Constant Field Values

POST_AA

public static boolean POST_AA

Use Fast Approximate Anti-Aliasing (FXAA) and Screen Space Ambient Occlusion (SSAO).

RAW_DATA

public static boolean RAW_DATA

Use real time calculations to pre-process data.

TRANSLUCENT

public static boolean TRANSLUCENT

Let vanish extrusions / meshes which are covered by others. RenderBucket.EXTRUSION: roofs are always translucent.

To better notice the difference, reduce the alpha value of extrusion colors in themes.
