Exploring the New Frontier in 3D Modeling: CRM vs. Rodin Gen 1 🗻

In one of my last article, we turn the spotlight on Rodin Gen 1. Today we have a new contender in the 3D modeling arena, the CRM (Convolutional Reconstruction Model) model. Promising to revolutionize how we create objects and beyond, CRM brings new techniques to the table, with UV texturing models.

CRM vs RODIN

Today's comparison utilizes a captivating image as our base reference for both CRM and Rodin Gen 1, setting the stage for an in-depth analysis.

Masked Image Challenges

For all models, the first task is to extract the "important" object in the image and remove the background. They use a Masking model to only keep the interesting part of the image.

First, CRM image masking :

A bit of difficulty with the tree.

Then, Rodin Image masking :

Geometry is bumped everywhere, yet texturing masks the chaos.

Despite initial messiness, Rodin's true power lies in its ability to maintain better geometry, especially evident in the face and body.

The Magic of Texturing

Texturing isn't just about aesthetic appeal; it's a strategic tool to create the illusion of smoother geometry. CRM leverages this to great effect, though sometimes at the cost of true geometric fidelity. In contrast, Rodin Gen 1 prioritizes accurate geometry, making it a reliable choice for projects where structural integrity trumps textural illusion.

Final Thoughts

The comparison between CRM and Rodin Gen 1 reveals a fascinating aspect of 3D modeling: the balance between texture and geometry. While CRM excels in hiding imperfections through sophisticated texturing, Rodin Gen 1 shines in preserving the original geometry, offering a clearer, more accurate depiction of the model.
