AI Base Mesh Generator - Image to 3D

Introduction

In this article, I will share my experience experimenting with an AI tool called Rodin, designed to generate 3D models from images. Recently, as part of a project, I decided to test this AI-driven approach by using an image of a robot I had created in the past. The idea is to see how well AI can create a base mesh from a 2D image of a model I’ve already worked on.

Getting Started

To begin, I took a BPR (Best Preview Render) screenshot of the robot model I had developed. Next, I navigated to the Rodin website. For those interested, you can easily find it by searching "Rodin AI generator" on Google.

Once on the website, the process is straightforward: I uploaded my screenshot and initiated the generation process. The AI worked its magic and produced a 3D asset based on the uploaded image. While the results weren’t particularly impressive in terms of quality, the process demonstrated how the AI could potentially save time when designing something from scratch. It could serve as a useful starting point, especially if you need accurate proportions for a specific character or object.

Second Experiment: Creating a Cartoon Dragon

Encouraged by my initial test, I decided to try generating a new model. I opened Photoshop and created a 1024x1024 canvas, where I illustrated a cartoon dragon. After creating a few iterations, I settled on a design that I thought could work well for the AI generation.

After saving the image, I returned to the Rodin website to upload the dragon illustration. Once again, I clicked the generate button and awaited the AI's result. As I suspected, the output didn’t yield a usable final model, but it did provide a base mesh that had the correct proportions for the wings, head, and body.

Importing into ZBrush

Once I confirmed the generation, I downloaded the model file in OBJ format. I then imported the generated model into ZBrush. Although the initial state of the model was not ideal for immediate use—being higher poly than necessary—it still offered a better sculpting starting point than a basic sphere.

The generated model, while requiring further refinement and sculpting, presented well-defined shapes that helped establish the forms of the body and head of the dragon. Such a tool can potentially speed up workflow processes if used correctly, particularly for artists needing specific proportions.

Conclusion

Although the generated models from the AI might require additional sculpting and adjustments, the use of Rodin opens exciting possibilities for artists. It can help in creating base meshes that can streamline the modeling process and save time when working on bespoke designs.

Thank you for reading! I hope you found this exploration into AI-generated 3D models intriguing. See you in the next article!
