How to browse the data of super-large 3D model quickly?

Facing the huge data engineering and the complex and diverse needs of Party A, an easy-to-use real-life 3D browser should not only be convenient for browsing, but also support the early data checking. For the front-end data processors in the industry, choosing a handy real-life 3D browser will undoubtedly get a more efficient work experience.

A free 3D model browser for real scenes.

DasViewer is an open and lightweight 3D model browser independently developed by General Trend Wisdom. You can use it for free without plug-ins.

DasViewer can quickly load and display 3D data of large-scale oblique photography. In addition to the basic labeling and measuring functions, it also has more practical analysis functions, which is helpful for users to integrate and edit data later.

quick response

Open the model with one click.

DasViewer provides users with a variety of convenient ways to open 3D models, which can open tile models in osgb format, without manually creating data indexes, and also supports obj data display. It has convenient data set management function, supports multi-channel opening mode, and can integrate and open model data with one click without copying data to the same folder in the face of block work of super-large-scale real-life three-dimensional data items with hundreds of GB or even TB levels.

Open the model quickly without complicated operation.

Conform to reality

Assist people in the industry to operate conveniently.

DasViewer contains a comprehensive set of tools, and its rich and practical functions can complete various tasks, providing more refined and intelligent display, labeling and analysis functions for 3D real-life maps.

1. Unique professional function and convenient use.

In the initial stage of model making, the range line function can better support KML application, quickly select tiles and check the target range to check data integrity. At the same time, in the actual production process of data, there is often a lack of accuracy, which leads to error accumulation. The accuracy check function can directly display errors and generate accuracy reports as needed. DasViewer simplifies the process of manual measurement, marking and inspection into an automatic tool, which can directly check the accuracy of data. Compared with the previous operation mode, the cumbersome procedures are greatly reduced. Model measurement and labeling function can quickly measure key information such as coordinates, distance and area of the target object, and provide data support for further analysis and decision-making. It is worth mentioning that the marking function can not only provide the timeliness and intuitive marking of the target building, but also link the template software. In the template, you can directly find the corresponding position through the marking point to repair the template, effectively reducing the cost of work communication.

Visual display of measurement results

The accuracy check function can automatically generate reports.

Support direct import of KML series products.

2. It has its own lighting effect adjustment to optimize the model effect.

The background and light source adjustment function can solve the problem of darkening or overexposure caused by weather in the actual data acquisition process by adjusting the brightness of the model. It is not only suitable for tilt model, but also suitable for small object model of cultural relics and consumption level. This function is also very friendly. Under the adjustment of background color and light source, the brightness of different viewing angles will change, making the model look layered and produce vivid effects.

Adjust the problem of overexposure or darkening of the real 3D model.

3. Diversified results show that it is simple and easy to use.

The route roaming function can freely control the browsing route, feel the layout of buildings and roads, set up a customized flight tour of the roaming route, output high-definition video according to the flight route, and achieve a clear and smooth model display effect. At the same time, select the resolution to output high-definition maps without the help of third-party software.

With the help of third-party software, it is easy to get stuck and the model loading is fuzzy.

Roaming function can record and export video directly, which is smoother and clearer.

At present, DasViewer has added dual-screen function, which can directly compare data. In the future, it will realize the linkage with more full-process products of the general trend real-life 3D service, help users fully tap the data potential, and provide strong support for industry applications.
