The commonly used 3D design software on the market can directly reduce the surface or install additional plug-ins before reducing the surface. But there will always be times when it is not easy to use, such asOptimization is not satisfactory, including loss of model detail, broken faces, distortion or deformation, some of which will when dealing with large modelsIt's stuck and even crashes directly
I believe that some small partners have also tried outsourcing to find someone to reduce the surface, but**ExpensiveNot to say, and it is quite possible that it will still be after many rounds of communicationNot up to the mark, and time was spent, tooThe construction period was delayed
Here, I would like to recommend the one developed by our companyDomestic software - Tianyuan software, it's oneProfessional 3D model optimization softwareIt supports more than 60 3D model file formats, so the mainstream design software and industry on the market can basically be covered.
When it comes to domestic software, don't dislike it first, maybe you can try it first, just support domestic products, and then see how the processing effect is, maybe it's the law of true fragrance?
Our team has also reduced the surface of two different formats of vehicle models before, and has also compared them with mainstream design software, let's take a look at the effect:
The first is: a vehicle model in FBX format
YesMore than 1.28 million noodles, directly use the web version of Tian Yuan Software (Official Website**:) to optimize. Models in this format can be used directly".Super Reduced Surface LOD".function. After 3 simple steps, reduce the dough to350,000 faces
The second type is: CAD model files in STEP format
Here we willTian Yuan Softwareand UE4Datasmith pluginsCompare the effect of surface reduction.
1. UseUE4Datasmith pluginOptimize.
After installing the plugin, we upload the CAD file and then adjust the desired reduction scale by setting the chord tolerance and normal tolerance. Here we setThe chord tolerance is 001cm, the normal tolerance is 20 degrees
Note: The lower these two values, the higher the number of triangles, the higher the accuracy of the model.
PassedUE4Datasmith pluginThe final number of faces is approximate300,000, andThere are many broken surfaces and uneven wiringIt is difficult to apply to projects
2. UseTian Yuan SoftwareOptimize.
Similarly, let's log on to the official website of Tian Yuan (）。However, for CAD model files with non-polygon data such as the STEP format, we use the function of "differential CAD". In the same step, after 3 simple steps, Tianyuan Software completed the optimization of the model.
Note: In contrast to the optimization of the UE4Datasmith plugin, we set the parameter chord tolerance to be consistent with the normal tolerance, i.e. the chord tolerance is 01mm, the normal tolerance is 20 degrees.
After observation, we saw that the number of three faces of the model optimized by Tianyuan software was about 100,000 faces, almostI can't see the broken face, andUniform wiring。After attaching the material to the original modelThere is not much difference between the twoAlmostI can't see the difference。This kind of processing effect can be well applied to the project.
So, after comparison, both in terms of the number of optimized surfaces and in terms of optimization effect,Tianyuan software is relatively superior to the UE4Datasmith plugin.
Many friends may deal with more vehicle modelsTwenty or thirty million facesUbiquitous. In this case, you can contact our customers for consultationTian Yuan Enterprise EditionSpecifics. Tian Yuan Software Enterprise Edition is more powerful:
It supports offline deployment, can process files offline, has strong confidentiality, and is more friendly to many state-owned enterprises and large enterprises;
Support batch processing of files, you can process multiple files at one time at the same time, and individuals or enterprises with a lot of tasks and tight task time can have an in-depth understanding;
There is no limit to the uploaded model, including the model size, the number of model faces, the number of sub-objects, etc., all of which are unlimited and powerful.
Tianyuan software supports more than 60 3D model file formats。For specific formats, you can log in to the official website of Tian Yuan and click "Help Documents" - "Support Input Model Format" in the upper right corner of the home page, and you can see the supported model formats corresponding to each function.
