1. Characteristics of 3D digital modeling of cultural relics
Cultural relics have been buried underground for thousands of years. Due to the passage of time, natural destruction and human factors, many cultural relics have been lost or lost. As a result, every artifact that was preserved became extremely valuable and scarce. In order to digitally restore the original appearance of cultural relics, it is necessary to use professional scanners and modeling software to achieve high-precision scanning and modeling of cultural relics.
Digital restoration of cultural relics means that the cultural relic model needs to accurately restore the form and details of the cultural relics, including texture, color, size, etc. The total amount requires a powerful material texture mapping tool. This article will explain how to use it Restore the cultural relic model. GLTF Editor-NSDT
2. The significance of 3D digital modeling of cultural relics
Cultural relic 3D modeling is a process of converting valuable cultural relics such as cultural heritage, artworks or historical relics into digital three-dimensional models. The following are several characteristics of 3D modeling of cultural relics:
Protection and preservation: Through 3D modeling of cultural relics, digital preservation and protection of cultural relics can be achieved. Cultural relics may be affected by factors such as natural destruction, climate change, man-made damage, etc., and digital modeling can ensure that their original form is recorded and provides easy access for future generations.
Visualization and display: 3D modeling of cultural relics enables cultural relics to be displayed in a virtual environment in a realistic and accurate manner. This allows people to appreciate and understand the characteristics and value of artifacts without having to travel to an actual museum or site.
Research and education: Through digital modeling of cultural relics, academics and researchers can conduct more in-depth analysis and research. At the same time, this also provides educational institutions with a wealth of teaching materials and learning resources, allowing students to learn and understand history and culture more intuitively.
Communication across time and space: 3D modeling of cultural relics breaks the limitations of time and space. People can share and exchange cultural relic models through the Internet or other digital platforms, promoting cross-regional and cross-border cultural exchanges.
Virtual reconstruction and restoration: For cultural relics that have been damaged or partially destroyed, 3D modeling can realize their reproduction through virtual reconstruction and restoration. This is of great significance for restoring the original appearance of history and retaining the complete form of cultural relics.
In general, 3D modeling of cultural relics combines the advantages of technology, cultural heritage protection and academic research, allowing precious cultural relics to be protected, inherited and extended in digital form.
3. How to digitally restore cultural relic models
GLTF Editor-NSDT As an online material and texture editing tool, it is developed based on Three.js and can be run in any browser that supports webGL. There is no need to install or download additional Plug-ins or dependencies can be used by opening the browser.
Open the GLTF editor in the browser and import the model into the editor. If the model itself has materials, the material information of the model will be read and displayed in the right panel of the software. The material panel information on the right supports editing of materials. and modifications, as shown below:
Closer to home, let’s first import the 3D model without material texture mapping:
Select the material bar in the material panel on the right, select the type of map you want to set, click the file selection box after the map, and select the local material map to upload. After the map is uploaded, the system will automatically calculate the UV and perfectly map the texture map to 3D On the model, as shown below:
Note: Texture files can be created using image editing tools or by finding some online resources.
GLTF Editor-NSDT Not only can you set the texture map of the 3D model, you can also set the geometric origin of the model and merge meshes with the same material attributes to achieve lightweight models. , is a rare and practical online model editing tool.
