3D data optimization, explained

Learn the importance of 3D data optimization for real-time 3D, plus best practices, use cases, and what you need to get started.

The importance of 3d data optimization

In the dynamic worlds of manufacturing, architecture, and engineering, the importance of accurate and efficient data handling cannot be overstated. 3D data, with its complex structures and vast volumes, can pose significant challenges in terms of storage, processing, and visualization. However, the advent of 3D data optimization has transformed these industries, opening up new avenues for innovation and excellence.

Optimization reduces the file size of 3D models by optimizing geometry and textures, leading to faster loading and processing. In augmented reality (AR) contexts, it eliminates lag, ensuring a seamless experience. It also reduces latency for mobile Web 3D in model data transmission, improving performance and user experience.

Best practices

3D data optimization aims to reduce the complexity of 3D data while maintaining the highest level of detail possible. This involves processes such as:

Polygon reduction: Minimizes the number of polygons in a model without significantly compromising quality.

Texture mapping: Allows for the application of high-resolution details onto a low-poly model through a 2D image. This not only saves computing resources but also accelerates rendering times, a critical factor in industries like gaming and entertainment.

Level of detail (LOD): Different complexities of a model are used depending on the viewing distance. More detailed versions are used for close-up views, while simpler versions are swapped in as the viewer’s distance increases. This allows for significant savings in rendering time and resources, leading to smoother performance, particularly in real-time applications. 

Caching and data streaming: Caching enables faster access to frequently used data. Data streaming makes it possible to have more detailed models without having to wait for a full download. This combination of techniques is often essential in meeting the performance demands of modern 3D applications.

Collaborative workflows: With the growing complexity and size of 3D data, having multiple people working together on a project can reduce development time and cost. It is important to have an efficient file-sharing workflow in place, including a centralized system for storing files and tracking changes, as well as reliable team member access to current project data.
