Click [Add Point] and select a position in the view. You can set a center point, and the program will record the current position and viewpoint.
The height of the center point can be adjusted by dragging the axis.
[Rotation Speed], [Rotation Count], [Rotation Direction], and [Estimated Time] are parameters that may control a video rotation effect.
Click [Play] to preview the video.
The [Frame Rate] parameter controls the video frame rate, and the [Resolution] parameter controls the video resolution.
To complete the video production, click on [Recording] and select the location where you want to save the video in the pop-up window.
This feature allows the user to capture the current screen display of the 3D Model Viewer and save it as an image file. This is useful for documenting a model's status, creating presentation materials, or sharing its appearance.
After the user clicks button, a dialog box appears for setting parameters related to the screenshot.
Image Size: In the dialog box, users can set the size of the output image to meet different needs.
Image Output Path: Users must specify a folder or path to save the screenshot file.
HD Image Output: After clicking [Export], the system outputs a high-definition image file according to the parameters set by the user.
Parallel and perspective projection: Users can choose whether to check the "export using parallel projection" option. When the option is checked, the view is temporarily converted to parallel projection mode for taking screenshots to achieve specific visual effects. The view automatically returns to perspective projection mode when the screenshot is finished.
Export DOM transforms the 3D model data into a 2D image map with geographic coordinate information, which is often called DOM (Digital Orthophoto Map) and DSM (Digital Surface Model). DOM is the orthographically corrected aerial film or remote sensing image, which has the characteristics of high accuracy, rich information, beauty, and practicality. At the same time, DSM describes the three-dimensional shape of the ground surface.
Users can quickly obtain the 2D image map with geographic coordinate information through the ortho map output function, providing basic data for subsequent map production and analysis.
Click the [Export DOM] button to set the output parameters.
Set the output path: Specify a folder as the output path of the DOM.
Select coordinate system: Select the appropriate coordinate system depending on your needs. Different coordinate systems may require different computing resources and time, and significant differences in coordinate systems may cause the output image to deform.
Set Resolution: Enter the desired resolution of the output image in centimeters. This determines the size of each pixel in real geographic space.
Select Background Color: Select the background color from the drop-down list. Options include black, white, and transparent (available for TIF format only).
Split Tiles: If you need to split the output, select the [Split Tiles] and set the split size in pixels.
Output DSM: If you need to generate Digital Surface Model files simultaneously, select the [Output DSM] option.
Model cropping is VIP feature, only available to member users.
The Model Cropping feature allows the user to crop the excess portion of the model to meet specific needs, leaving only the desired portion. This is useful when working with large or complex model data, especially when only certain areas of the model are needed.
Select the Clipping Area.
Users can import a kml format file as the clipping area, or use the screen drawing function to draw the clipping area directly on the model. When drawing, click [Screen Drawing] and left-click on the model to draw the area, and you can draw multiple surfaces. When you are finished drawing, click the [Eed Drawing] button. Drawing multiple faces means that various regions can be cut at once.
Select Model
Note that this model cropping function only supports the operation of models in osgb format.
Select Cutting Method
The system provides two cutting methods: inside [Delete Internal] and [Delete Extenrnal]. An inside cut involves removing the contents of the user's box, while an outside cut involves removing the contents outside the box. For cloud models, only the preview function is supported. For local models, users can choose between preview and actual model removal.
Setting Output Directory
After cropping, you must specify a folder to save the cropped model.
Crop Preview
Before cutting, you can preview the cut to see its effect. This preview operation is performed only at the display level and does not crop the original data. Users can restore the original display by clicking the "Restore" button in the upper left corner or unchecking the preview.
It is recommended that users preview the crop before performing it to ensure that it is as expected.
The Format Conversion feature allows users to easily convert between different 3D model formats to meet the needs of other platforms and applications. This feature is available only to registered and logged-in users to ensure they can use the conversion service safely and effectively.
OBJ is a common 3D model format, while OSGB is a proprietary format with higher loading efficiency and better browsing experience. Users can convert OBJ format to OSGB format by following the steps below:
Select the OBJ file or directory to convert.
Specify the OSGB output directory.
Select whether to rebuild the top layer data if necessary.
Select the supported texture format, one of jpg, dxt1, dxt3, dxt5 is recommended.
Set the texture quality; the recommended value is 90%.
Select node size and choose the appropriate size according to the model structure.
Choose whether to write normals or not (Note: writing normals will increase the file size by about 30%).
Click the Export button. After the conversion is finished, the generated OSGB data will appear in the output path.
Users can also convert OSGB format to OBJ format for other platforms or software use. The conversion process also supports the texture swing function, which can reduce the occupied storage space. The procedure is as follows:
Select the OSGB data path you want to convert.
Specify the output OBJ data path.
Select whether to perform texture mapping or not.
