Class OVRTextureLayoutOctilinear

  • All Implemented Interfaces:
    java.lang.AutoCloseable, org.lwjgl.system.NativeResource, org.lwjgl.system.Pointer
    public class OVRTextureLayoutOctilinear
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
    Multiresolution descriptor for Octilinear.

    Usage of this layer must be successfully enabled via EnableExtension before it can be used.

    Size of W quadrants:

    
 SizeLeft + SizeRight <= Viewport.Size.w
 SizeUp   + sizeDown  <= Viewport.Size.h
 
 Clip space (0,0) is located at Viewport.Pos + (SizeLeft,SizeUp) where
 Viewport is given in the layer description.

 For example, when rendering quadrant 0 its scissor rectangle will be
 
  Top    = 0
  Left   = 0
  Right  = SizeLeft
  Bottom = SizeUp
 
 and the scissor rectangle for quadrant 1 will be:
 
  Top    = 0
  Left   = SizeLeft
  Right  = SizeLeft + SizeRight
  Bottom = SizeUp

    • Constructor Detail

      • OVRTextureLayoutOctilinear

        public OVRTextureLayoutOctilinear​(java.nio.ByteBuffer container)
        Creates a OVRTextureLayoutOctilinear instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

        The created instance holds a strong reference to the container object.
