View/Set 3D Layer Properties

Description

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, property values such as "Layer Caption" in the property panel will also change accordingly.

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

Functional Entry

Scene Tab -> Properties Group -> Layer Properties option.
Layer Manager -> Layer Right-click 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 pops up. Customize the parameters as needed.

Basic Parameter Settings

Displayable: Check the "Displayable" checkbox to display all objects in the layer.
Selectable: Check the "Selectable" checkbox to select objects for object editing.
Snappable: Check the "Snappable" checkbox to select the vertices of layer objects. The current snapping precision is 10 pixels.
Editable: Check the "Editable" checkbox to select objects for object editing.
Release Memory When Hidden: Applicable only to 3D tile layers. This checkbox is activated only when the currently selected layer is a 3D tile layer. Checking the "Release Memory When Hidden" checkbox allows the system to release the memory of that layer when the 3D tile layer is hidden, reducing memory usage.
Transparency Sorting: Applicable only to model tile layers. This checkbox is activated only when the currently selected layer is a model tile layer. Checking the "Enable Transparency Sorting" checkbox sorts the objects of the current model tile layer based on their transparency.
Participate in Excavation: Applicable only to tile layers containing oblique photography models. This checkbox is activated only when the currently selected layer is a tile layer containing oblique photography models. Checking the "Participate in Excavation" checkbox allows excavation to be performed on the oblique photography layers within the current layer.
Receive Lighting: Applicable only to oblique photography layers and model tile layers. This checkbox is activated only when the currently selected layer is an oblique photography layer or a model tile layer. Checking the "Receive Lighting" checkbox allows the current layer to receive lighting only when the "Visible" button in the "Browse" group of the Ribbon's "Scene" tab is activated.
Partial Transparency: Optimizes the display effect of models with partially translucent materials. Enabling transparent optimization in the scene properties is required before use.
Generate 3D Tiles: This checkbox is activated only when the current layer data is a point/line/region dataset. Checking the "Generate 3D Tiles" checkbox adds a tag to the saved workspace when the workspace file type is *.sxwu. This tag indicates whether the tiles generated during dynamic tiling in iServer are of type S3MB.
Vertex Color is Linear Space: Only available for 3D Scene Rendering Engine V2. This checkbox is activated only when the current layer's data is a model dataset or spatial 3D model tile data (*.scp), and it applies only to data with standard materials. It is recommended to check this checkbox when data with standard materials displays different colors in the SuperMap iDesktopX scene compared to the source software. This will convert vertex colors from linear space to gamma space, ensuring consistent data color display.
Dynamic Update: This checkbox is activated only when the current layer data is S3M tiles. The S3M tiles should be generated from model datasets as source data. When this checkbox is selected, after publishing a workspace containing S3M tiles and the corresponding model datasets as a 3D service via SuperMap iServer, if the model dataset is updated, submitting an update request from the front-end will dynamically update the corresponding S3M tiles on the front-end.
Shadow Mode: Shadow mode can set the display of object shadows under simulated sunlight conditions. Options include: No Shadow and Show All Object Shadows.
- No Shadow: Indicates that shadows for all objects in the layer are not displayed.
- Show All Object Shadows: Indicates that shadows for all objects in the layer are displayed.
Layer Name: Displays the layer name.
Layer Caption: The layer name is used as the default layer caption, which can be modified.
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 does not currently support enabling sketch mode display or showing selected object shadows within shadow mode.

Filter Settings

Filter objects in the layer by setting visible scales or setting filter conditions.

- Minimum/Maximum Visible Height: Displays and sets the minimum/maximum visible elevation value between the current observation point and 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 this 3D layer will become invisible. The unit is meters.
- Display Filter Condition: Used to set the display filter condition for the current layer, filtering which objects in the layer can be displayed and which cannot. This facilitates users in displaying features of interest and filtering out temporarily unnecessary ones based on their needs.
- Alpha Filter Threshold: Objects below the Alpha filter threshold are not displayed.

Vector Parameter Settings

Minimum/Maximum Visible Distance: Displays and sets the minimum/maximum visible distance value between the current observation point and the 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 this 3D layer will become invisible. The unit is meters.
Visible Size (Pixels): Displays and sets the minimum visible pixel value for model objects in the current 3D layer. If the display pixel value of an object in the scene is less than this pixel value, the objects in this 3D layer will become invisible. The unit is pixels.
Update Tile Count: Sets the tile update count for the data. The tile update count refers to the number of tiles refreshed each time when the scene renders the layer. A larger value results in faster layer rendering speed but also consumes more hardware resources. Users are advised to select the size of this property based on their own machine configuration. The default value is 16, meaning 16×16 tiles are refreshed each time.
Tile Edge Length: Displays and sets the size of the tile edge length, in meters.
Buffer Distance (m): Sets the outward extension distance for region layers in the case of object pasting.
Rendering Mode: Each object has two faces based on its vertex order. You can choose to render one face as "Clockwise" or "Counterclockwise", or choose "Double Sided" to render both.

Polygon Offset Parameter Settings

Offset Constant: Gets or sets the polygon offset constant. A positive value indicates the polygon is offset outward from the screen; a negative value indicates it is offset inward.
Scale Factor: The polygon offset constant and the polygon offset depth slope factor together determine the offset amount of polygon objects in the screen depth direction. Setting these can be used to resolve the flickering issue when polygons overlap.

Apply

Auto Apply: Checked by default. When enabled, all parameter modifications will be automatically applied to the layer without manual confirmation.
Apply: After unchecking "Auto Apply", modified parameters require clicking the "Apply" button to be applied to the layer.
