In 3D modeling, one critical aspect differentiating various 3D models is the polygon count. The number of polygons determines how detailed and visually appealing a model can be. Higher polygon counts lead to more detailed and intricate models, whereas lower polygon counts result in simpler, more manageable designs.

Different industries require different levels of detail in 3D models, which gives rise to high poly and low poly modeling. The number of polygons defines these two approaches to 3D modeling, how they are used, and the rendering processes involved.

In this article, we’ll explore the definitions of high poly and low poly models, compare their differences, and highlight the contexts in which they are most commonly applied. Ready to dive in?

 

What is a High Poly Model?

A high poly model is a 3D object with a significant number of polygons arranged in a mesh to achieve intricate and fine details. The term “high poly” refers to the large polygon count, which allows for more detailed geometry that can be manipulated to form complex shapes.

High Poly vs Low Poly Modeling

Let’s examine the key differences between high-poly and low-poly models in terms of detail, ease of use, rendering, and texturing.

 

1. Level of Detail

The most apparent difference between high poly and low poly models is the level of detail. High poly models are highly detailed and often used for realistic visual representations, whereas low poly models have fewer details due to the reduced polygon count. Low poly models typically appear smoother and less textured, but they can still maintain a visually appealing look with the right techniques.

 

2. Ease of Use

Working with high poly models can be challenging due to the heavy computational load. They take longer to load, view, and edit, which can slow down the modeling process. Creating or editing a high poly model can become especially cumbersome if you’re using outdated hardware.

In contrast, low poly models are much easier to manipulate and work with. They require less processing power, making the development process faster and more efficient. This is particularly important when working with real-time rendering applications like games or virtual reality.

 

3. Rendering Time

The time it takes to render can differ significantly based on the model’s complexity. Due to their complexity, high poly models take much longer to render, often requiring hours or even days to render fully, especially when aiming for photorealism.

Conversely, low poly models render much faster, making them ideal for real-time applications like gaming, augmented reality, and virtual reality, where rendering speed is critical.

 

4. Texturing

The number of polygons isn’t the only factor that defines a model’s complexity. Texturing also plays a significant role. High poly models allow for more detailed and varied texture maps, which can add further realism to the model.

However, the texturing process must be more efficient for low poly models. Techniques like normal maps or baked textures are often used to simulate details without adding more polygons. This helps maintain performance while still achieving visually pleasing results.

  • 3D Gaming

The gaming industry is perhaps the most prominent user of low poly models. While many modern games feature highly detailed environments and characters, low poly models are often used for secondary characters, background elements, or mobile games, where fast rendering and performance are critical.

 

How to Make Low Poly look like High Poly?

Here are some strategies to enhance the details of a 3D model while keeping the polygon count low.

Tip 1:

Incorporate normal and height maps to influence how light interacts with the object in your render. This technique creates the illusion of intricate details. Additionally, you can use diffuse maps to introduce color variations.

Tip 2:

Avoid using textures larger than 4096×4096 or merging too many maps into a single texture sheet, as this can compromise your model’s effectiveness.

Tip 3:

Start by creating a low poly base mesh, then duplicate it and apply high poly details. Utilize software such as Adobe Substance Painter to bake the details from the high poly mesh. Finally, overlay this baked detail onto the low poly mesh as a normal map.

 

High Poly vs Low Poly: Which Should You Choose?

Deciding between high poly and low poly 3D modeling techniques depends on your project’s goals.

  • Choose High Poly for Detail: High poly models are the way to go if you’re aiming for maximum detail, especially in CG imagery or animation. The greater the number of polygons, the more visually rich the result will be. High poly modeling is perfect for projects that require photorealism or precise cross-section visualizations.

  • Choose Low Poly for Speed: Low poly modeling is more efficient when speed is your priority, such as in gaming or interactive applications like AR and VR. With fewer polygons, models load faster and run more smoothly. You can enhance the appearance of low poly models using techniques like normal maps to add depth without increasing the polygon count.

Both high poly and low poly modeling techniques have their place in 3D design, and mastering both will give you flexibility across various projects. While low poly modeling may be easier to begin with, a thorough understanding of both methods will enable you to create 3D models that meet the specific needs of each industry.
