Texel
A Texel, texture element, or texture pixel is the fundamental unit of a texture map. Texture maps are used to add detail and realism to 3D objects. They are made up of a grid of texels, each of which stores color information.
When a 3D object is rendered, the texels that correspond to the surface of the object are used to calculate the color of each pixel on the screen. This process is called texture mapping.
Texels can be of any size, but they are typically square. The size of the texels affects the level of detail that can be achieved. Larger texels result in lower detail, while smaller texels result in higher detail.
Here are some of the benefits of using texels in computer graphics:
- They can be used to add detail and realism to 3D objects.
- They can be used to create a variety of textures, such as wood, stone, and metal.
- They can be used to create animated textures, such as water and fire.
- They are relatively easy to create and manage.
Here are some of the drawbacks of using texels in computer graphics:
- They can increase the file size of a 3D object.
- They can require more processing power to render.
- They can be difficult to create for complex objects.
Overall, texels are a powerful tool that can be used to add detail and realism to 3D objects. They are relatively easy to create and manage, but they can increase the file size of a 3D object and require more processing power to render.
