Confused about the "intersections" for texture synthesis

[RuihanGao]

Sec 3.2.1 of the paper mentions, "we place square scan arrays of 128 × 128 resolution on each tangent plane of the coarse mesh to obtain the intersections of the scanning rays with the mesh. " Does the last "mesh" refers to the coarse mesh or the fine mesh with meso-structure?

As far as I understand, the implementation is this part. The variable "intersections" is used for knn search, so sounds like the points on the fine mesh. However, it is obtained by the ray-tracing from scan rays to the coarse mesh.

Did I misunderstand something?

• "Mesh" refers to the coarse mesh, on which latent features locate.
• "intersections" on the coarse mesh can be directly utilized to fetch latent features as shown in here.
