View/Set 3D Layer Properties

Instructions

The Layer Properties command is 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, property values in the property panel, such as "Layer Title," will also change accordingly.

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

Entry Point

  • Scene tab -> Properties group -> Layer Properties option.
  • Layer Manager -> Layer right-click menu -> Layer Properties option.

Steps

In the "Layer Manager", select the layer whose properties you want to view or set. Click the "Layer Properties" button in the "Scene" tab > "Properties" group on the ribbon. The "Layer Properties" panel opens, allowing you to set parameters as needed.

Basic Parameter Settings

  1. Visible: Check the "Visible" checkbox to display all objects in the layer.
  2. Selectable: Check the "Selectable" checkbox to select objects for editing.
  3. Snappable: Check the "Snappable" checkbox to snap to vertices of layer objects. The current snap tolerance is 10 pixels.
  4. Editable: Check the "Editable" checkbox to select objects for object editing.
  5. Release Memory When Hiding Layer: Only applicable to 3D tile layers. This checkbox is activated only when the selected layer is a 3D tile layer. Check the "Release Memory When Hiding Layer" checkbox to release the layer's memory when hiding the 3D tile layer, reducing memory usage.
  6. Transparent Sorting: Only applicable to model tile layers. This checkbox is activated only when the selected layer is a model tile layer. Check the "Enable Transparent Sorting" checkbox to sort objects in the current model tile layer by their transparency.
  7. Participate in Excavation: Only applicable to tile layers with oblique photogrammetry models. This checkbox is activated only when the selected layer is a tile layer containing an oblique photogrammetry model. Check the "Participate in Excavation" checkbox to perform excavation on the oblique photogrammetry layer in the current layer.
  8. Accept Light: Only applicable to oblique photogrammetry layers and model tile layers. This checkbox is activated only when the selected layer contains an oblique photogrammetry layer or a model tile layer. Only when the "Visible" button in the "Browse" group of the "Scene" tab is activated, check the "Accept Light" checkbox to allow the current layer to receive light.
  9. Partial Transparency: Optimizes the display effect of models with partially translucent materials. The transparency optimization in scene properties must be enabled before use.
  10. Generate 3D Tiles: Only activated when the current layer data is a point/line/region dataset. Check the "Generate 3D Tiles" checkbox. When saving the workspace file as *.sxwu, a tag is added to the saved workspace to identify whether the tile type generated during dynamic tiling in iServer is S3MB.
  11. Vertex Color in Linear Space: Only available in 3D Scene Rendering Engine V2. This checkbox is activated only when the current layer data is a model dataset or a spatial 3D model tile data (*.scp), and is only applicable to data with ordinary materials. It is recommended to check this checkbox when the colors of data with ordinary materials appear different in the SuperMap iDesktopX scene compared to the source software. This converts vertex colors from linear space to gamma space, ensuring consistent color display.
  12. Dynamic Update: Only activated when the current layer data is S3M tiles. S3M tiles should be generated from a model dataset. When this checkbox is checked and the workspace containing the S3M tiles and corresponding model dataset is published 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.
  13. Shadow Mode: Shadow mode allows setting the display of object shadows under simulated sunlight. Options include: No Shadow and Show All Objects Shadow.
    • No Shadow: Shadows of all objects in the layer are not displayed.
    • Show All Objects Shadow: Shadows of all objects in the layer are displayed.
  14. Layer Name: Displays the layer name.
  15. Layer Title: By default, the layer name is used as the layer title, but it can be modified.
  16. Enable Sketch Display Mode: Only supported for CAD datasets. When checked, objects in the CAD dataset will be displayed in sketch mode.
Notes:
  • 3D Scene Rendering Engine V2 temporarily does not support enabling sketch display mode or displaying selected object shadows in shadow mode.

Filter Settings

Filter objects in the layer by setting a visible scale range or filter conditions.

  1. Minimum/Maximum Visible Height: Displays and sets the minimum/maximum visible elevation value of the current observation point relative to the objects in the 3D layer. If the elevation value of the current observation point in the scene is less than/greater than this elevation value, the objects in the 3D layer will be invisible. Unit: meters.
  2. Display Filter Condition: Used to set the display filter condition for the current layer, filtering which objects in the layer are displayed and which are not, allowing users to display features of interest and temporarily hide less important ones.
  3. Alpha Filter Threshold: Objects below the alpha filter threshold are not displayed.

Vector Parameter Settings

  1. Minimum/Maximum Visible Distance: Displays and sets the minimum/maximum visible distance value of the current observation point relative to model objects in the 3D layer. If the distance value of the current observation point in the scene is less than/greater than this distance value, the objects in the 3D layer will be invisible. Unit: meters.
  2. Visible Size (Pixels): Displays and sets the minimum visible pixel value of model objects in the current 3D layer. If the display pixel value of an object in the scene is less than this value, the object in the 3D layer will be invisible. Unit: pixels.
  3. Update Tile Count: Sets the number of tiles updated for data. The tile update count refers to the number of tiles refreshed each time the scene renders the layer. The larger the value, the faster the layer rendering, but it also consumes more hardware resources. It is recommended that users choose the value according to their machine configuration. The default value is 16, meaning 16×16 tiles are refreshed each time.
  4. Tile Side Length: Displays and sets the side length of tiles. Unit: meters.
  5. Buffer Distance (m): Sets the outward extension distance of a region layer when objects are attached.
  6. Rendering Mode: Each object has two faces based on vertex order. You can choose to render one face "Clockwise" or "Counterclockwise", or choose "Double-sided" to render both faces.

Polygon Offset Parameter Settings

  1. Offset Constant: Gets or sets the polygon offset constant. A positive value indicates the polygon is offset away from the screen; a negative value indicates the polygon is offset toward the screen.
  2. Scale Factor: The polygon offset constant and the polygon offset depth slope factor together determine the offset of polygon objects along the screen depth direction. Setting these values can resolve flickering issues when polygons overlap.

Application

  1. Auto Apply: Checked by default. When enabled, all parameter changes will be automatically applied to the layer without manual confirmation.

  2. Apply: After unchecking "Auto Apply", click the "Apply" button to apply parameter changes to the layer.
