Class OESTextureView

java.lang.Object

org.lwjgl.opengles.OESTextureView

public class OESTextureView
extends Object

Native bindings to the OES_texture_view extension.

This extension allows a texture's data store to be "viewed" in multiple ways, either reinterpreting the data format/type as a different format/ type with the same element size, or by clamping the mipmap level range or array slice range.

The goals of this extension are to avoid having these alternate views become shared mutable containers of shared mutable objects, and to add the views to the API in a minimally invasive way.

No new object types are added. Conceptually, a texture object is split into the following parts:

• A data store holding texel data.
• State describing which portions of the data store to use, and how to interpret the data elements.
• An embedded sampler object.
• Various other texture parameters.

With this extension, multiple textures can share a data store and have different state describing which portions of the data store to use and how to interpret the data elements. The data store is refcounted and not destroyed until the last texture sharing it is deleted.

This extension leverages the concept of an "immutable texture". Views can only be created of textures created with TexStorage*.

Requires GLES 3.1.
