When surfacing fractured SDF fragments, the original unfractured SDF grid can be used to eliminate seam lines and tag polygons that are coincident with the reference surface with the POLYFLAG_EXTERIOR flag and polygons that are in proximity to the seam lines with the POLYFLAG_FRACTURE_SEAM flag. (The performance cost for using this reference based scheme compared to the regular meshing scheme is approximately 15% for the first fragment and neglect-able for subsequent fragments.)

Note

Attributes from the original asset such as uv coordinates, normals etc. are typically transfered to polygons that are marked with the POLYFLAG_EXTERIOR flag. Polygons that are not marked with this flag are interior to reference surface and might need projected UV coordinates or a different material. Polygons marked as POLYFLAG_FRACTURE_SEAM can be used to drive secondary elements such as debris and dust in a FX pipeline.

Parameters

grid	reference surface grid of GridT type.
secAdaptivity	Secondary adaptivity threshold [0 to 1]. Used in regions that do not exist in the reference grid. (Parts of the fragment surface that are not coincident with the reference surface.)
