GLTEXTURE2DARRAY

GLTEXTURE2DARRAY is a texture target in OpenGL, introduced in version 3.0, that represents an array of 2D textures. Each layer in the array is a 2D texture, and all layers share the same width, height, and format. This allows for efficient storage and manipulation of multiple 2D textures as a single texture object, reducing the overhead associated with binding and managing multiple individual textures.

The primary advantage of GLTEXTURE2DARRAY is its ability to improve performance by reducing the number of texture bindings required. Instead of binding multiple 2D textures individually, a single GLTEXTURE2DARRAY can be bound, and the desired layer can be accessed using the texture coordinate's third component. This can lead to significant performance improvements, especially in applications that require frequent texture switching, such as particle systems or multi-layered rendering techniques.

GLTEXTURE2DARRAY supports various texture operations, including filtering, wrapping, and mipmapping. It can be used with both floating-point and integer formats, making it suitable for a wide range of applications, from standard color textures to more specialized uses like shadow maps or normal maps.

In summary, GLTEXTURE2DARRAY is a powerful and efficient texture target in OpenGL that allows for the storage and manipulation of multiple 2D textures as a single object. Its ability to reduce texture binding overhead and support for various texture operations makes it a valuable tool for modern graphics programming.
