Point Cloud Surface

Point Cloud Surface reconstructs a controllable 2.5D mesh from a Blender Point Cloud or mesh vertices. It is intended for floors, roads, walls, facades, and other surfaces that can be represented as one depth over a fitted plane.

Workflow steps

  1. Select a Point Cloud or vertex mesh and use it as the source.
  2. Choose Best Fit, world-axis, or object-axis projection.
  3. Set percentage or cell-size resolution and a hard vertex safety budget.
  4. Choose Triangles, Quad Dominant, or Grid Quads.
  5. Optionally enable Density-Adaptive Detail and set Density Weight plus Refinement Levels.
  6. Configure representative depth, gap preservation, smoothing, thickness, UVs, and shading.
  7. Generate a new surface or update the previously managed output.

Important details

Density-Adaptive Detail leaves larger cells in sparse areas and subdivides densely sampled areas. A weight of zero is spatially uniform; a weight of one is fully density-driven. The vertex budget remains a hard cap, and Grid Quads stays uniform to avoid T-junctions.

Triangles preserve exact unique points at 100 percent when the safety budget permits. Quad Dominant merges compatible triangle pairs. Grid Quads averages regular cells and can fill small holes or add boundary triangles.

This is a height-field reconstruction. Build floors, walls, overhangs, and overlapping depth layers as separate surfaces when they cannot share one projection plane.
