ObliqueBuilder - Generate S3M

Instructions for use

The tool can use SCP config file as the source data, and through texture compression, lightweight, rebuild the top level and other operations. You can generate oblique photography model data as S3M tile data. By loading S3M tile data, the efficiency of data loading can be improved and the multi-terminal sharing and interoperation of data can be realized.

This tool is usually used with Generate Config Files and Oblique Builder - Singulation . ObliqueBuilder - Generate Normals、ObliqueBuilder - Modify Center Point、 ObliqueBuilder - Clipping and other GPA tools.

To use this tool in the Windows operating system, you need to meet certain hardware and software requirements:

  • Be compatible with OpenGL 3.0 or below;
  • Supports shader syntax below GLSL (OpenGL Shading Language, OpenGL Shader Language) 1.30; The video memory of
  • Video card is greater than 1GB.

Parameter Description

Parameter Name Parameter Description Parameter Type
Source Config File Add source SCP config file. The config file is available through a Generate Config Files tool based on oblique photography model data. String
Unite Layers
(Optional)		 When the number of config files in the file list is greater than or equal to 2, through Unite Layers, You can generate a new config file from multiple config files by merging multiple data layers into one data layer.
Note: Checking this box will modify the source data. It is recommended to back up the data before processing it.		 Boolean
Storage Path: Sets the file path to save result data. String
Process Thread Count:
(optional)		 The number of threads assigned to this operation. The number of threads is set to 0, which means that the number of threads allocated to the operation is the maximum number of cores on the current computer. Integer
Rebuild Top Level
(Optional)		 Sets whether rebuild the top level processing occurs. For the oblique photography 3D data with poor top-level effect, the finer level data can be re-designated as the new root node, and then the Rebuild the top level can improve the top-level visualization effect, reduce the amount of data, and improve the loading efficiency. Boolean
Compressed Type:
(Optional)		 Use different texture compression formats for different purposes of data to reduce the amount of video memory used by texture images, including WebP, DXT, CRN _ DXT5, and KTX2.0.
  • WebP: It is recommended to select this value when Tile Data is used on the mobile side, and transparent texture is supported.
  • DXT: When this value is selected, Result Data has the smallest video memory occupation, the shortest processing time, and the largest total amount of data.
  • CRN _ DXT5: When this value is selected, the result data takes up slightly less video memory, takes the longest processing time, and has the largest amount of data.
  • KTX2.0: When this value is selected, result data is available on both PC and mobile terminals. The mobile terminal does not support transparent textures
Note: In iServer 11.1.1 and above in the Linux environment, the corresponding parameter value needs to be set according to whether the node depends on multiple concurrency.
  • The Texture Compression type cannot be set to CRN _ DXT5 if the node depends on multiple concurrency.
  • If the node does not depend on multiple concurrency, all parameter values can be set. However, if the Texture Compression type is to be set to CRN _ DXT5, it is necessary to temporarily comment out the LD _ PRELOAD parameters in the product package/bin/setenv. Sh file by using the # symbol before starting the iServer, so as to ensure normal generation of the Tile. Failure to do so may result in an exception to the Tile generation process and failure to generate Result Data.
TextureCompressType
Storage Type:
(optional)		 Results Storage type for Tile Data, both raw and compact.
  • Raw means that the data is not compressed and the original information is retained.
  • Compact means that a mechanism is used to compress and encrypt the Tile Data.
Currently, only the source data is OSGB, which supports the generation of Tile Data in a compact format.		 StorageType
Vertex Optimization Method:
(Optional)		 Sets the vertex optimization method for the data, including No Compression, Draco Cpmression, and MeshOpt Compression.
  • 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.
VertexOptimizationType
S3M Version:
(optional)		 Sets the version of S3M tile data, including: S3M 1.0, S3M 2.0, S3M 3.0, S3M 3.01. S3MVersion
Lightweight
(Optional)		 Sets whether to perform the Lightweight process. When the Lightweight check box is checked, you can simplify the geometry and texture objects of the data and reduce the amount of data in Result Data after Oblique Import. Boolean
Texture Remapping
(Optional)		 Set whether to perform Texture Remapping for data. It is not checked by default. Texture Remapping can solve the unreasonable situation of Splice Texture in some Oblique Photography Model data, thus improving the performance of data line selection. Boolean
Watermark Parameter Settings
(Optional)		 Sets the add watermark parameters, as specified by the Watermark Parameter Settings tool. WatermarkParameters
Cloud Storage Connection
(Optional)		 Set whether to upload result S3M data to Cloud Storage (Huawei Cloud, Alibaba Cloud, SeaweedFS, MinIO, AWSS3). The specific parameters are specified by the cloud storage connection tool. CloudStorageConnectionInfo
Target Coordinate System
(Optional) Target Coordinate System for		 Tile Data. IDesktopX can be set by the Set Coordinate System, Copy Coordinate System, and Import Coordinate System operations. The iServer can be set by entering the EPSG Code of the Specify Coordinates system. Integer
Scale Difference:
(optional)		 Projection Transformation parameter that represents the amount of scale expansion from the original coordinate system to the new coordinate system. Double
