Only those Layers should be active, which are necessary for the desired visualization purpose. Overlapping MapProxy Layers, such as base maps and orthophotos, should therefore be marked as exclusive in the View Settings (see Layers).
Reduce maximum zoom levels for image and terrain LayersAnchor
For each image and terrain Layer, the maximum zoom level should be adapted individually to the visualization purpose. Especially for complex 3D Views, the maximum zoom level is not required for each Layer. The highest zoom Level can be set for MapProxy and Terrain layers under "Edit Layer" in the Layer Configuration under "Advanced settings".
Individuelle Layer Empfehlung bei 3D-Mesh-Modellen:
Orthophotos associated with the mesh model: 18 - 19
Background maps or orthophotos of the surrounding area: 15 - 16
Seeding is the complete caching of an entire Layer. MapProxy is also functional without seeding, but seeding ensures that the individual tiles of a Layer can be delivered without delay.
Optimally, each MapProxy Layer should be seeded up to the maximum zoom level set. Seeding can be activated in the Layer Configurations under "Generate Tiles on Save". For high maximum zoom levels, the creation of the Layer can be very time-consuming and take several hours or days.
Therefore, for high maximum zoom levels and/or for MapProxy Layers with large areas, it may be useful to use the switchboard function "Seed subarea". This function requires as input parameters the desired Layer, as well as the Layer revision, a minimum and a maximum zoom level and a region as 2D feature. This function has the advantage that the process of seeding is limited to one region. In addition, the feature can also be applied to already created layers. In this case, already created layers can also be used already unseeded.
In the View settings, under the "Tools" tab, in the "3D Viewer" section, you will find various settings for the loading and tiling behavior of 3D tiles and image and terrain Layers.
The section shown in the following figure represents the recommended settings for a performant and yet detailed mesh model. The optimal settings for textured and for non-textured LOD2 models may differ.
The smaller this value is, the more detailed 3D tiles and image and terrain Layers are displayed in the depth of the image. For 3D tiles, the ScreenSpaceError should be between 30 and 80. For image and terrain layers between 1.5 and 4. To optimize performance and still present the 3D view as detailed as possible, the ScreenSpaceError should be increased gradually until the desired result is achieved.
This setting can also be defined individually for 3D tiles and external 3D tiles layers under "Edit Layer" in the Layer Configuration. In this case, the value in the layer configuration overwrites the value in the view configuration.
