UVkoordinátáinak

UVkoordinátáinak refers to the UV coordinates of a given object or surface within a 3D graphics pipeline. These coordinates are a two-dimensional mapping used to define how a texture image is applied to the surface of a 3D model. The 'U' component typically represents the horizontal axis of the texture, and the 'V' component represents the vertical axis.

When a 3D model is created, its vertices are assigned not only spatial (X, Y, Z) coordinates but also UV coordinates. These UV coordinates dictate which part of a 2D texture image will be projected onto each point of the 3D surface. For instance, a vertex on a cube's face might be assigned UV coordinates of (0,0) to represent the bottom-left corner of the texture, while another vertex on the same face might have UV coordinates of (1,1) to represent the top-right corner. By interpolating these UV values across the surface of a polygon, the graphics system can determine the correct texel (texture pixel) to sample for each pixel being rendered on the screen.

The process of assigning UV coordinates is called UV unwrapping or UV mapping. This is crucial for texturing, as it allows artists to control precisely how textures wrap around complex shapes without distortion. Improper UV mapping can lead to stretched, squashed, or misaligned textures, significantly impacting the visual quality of the 3D model. UVkoordinátáinak are therefore a fundamental concept in 3D texturing and rendering.
