Class DefaultTextureBinder

  • All Implemented Interfaces:
    TextureBinder
    public final class DefaultTextureBinder
extends java.lang.Object
implements TextureBinder
    Class that you assign a range of texture units and binds textures for you within that range. It does some basic usage tracking to avoid unnecessary bind calls.

      int bind​(GLTexture texture)
      Binds the texture to an available unit.
      void end()
      Disables all used texture units and unbinds textures.
