public class OVRTextureLayoutOctilinear extends org.lwjgl.system.Struct<OVRTextureLayoutOctilinear> 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

    • OVRTextureLayoutOctilinear

      public OVRTextureLayoutOctilinear(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.
