VECTOR HOLOGRAM ITEMS

Hologram map — geometry

• Overhanging structures no longer read as solid wall down to the ground. Each column now carries a 64-level occupancy bitmask, and walls are raised only across spans that are actually solid. A cantilevered deck leaves open air beneath it; a solid tower stays solid. Both fall out of the same rule.
• Height is now true to scale. The vertical scale follows the horizontal one, so 40 m of tower is as tall as 40 m of ground is wide — at every radius. Previously the ratio changed with the range: roughly 2x stretched at the widest setting and 8x flattened at the closest.
• Resolution raised sharply at close and mid range. Sample counts: r=96 up 12x, r=48 up 3.2x, r=192 up 5.4x. Every scale is proven to fit the frame budget, so terrain never drops out — only fine detail thins.
• Terrain you have already seen is remembered, so panning the centre to a spot your client has not currently loaded shows the last known ground instead of a hole. Remembered ground is drawn dimmer than live ground.

Hologram map — new controls

• Round / Square island.
• Quality presets (ECO / STD / FINE) — scales the frame budget and the scan depth.
• Ceiling cut (off / +8 / +24 / +64 m above the projector) — look inside buildings, under forest canopy, or down into caves with one control.
• Layer filters — hide water, nature, built, or entities. Hidden material is seen through, not deleted: hide the leaves and the ground appears beneath them.
• Colour modes — NATURAL (material colour), CATEGORY (water / natural / built in three colours), HEIGHT (elevation ramp).
• Scale bar and altitude ladder on the deck, with the step size in the readout.
• Linking — set two or more projectors side by side and switch LINK on. Each shrinks its island to exactly one block and shows its own patch, so a 3x3 array covers nine times the area with no seam.
• Two more instrument tiles: TERRAIN (relief, band, cell size, ceiling) and TINT (what is hidden, quality, shape) — so when something is missing from the map, the map says why.

Surface

• Material colour is carried much further into the render, so surfaces read as real material while the image still reads as a hologram.
