How does subdividing affect the detail of 3D models?

Subdividing a 3D model increases the level of detail by creating additional geometry. When a model is subdivided, it effectively divides the existing polygons into smaller ones, which increases the vertex count and allows for more complex shapes. This process results in smoother surfaces and finer details, enabling artists to add intricate features and subtle variations to the model’s surface.

By increasing the polygon count through subdivision, the model can better capture organic shapes and gradients, which are crucial for achieving realism in 3D graphics. Additionally, this enhanced detail can improve the appearance when textures are applied, as the increased geometry provides a more nuanced surface for the textures to adhere to, thus improving the visual fidelity of the final render.

The other options describe effects that do not align with the purpose of subdivision. Reducing detail or having no effect directly contradicts the nature of what subdivision aims to achieve, while suggesting it only affects textures ignores the fundamental changes made to the model’s geometry.
