How to develop data excuses for 3D models

In fact, to realize the rapid development of 3D models, we only need to "treat the symptoms" in three steps, as follows:

The first step is to turn to a common format.

As long as the 3D model format is converted into a file format that can be quickly opened on a web page, the limitation that the model file can only be opened in a specific software can be solved. But the problem is that there are more than 400 model formats in the market, and now the general company only supports the conversion from several to 10, which is not enough.

Therefore, in order to break this technical bottleneck, a powerful 3D model format conversion tool is developed.

Now there are more than 60 model formats that can be automatically converted into international standard formats. At the same time, it supports the conversion to the general format AMRT of Laozi cloud, which fundamentally solves the cross-platform display problem of the model.

Step 2: Fully automatic lightweight

We have solved the multi-platform compatibility problem of the model, and then we will deal with the problem that it is difficult to load the device display because of the large model. Since the model is large, make it smaller. However, you must not be stupid enough to manually compress and shrink the surfaces one by one, which is too inefficient. Now there are perfect lightweight tools to choose from.

Laozi cloud lightweight technology will not only automatically judge the model structure, but also generate the optimal compression result of reduced surface.

Subtraction face: 2,654.38+0.6 million faces, four sides+triangular faces.

After shrinking: 120000 triangles and it is fully automatic! With only one key operation, your big model can be quickly transformed into a small model. At the same time, the drawing accuracy, resolution, model size and key data information of the model are flexible and controllable.

For example, the lightweight BIM model can completely retain its component information, which is very convenient for subsequent development and application. Similarly, like the 3D oblique photography model in real life, it also supports automatic lightweight. In the past, several G models can be transformed into more than ten meters in just a few minutes.

Moreover, in the next version of Laoziyun's lightweight oblique photography, the overall performance and effect of model processing will be greatly improved, not only the real-time loading fluency can be improved, but also the model accuracy can be accurate to 2-3 cm, which fully guarantees the display effect.

Step 3: Network presentation

After the model is processed, it needs a very important technical support to show it to users: the display framework. Because the architecture of modeling software is different from the display hardware, the effect cannot be directly transplanted to the web, so we need to use a professional display framework to display and develop the model.

The 3D display framework developed by Laozi Cloud can not only restore the model effect, but also analyze the material effect of the original model and restore it as much as possible. At the same time, in order to meet the more personalized needs of customers, SDK is developed, so that customers can quickly follow up their own needs for display and business logic docking. So as to help users realize the smooth display and interaction of 3D models and application scenarios on the web.
