Steps involved in creating 3D AR models

Apparently, any 3D modeler can create 3D visualizations for augmented reality. However, it requires a great level of technical expertise, a robust skillset, and an eye for detail. All the steps involved in the process require these three key things. Right from the initial conceptualization to the final execution, augmented reality 3D model creators must be adequately thorough with the nitty-gritty of AR technology. Below is our detailed guide to augmented reality modeling.

1. Conceptualization

   This is the first step towards creating a 3D design for augmented reality. Identify the purpose of the model, whether it is for marketing, product showcase, gaming, educational training, or any other application. Solidify your data with research by gathering reference materials and studying existing AR models.

   Skilled 3D artists create concept sketches or storyboards to further visualize the way the model will interact with the users.

2. Model creation

   At this stage, it is time to select high-end 3D modeling software and start creating the basic geometry of the model. Extruding, sculpting, and manipulating the vertices and edges come first, followed by developing the polygonal mesh. This will slowly give the model its structure.

   Alternatively, one can use the photogrammetry technique to scan 3D from 2D photos and then create the models. Once the model is done, enhance its appearance and realism with natural-looking textures and materials. You may also standardize reusable elements such as animations, textures, and colors for consistent performance.

3. Optimization

   This step is one of the most important while developing AR-ready 3D assets. Here, the 3D-generated model is further optimized by adjusting the polygon count and geometry. This is mainly done to improve the model’s performance and efficiency in AR applications.

   For better texture optimization and file reduction, optimize UV mapping, compress textures, and incorporate texture atlases. Doing this also improves rendering speed. Experienced 3D AR modelers usually create multiple versions of the model with varying levels of detail for A/B testing. This ensures optimal performance at different viewing distances and devices.

4. AR development

   Once you reach this step, it’s time for AR development, platform selection, adding triggers and interactions, and so on. You may select a high-end AR development platform for the purpose based on the target devices, as well as the model’s features.

   Import the digital model into the AR software and set up the environment with AR tracking elements, cameras, lighting, etc. Integrate triggers and interactions like swipe, pinch, tap, or control gestures using images or markers. At this stage, you may also add audio or video multimedia to add dimension to the model. The file can be played back when a user taps on a specific part of the model. Doing this greatly enhances the user experience.

   Finally, integrate the AR-optimized model into the real-world environment using image recognition and spatial mapping for placement accuracy.

5. Testing and iteration

   Now comes the step where two types of testing, namely, device testing and user testing, are executed. These tests evaluate the seamless performance of the models as well as detect any room for improvement.

   Start by testing the model on different smartphones, AR wearables, tablets, WebAR, and the like, and check the compatibility and visual fidelity. A user testing period using the model’s alpha and beta versions must come after this in order to find bugs, usability problems, etc. Make necessary iterations and refinements based on user feedback to optimize the 3D AR asset further.

   This step is crucial and must be done before the final release. 3D experts in professional 3D modeling companies conduct thorough testing and iteration processes.

6. Deployment

   This is the step where you have to be ready for the release and deployment of the model. Start by optimizing the finalized asset with all interactions and enhancements. Package it with necessary scripts into a deployable format compatible with the targeted AR platforms or devices.

   Finally, distribute the model through AR marketplaces, app stores, or enterprise deployment platforms for better user access and seamless experience.

There you are! A comprehensive checklist of all the necessary steps involved in creating industry-standard AR-ready 3D assets. Follow the steps above, and start designing compelling, interactive AR models that enhance user engagement and deliver valuable experiences.