Click the Export button. After completing the conversion, view the generated OBJdataa in the output path.
3DTiles is a layered tile format for large-scale 3D terrain and model data, suitable for efficient loading and rendering on the web. Users can convert OSGB format to 3DTiles format for easy web presentation. The conversion steps are as follows:
Select the OSGB directory to be converted.
Select the output 3DTiles directory.
Select whether to rebuild the top layer data if necessary.
Select the supported texture format; one of jpg, webp, tx, or crn is recommended.
Set the texture quality; the recommended value is 90%.
Select whether to use vertex compression.
Choose whether to write normals or not (note: writing normals will increase the file size by about 30%).
Click the Export button. After the conversion is finished, you will see the generated 3D Tiles data in the output path.
Users can also convert 3DTiles back to OSGB format for use in other software that supports OSGB format. The conversion steps are as follows:
Select the 3DTiles file path to convert.
Specify the output OSGB data path.
Click the Export button. After the conversion is finished, you will see the generated OSGB data in the output path.
Coordinate conversion is VIP feature, only available to member users.
The coordinate conversion function allows users to convert the coordinate system of the source data to another coordinate system to meet the requirements of different application scenarios.
Set Source Data Path
Users need to select the OSGB or OBJ data path to be converted. The file organization should meet specific requirements to ensure the conversion's accuracy.
Set Input Coordinate System
When the user selects OSGB/OBJ data, the system automatically tries to read the coordinate system information from the data's Metadata.xml file. If the metadata file is not found or does not contain coordinate system information, the user must manually select or enter the appropriate coordinate system.
Set Input Coordinate Origin
Similarly, the system tries to read the coordinate origin information from the Metadata.xml file. If the data is missing, the user needs to provide it manually.
Set Output Data Path
Users need to select the output path of the converted data.
Set Output Coordinate System
Set Output Coordinate Origin
The user must set a new coordinate origin for the output data. The system will attempt to read the coordinate origin information from the source data, but the user can also edit and modify it as needed.
Set Conversion Method
The system provides four types of coordinate transformation to meet the needs of different scenarios:
No ellipsoid conversion required: It applies to transformation between different coordinate systems under the same ellipsoid.
Direct translation method: Allows users to input the translation amount of the xyz-axis to realize the direct translation of the coordinate system.
Four-parameter conversion: Applies to the transformation of any plane coordinate system with a point range within 10 kilometers. This transformation requires at least two control points and performs only plane transformation without changing the height information.
Seven-parameter conversion: This transformation requires at least three control points and involves both planar and elevation transformations for all point ranges more significant than 15 kilometers between different ellipsoids.
Submitting tasks
When the user has filled in all the necessary information according to the requirements, he can click the [Export] button to start the coordinate transformation. After the conversion, the user can find the converted OSGB/OBJ data in the specified output path.
Watermark is VIP feature, only available to member users.
Users can add text or image watermark to model files. This function effectively prevents the model files from being illegally copied or stolen and protects the rights and interests of the creators.
Text Watermark: When selecting a text watermark, users can customize its content, including text editing, font selection, color selection, and so on. In addition, users can adjust the watermark's visibility, rotation angle, horizontal spacing, and vertical spacing to ensure that it has the best visual effect on the model.
Image Watermark: To create an image watermark, users can select an image and make appropriate adjustments such as visibility, rotation angle, horizontal spacing, and vertical spacing. This way, users can add their logo or a specific image as a watermark to the model to further enhance its recognition and copyright protection.
Watermark Preview and Model Export: For local models, users can preview the watermark effect after adding the watermark. Users can export the model file with a watermark if the effect is satisfactory.
The user selects a specific set of tiles based on certain conditions or areas. Tiles often break up large maps or models into smaller, more manageable pieces.
Select All Tiles: This feature allows you to select all tiles in the currently displayed model with a single click, greatly facilitating quick manipulation of the overall data.
Cancel Selection: This function allows the user to deselect all or specific tiles when they are no longer needed.
Draw Selection: Users can select tiles by adjusting the range of boxes to be drawn, which is especially useful for scenarios that require tile data in a specific area.
Import Selection: This feature allows users to import external TXT, kml, and shp files and automatically detect and select the tiles corresponding to those files. It is useful for interacting with data from other systems or platforms.
Export Name Selection: The user can export the selected tiles to a txt file for further data processing or analysis.
Export Tiles Selection: Besides exporting the selection set, the user can directly export the raw data corresponding to the selected tiles to the destination folder. This feature is handy when you need data from a specific area, and it will also crop the model data between tiles.
Remove Tiles Selection: This feature allows users to remove selected tiles at the display level without affecting the original data. This means that when the user reloads the model, these tiles will be displayed again. In addition, the user can use the Esc key as a "clear" shortcut to quickly deselect tiles.
