class MAGES::MeshDeformations::AutoUV::PeelLayer¶

Overview¶

One depth-peel layer: a set of same-axis faces whose projected triangles are mutually non-overlapping. Backed by a coarse uniform 2D grid (over the axis’s projected bounds) storing face indices per cell, so a candidate is tested only against occupants of the cells its projected AABB touches. The layer’s own 2D bounds (Min/Max) become its packed island rect. More…

Detailed Documentation¶

One depth-peel layer: a set of same-axis faces whose projected triangles are mutually non-overlapping. Backed by a coarse uniform 2D grid (over the axis’s projected bounds) storing face indices per cell, so a candidate is tested only against occupants of the cells its projected AABB touches. The layer’s own 2D bounds (Min/Max) become its packed island rect.

Properties¶

float2 Min

Lower-left of the layer’s projected bounds (its island rect origin in projected space).

float2 Max

Upper-right of the layer’s projected bounds.

Methods¶

bool Overlaps(
    float2 a,
    float2 b,
    float2 c,
    int[] indices,
    float2[] projected,
    int[] stamp,
    int stampId,
    float epsilon
)

Returns whether the candidate triangle overlaps any face already in this layer. Uses stamp / stampId so each occupant is tested at most once even when it spans several of the AABB’s cells.

void Add(int face, float2 a, float2 b, float2 c)

Adds a face to the layer: grows the layer bounds and inserts it into every cell its AABB touches.
