for using a rule in the ruleset once.

This gives you better flexibility for reusing and customizing rule files and modularizing your CGA code.

Check the new dynamic imports tutorial for an example; the import statement in the CGA reference for more details; and the CGA changelog for more information on improvements in CGA.
