Description

Class for handling 2D texture arrays.

Modern graphics APIs (e.g. D3D10 and later, OpenGL ES 3.0 and later, Metal etc.) support "texture arrays", which is an array of same size & format textures. From the shader side, they are treated as a single resource, and sampling them needs an extra coordinate that indicates which array element to sample from.

Typically texture arrays are useful as an alternative for texture atlases, or in other cases where objects use a set of same-sized textures (e.g. terrains).

Currently in Unity texture arrays do not have an import pipeline for them, and must be created from code, either at runtime or in editor scripts. Using Graphics.CopyTexture is useful for fast copying of pixel data from regular 2D textures into elements of a texture array. From editor scripts, a common way of creating serialized texture array is to create it, fill with data (either via Graphics.CopyTexture from regular 2D textures, or via SetPixels or SetPixels32) and save it as an asset via AssetDatabase.CreateAsset.

Note that not all platforms and GPUs support texture arrays; for example Direct3D9 and OpenGL ES 2.0 do not. Use SystemInfo.supports2DArrayTextures to check.

ToStringReturns the name of the GameObject.
GetNativeTexturePtrRetrieve a native (underlying graphics API) pointer to the texture resource.

Static Functions

DestroyУдаляет GameObject, Component или Asset.

FindObjectOfTypeReturns the first active loaded object of Type type.
FindObjectsOfTypeReturns a list of all active loaded objects of Type type.
InstantiateClones the object original and returns the clone.
SetGlobalAnisotropicFilteringLimitsSets Anisotropic limits.

Operators

boolDoes the object exist?
operator !=Compares if two objects refer to a different object.
operator ==Compares two object references to see if they refer to the same object.
