3D style is a visual expression form built on 3D digital technology. Its core lies in simulating the three-dimensional forms and light-shadow relationships of the real world through the "length, width, and height" dimensions of virtual space, breaking the two-dimensional limitations of planar art.

Its realization relies on four core steps: modeling, texturing, lighting, and rendering. First, construct the geometric model of an object (such as the outline framework of a character or scene); then assign surface textures (such as the reflection of metal or the texture of fabric); next, set up virtual light sources to simulate real light and shadow (such as direct sunlight or indoor diffuse reflection); finally, generate images with a sense of spatial depth through rendering.

In terms of application scenarios, 3D style is widely used in fields such as film and television (e.g., character scenes in animated movies), games (interactive three-dimensional worlds), and design (3D renderings of products). It enables visual content to be more realistic, immersive, and interactive.
