Package dev.engine_room.flywheel.backend.engine

Class LightStorage

java.lang.Object
dev.engine_room.flywheel.backend.engine.LightStorage
All Implemented Interfaces:
Effect
public class LightStorage extends Object implements Effect
A managed arena of light sections for uploading to the GPU.

Each section represents an 18x18x18 block volume of light data. The "edges" are taken from the neighboring sections, so that each shader invocation only needs to access a single section of data. Even still, neighboring shader invocations may need to access other sections.

Sections are logically stored as a 9x9x9 array of longs, where each long holds a 2x2x2 array of light data.
Both the greater array and the longs are packed in x, z, y order.

Thus, each section occupies 5832 bytes.

    • visualize

      public EffectVisual<?> visualize(VisualizationContext ctx, float partialTick)
      Description copied from interface: Effect
      Create a visual that will be keyed by this effect object.
      Specified by:
      visualize in interface Effect
      Parameters:
      ctx - The visualization context.

    • sections

      public void sections(it.unimi.dsi.fastutil.longs.LongSet sections)
      Set the set of requested sections.

      When set, this will be processed in the next frame plan. It may not be set every frame.

      Parameters:
      sections - The set of sections requested by the impl.
