3D modeling is the process of creating digital representations of objects, characters, and environments for AR, VR, games, animation, and digital fashion. This is a crucial skill for anyone serious about working with 3D, as it affects the visual quality, performance, and interactivity of whatever it is that the artist will be creating. ‘‘In the case of our studio, we work in a style similar to the gaming industry for Augmented Reality. It is a small world with only a few skillful sculpting specialists,’’ says Rachid Van Der Veer, Co-Founder of Locus Solus Studio.
When we talk about High and Low Poly modeling, we're discussing the optimization and reduction of the polygon count of an individual 3D model. Understanding the differences between high and low-poly models is key to mastering 3D modeling and unlocking different use cases for both.
Static and Motion Usage
3D models are used in a wide array of applications, each of which benefits from different modeling techniques. High-poly models are ideal for creating static assets, detailed renders, or the initial draft of a design. These high-poly models boast rich details such as ambient occlusion, cavity, and normal maps, making them perfect for clients who need to review highly detailed previews before proceeding.
However, for interactive, real-time applications like 3D configurators, games, and AR/VR environments, low-poly models reign supreme. These models maintain a minimal polygon count, which allows them to be rendered quickly and smoothly in real-time engines without sacrificing too much quality. Low-poly modeling ensures a faster and more responsive experience, essential for dynamic environments.
The Complexity of the Geometry
One of the primary differences between high-poly and low-poly modeling lies in their geometric complexity. High-poly models are incredibly dense, made up of millions of polygons that allow for high levels of detail and smooth curvature.
This detailed geometry is perfect for static images and videos, where intricate design elements are needed.
Low-poly models, on the other hand, are simplified versions, built with significantly fewer polygons. To optimize these models for real-time applications, studios use a technique called retopology. This process involves manually reducing the polygon count by redrawing the object’s geometry to maintain its basic shape while making it easier to process for real-time rendering and animation.
“Our studio takes the time to hand-draw new polygon sets over the original high-poly model to ensure it can be rendered and animated in real-time,” Rachid explains. “This approach provides high-quality results while balancing performance.”
Details
With the advent of more powerful computers, high-poly models can incorporate extreme levels of detail. These models often include ornate designs, intricate surface details, and meticulous touches that are essential for close-up shots in film CGI or still renders. But while high-poly models can be stunning, they aren’t practical for real-time applications.
That’s where skilled artists come into play. In our studio, we go through a time-intensive process of optimizing high-poly models by hand. This ensures that every detail remains true to the original design, especially when it comes to organic characters where muscle flow, joints, and deformations must be considered for animation. The difference between an amateur and a professional lies in this careful attention to every tiny detail.
Texture Quality
Texture quality also varies between high-poly and low-poly models. For film and CGI, high-poly models require massive texture files that often demand significant processing power. In contrast, our low-poly models are carefully crafted to maintain a balance between quality and performance.
In our workflow, a skilled texture artist will "bake" the details of a high-poly model's textures into a more manageable, optimized texture for the low-poly version. By doing this, we preserve the visual fidelity of intricate textures and details, without burdening the rendering engine with excessively large files. This optimization allows our models to be lightweight and responsive while maintaining a high degree of realism—ideal for AR, gaming, and mixed-reality applications.
Conclusion
The distinction between high-poly and low-poly 3D modeling is about balancing detail and performance. High-poly models excel in static images, videos, and non-interactive applications, while low-poly models are crucial for real-time, interactive experiences in gaming and AR. Both techniques have their place, and mastering the ability to move between the two is a valuable skill in the world of 3D design.
At Locus Solus Studio, we strive to deliver the best of both worlds—leveraging high-poly detail where necessary while optimizing for low-poly performance to meet the demands of AR and VR. This dedication to excellence is what sets us apart in the competitive world of 3D modeling.
