Tiles in 3D view keeps on reloading, never finishes when too many visible #45353

Closed PeterBrodersen closed 2 years ago

What is the bug or the crash?

When viewing a huge point cloud layer in 3D the render keeps loading and discarding tiles.

A video recording of the issue is available here: YouTube Video https://www.youtube.com/watch?v=vpmHa-7Ajlk

Note the tile count at the top right. At some point it goes back and forth without ever loading everything in.

This also makes the generation of a QGIS animation with such an angle during the interpolation getting stuck and never getting past that frame. There is no error message, only the animation generation progress bar that never advances at a given point.

Steps to reproduce the issue

  1. Download a huge data set. I used a LAZ file of Amsterdam (2.5 GiB, which took a couple of hours to generate the EPT folder)
  2. View the data set in 3D (View -> New 3D Map View)
  3. Tilt the layer down to have many tiles in view

The pull request #47168 fixed this issue. It works fine in QGIS 3.26.
