HttpDataSetLODsLoader

Source (.js)Source (.d.ts)

Introduction

vtkHttpDataSetLODsLoader progressively downloads a list of increasingly detailed versions of the same dataset and swaps each one into a mapper as it becomes available, so a coarse representation is displayed while the finer ones are still being fetched.
