Allows all layer types (including vector, mesh and point cloud)
providers to show custom metadata in the layer properties dialog.
Previously this was limited to raster/vector tile and tiled
scene layers only.
Also fix const for a lot of raster providers as a consequence.
to use when scenes have no textures available for some primitives
Since there's no way to determine in advance whether or not a scene
will actually have textures, this prevents the non-ideal situation
arising where no content is shown on the map because we default
to the texture renderer and don't have any textures to draw.
- added QgsTiledSceneTile::baseUrl() to get URL that generated the tile and thus
base URL for resolving relative paths of linked content
- resolution of relative URLs should work also when sub-tree JSON files are in
a different path than the root tileset JSON
- all content URLs are now using scheme - URLs of local files start with file://
- removed duplicated code to resolve relative URLs in GLTF parsing and chunk loading
We currently offer three renderer choices:
- Textured (default). Loads the texture image and paints the mesh using
these textures
- Texture color. Uses the center point color for rendering each mesh
triangle. Gives a clear visual overview of the mesh structure while
also providing some context via the texture color
- Mesh. Renders the scene's mesh using a fill symbol
bounding volumes as OBB
Greatly simplifies the code. There's a small loss of efficiency
since we will always be expanding out spheres to their bounding
boxes, but given we always require boxes for QGIS 3d nodes
anyway this will only impact 2d rendering.
