Introduction to several commonly used software for 3D model 3DTile format lightweight compression processing tools
The lightweight processing of the 3D model 3DTile format is designed to reduce the storage space of the model and improve rendering performance. Here are some recommended software tools that can be used for this purpose:
MeshLab: MeshLab is an open source 3D model processing software that supports the import and export of multiple formats, including 3DTiles. Through its built-in mesh simplification, cropping, smoothing and other functions, users can perform lightweight processing on 3D models. In addition, MeshLab also provides advanced features such as texture mapping and normal calculation, making it widely used in professional fields.
Cesium ion: Cesium ion is an online service that provides the function of converting many common formats (such as .obj, .glTF, etc.) to 3DTiles format. At the same time, it also automatically performs optimization and compression to reduce the output file size. Cesium ion's cloud processing feature allows users to complete the conversion without installing any additional software on the local machine, which is very convenient.
FME: FME is a powerful data conversion and integration tool that supports over 450 different formats of data, including 3DTiles. In addition to basic model conversion, FME also provides a series of processing tools, such as mesh optimization, coordinate transformation, etc., which can help users complete complex lightweight processing tasks.
ContextCapture: This is a software developed by Bentley Systems, mainly used to create and edit three-dimensional city models. ContextCapture supports generating 3D models from a variety of sources (such as drone images, lidar point clouds, etc.) and can be exported to multiple formats such as 3D Tiles. During the generation process, the software automatically performs optimization and compression operations to ensure the performance of the final model.
Agisoft Metashape: Metashape is a professional-level photogrammetry and three-dimensional reconstruction software developed by Agisoft. Users can easily generate 3D models from photos or lidar data, and select the corresponding optimization level during output to control the quality and volume of the final model.
Pix4Dmapper: As a professional drone data processing software, Pix4Dmapper can easily generate accurate 3D models from images collected by drones, and supports output to a variety of formats, including 3DTiles.
K3DMaker: 3D Factory K3DMaker is a professional processing software with functions such as 3D model browsing, analysis, lightweighting, top-level merge construction, geometric correction, format conversion, color correction and cropping. Operations such as mesh simplification, texture compression, and level optimization of 3D models can be performed to achieve lightweight 3D models. The lightweight compression ratio is large, the model is lightweight and efficient, and the automatic processing capability is high; a variety of algorithms are used to perform geometric precision correction processing on the 3D model, with high accuracy, fast processing speed, and support for ultra-large models; excellent data processing and conversion tools support the Convert OSGB format 3D models to 3DTiles and other formats, which can be quickly converted. Come and experience it. See the illustration for the download address.
The above tools and software have their own characteristics and advantages, and users can choose according to specific needs and scenarios. It should be noted that when performing lightweight processing, the complexity of the model should be appropriately reduced while ensuring the quality of the model to achieve the best performance and visual effects.
