what does "not watertight" mean?

• lambdaone 1y ago
  They don't create contiguous surfaces, and GPUs are optimized to deal with sets of triangles that share vertices (a vertex typically being shared by four to six triangles), rather than not shared at all as with this. "Watertight" is a actially a stronger criterion, which requires not only a contigous surface, but one which encloses a volume without any gaps, but "not watertight" suffices for this.

    Interesting thank you!
