The 3D tile
generates an OSGB or S3M or S3MB format cache file from the model data (model dataset or CAD) in the data source at one time, and loading this model cache can greatly improve the model browsing performance and display effect.
Batch generate model cache
Open the data source;
3D data tab, 3D tile group, generate cache drop-down menu-Batch generate cache button, pop up the batch generate model cache dialog box;
add data set;
confirm the added data set;
parameter setting
cache name : The default is the same as the data source name;
cache path
:; tile side length: display and set the size of the tile side length;
field setting: used to set the attribute field for generating the 3D tile cache, all field information is generated by default;
texture compression format : Set the purpose of the generated scene cache, mainly used for common PC devices, iOS series devices, Android series devices, etc.;
no compression: the default texture format;
WebP: applicable to the general compressed texture format on the Web/PC;
DXT (PC device): applicable to the general compressed texture format on PC (personal computer);
CRN_DXT5 (PC device): applicable to the general compressed texture format on PC (personal computer);
PVRTC (iOS series devices): applicable Common compressed texture format for Apple iOS devices;
ETC (Android series devices): Common compressed texture format for Android devices;
Texture settings: multiple textures and single textures;
number of threads: the default is 4;
Pyramid subdivision type: set the subdivision type of the tree pyramid created by the cache slice. The application provides two methods
: quadtree and octree; filter threshold: used to set the parameters for filtering the sub-objects of the coarse layer, the default is 2. The unit is pixel;
object field ID: the field used to set the unique identification ID, select by the drop-down arrow;
file type: the file type is S3MB data format;
vertex weight mode: provide none, data set field, shortest edge of triangle and original feature There are four ways of value;
vertex optimization method: only when the vertex weight mode is none, the vertex optimization method can be set;
feature value: this option is available only when the data set field is selected as the vertex weight mode;
texture sharing, with normal, with Wireframe, repeated texture grouping, and instantiation: the default check box with normal and repeated texture grouping;
tile range: set the "cache range" area;
LOD level setting: used to set the number of LOD levels for the cache;
net Lattice simplification rate: refers to the simplification of the details displayed by the corresponding LOD layer model according to the percentage;
after generation, *.scp is the cache configuration file, and indexData.dat is the cache index file;
note that the
tile edge length determines the number of cache root nodes: edges The larger the length, the fewer the root nodes; on the contrary, the smaller the side length, the more root nodes, and the longer it takes to generate the cache. When there are too many root nodes, the loading model will be slow to a certain extent.
The number of LOD levels has an impact on the smoothing effect of switching when the model is displayed;
Open iServer service scene
Open iServer service scene command, used to open a scene published through iServer service;
right-click the scene collection node in the workspace manager, and select the "open iServer service scene" command in the pop-up right-click menu; open iServer service scene dialog box, enter the information of the iServer service scene to be opened in the dialog box, and click the "OK" button to open the iServer service scene;
service address: enter the service address published by the scene;
scene name: enter iServer The name of the published service scene. The scene name must be consistent with the name when the scene is published;
when the scene service is requested to open, its URL (iServer service address) is:
http://service address:port number/iserver/services/realspace -Workspace name /rest/realspace,
