View/Set 3D Layer Properties

Instructions for use

The Layer Properties command can be used to view or set the properties of the current layer. The current layer refers to the layer currently selected in the layer manager. As the current layer changes, properties such as "layer caption" in the properties panel will also change accordingly.

Depending on the layer type, the layer properties panel will display properties that can be viewed or set for the corresponding type.

Function Entries

The Scene tab -> Properties group -> Layer Properties option.
Layer Manager -> Layer context menu -> Layer Properties option.

Operation Steps

In the "Layer Manager", select the layer whose properties you want to view or set. Click the "Layer Properties" button in the ribbon > "Scene" tab > "Properties" group. The "Layer Properties" panel will pop up, where you can customize settings parameters as needed.

Basic Parameters Settings

Visible: Check the "Visible" checkbox to display all objects in the layer.
Selectable: Check the "Editable" checkbox to select objects for feature editing.
Snappable: Check the "Snappable" checkbox to select vertices of layer objects. The current snapping accuracy is 10 pixels.
Editable: Check the "Editable" checkbox to select objects for feature editing.
Release Memory: Only applicable to 3D tile layers. This checkbox is activated only when the currently selected layer is a 3D tile layer. Check the "Release Memory" checkbox to release the layer's memory when hiding the 3D tile layer, reducing memory usage.
Transparenct Sort: Only applicable to model tile layers. This checkbox is activated only when the currently selected layer is a model tile layer. Check the "Enable Transparenct Sort" checkbox to sort objects in the current model tile layer based on their transparency.
Excavation: Only applicable to tile layers with oblique photography models. This checkbox is activated only when the currently selected layer is a tile layer containing oblique photography models. Check the "Excavation" checkbox to excavate the oblique photography data layer in the current layer.
Receive Sunlight: Only applicable to oblique photography data layers and model tile layers. This checkbox is activated only when the currently selected layer is an oblique photography data layer or model tile layer. Check the "Receive Sunlight" checkbox to allow the current layer to receive sunlight, but only when the "Visible" button in the "Browse" group of the "Scene" tab in the ribbon is activated.
Partially Transparent: Optimizes display effects for models with partially translucent materials. Alpha optimization in scene properties needs to be enabled before use.
Build 3D Tiles: Only activated when the current layer data is a point/line/region dataset. Check the "Build 3D Tiles" checkbox to add a tag in the saved workspace when the save workspace file type is *.sxwu, identifying whether the tile type generated during dynamic tiling in iServer is S3MB.
Vertex Color Correction: Only available in the 3D Scene Rendering Engine V2. This checkbox is activated only when the current layer's data is a model dataset or spatial model tile data (*.scp), and it applies only to data with common materials. It is recommended to check this checkbox when data with common materials displays different colors in the SuperMap iDesktopX scene compared to the source software, as it converts vertex colors from linear space to gamma space to ensure consistent display effects.
Dynamic Update: Only activated when the current layer data is S3M tiles. S3M tiles should be generated from model datasets. When this checkbox is checked, after publishing a workspace containing S3M tiles and corresponding model datasets as a 3D service via SuperMap iServer, if the model dataset is updated, submitting an update request on the front end will dynamically update the corresponding S3M tiles on the front end.
Shadow Model: The shadow model can set the display of object shadows under simulated sunlight conditions. Options include: no shadows and display shadows of all objects.
- No shadows: Indicates that shadows of all objects in the layer are not displayed.
- Display shadows of all objects: Indicates that shadows of all objects in the layer are displayed.
Enable Sketch Mode: Only supports CAD datasets. When checked, objects in CAD datasets will be displayed in sketch mode.
Refresh When Enabled: Check the "Refresh When Enabled" checkbox to refresh the layer in real-time while editing layer properties.

Notes:

The 3D Scene Rendering Engine V2 does not currently support enabling sketch mode display or displaying shadows of selected objects in the shadow model.

Filter Settings

Filter objects in the layer by setting visible scales or setting filters.

- Minimum/Maximum Visible Height: Set display thresholds based on camera height.
- Display Filter: Only display objects filtered by the SQL statement.
- Alpha Filter Threshold: Objects below the alpha filter threshold are not displayed.

Vector Parameters

Minimum/Maximum Visible Distance: Set display thresholds based on the spatial distance between the camera and objects.
Tile Side Length: The side length of tiles.
Buffer Distance: The distance by which polygon layers extend outward when fitting objects.
Rendering Mode: Each object has two faces based on vertex order; you can choose to render one face "Clockwise" or "Counterclockwise", or select "Double-sided" to render all.

Polygon Offset Settings

Offset Constant: Get or set the polygon offset constant. A positive value offsets polygons outward from the screen; a negative value offsets them inward.
Scaling Factor: The polygon offset constant and polygon offset depth slope factor together determine the offset of polygon objects in the screen depth direction. Setting these can resolve flickering issues when polygons overlap.
