Instructions for use

This tool can be used to generate 3D Gaussian Splatting data (*.ply) into S3M 3.01 tile data.

Parameter Description

Parameter Name Parameter Description Parameter Type
Select Folder Select the folder where the source data is located. All 3D Gaussian Splatting data (*.ply) in the specified folder will participate in the operation.
Each subdirectory under the specified folder will be treated as a group. The entire folder without a subdirectory is a group.		 String
Tile Name:
(Optional)		 Sets the name of the result tile data. The default is pointCloudCacheResult. String
Storage Path: Sets the storage path for the resulting tile data. String
Pyramid Split Type:
(Optional)		 Sets the pyramid subdivision type of the resulting tile data. Options include Quadtree and Octree. The default is QuadTree. PyramidSplitType
Vertex Optimization Method:
(Optional)		 Sets how vertices are optimized for the resulting tile data.
  • No compression: The data is not compressed.
  • Draco Cpmression: Compress Dataset based on a certain algorithm can significantly reduce the amount of data and improve the data loading experience.
  • MeshOpt Compression: Uses a series of algorithms to reduce the complexity of the data grid, thereby reducing the amount of data and improving the efficiency of data rendering.
MeshCompressType
Data Unit:
(optional)		 Sets the data unit, including meters, degrees, centimeters, millimeters, inches, and feet. The default value is Meter. DataUnit
Insertion Point X
(Optional)		 Sets the X coordinate value of the insertion point (i.e., the geographic reference origin) of the data. The default is 0. Double
Insertion Point Y
(Optional)		 Sets the Y coordinate value of the insertion point (i.e., the geographic reference origin) of the data. The default is 0. Double
Insertion Point Z
(Optional)		 Sets the Z coordinate value of the insertion point (i.e., the geographic reference origin) of the data. The default is 0. Double
Rotation Angle (XYZ):
(optional)		 Sets the euler angle, in degrees, by which the data is sequentially rotated about the X/Y/Z axes. The format is: X, y, Z. For example: 0,0,0. String
Source Projection (EPSG):
(optional)		 Enter the EPSG code for the coordinate system where the source data resides. Integer
Target Projection (EPSG):
(optional)		 EPSG code of the coordinate system where the input result tile data is located, e.g. 4490. Integer
Transformation Method
(Optional)		 Sets the method for projection transformation of the data. Including:
1. Geocentric three-parameter transformation method Geocentric Translation (3-para): applicable to geocentric-based three-parameter Coordinate Transformation.
2. Molodensky conversion method Molodensky (3-para): Molodensky three-parameter conversion method.
3. Simplified Molodensky transformation method Abridged Molodensky (3-para): Three-parameter transformation method.
4. Position vector method Position vECTOR (7-para): one of the seven parameter conversion methods.
5. Coordinate Frame (7-para), a seven-parameter conversion method based on the earth's core.
6. Bursa-Wolf (7-para): a commonly used seven-parameter conversion method.
7. MolodenskyBadekas Projection Transformation Method MolodenskyBadekas (10-para): a ten-parameter spatial Coordinate Transformation model.
8. Three-dimensional seven-parameter conversion method China _ 3D _ 7P (7-para): used for conversion between different coordinate systems and the National Geodetic Coordinate System 2000 (CGC2000). It is applicable to Coordinate Transformation of control points between geodetic Coordinate Systems under different earth ellipsoid datum of 3 degrees and above of national and provincial ellipsoid. The conversion method involves three translation parameters, three rotation parameters and one scale change parameter, and simultaneously needs to consider two earth ellipsoid semi-major axes and the flattening difference corresponding to the two geodetic coordinate systems.		 CoordSysTransMethod
Projection Transformation Parameters
(Optional)		 Sets the parameters for projection transformation of data, including scale difference, rotation angle, offset, rotation origin, etc. The specific parameter values are specified by the Projection Transformation parameter tool. CoordSysTransParameter
