Class HiddenAreaMesh

  • All Implemented Interfaces:
    java.lang.AutoCloseable, NativeResource, Pointer

    public class HiddenAreaMesh
    extends Struct
    implements NativeResource
    The mesh to draw into the stencil (or depth) buffer to perform early stencil (or depth) kills of pixels that will never appear on the HMD. This mesh draws on all the pixels that will be hidden after distortion.

    If the HMD does not provide a visible area mesh pVertexData will be NULL and unTriangleCount will be 0.

     struct HiddenAreaMesh_t {
         HmdVector2_t * pVertexData;
         uint32_t unTriangleCount;
     }
    • Field Detail

      • SIZEOF

        The struct size in bytes.
      • ALIGNOF

        The struct alignment in bytes.
      • PVERTEXDATA, UNTRIANGLECOUNT

    • Constructor Detail

      • HiddenAreaMesh

        public HiddenAreaMesh​(java.nio.ByteBuffer container)
        Creates a HiddenAreaMesh 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.

      • sizeof

        public int sizeof()
        Description copied from class: Struct
        Returns sizeof(struct).
        Specified by:
        sizeof in class Struct
      • unTriangleCount

        public int unTriangleCount()
        Returns the value of the unTriangleCount field.
      • malloc

        public static HiddenAreaMesh malloc()
        Returns a new HiddenAreaMesh instance allocated with memAlloc. The instance must be explicitly freed.
      • calloc

        public static HiddenAreaMesh calloc()
        Returns a new HiddenAreaMesh instance allocated with memCalloc. The instance must be explicitly freed.
      • create

        public static HiddenAreaMesh create​(long address)
        Returns a new HiddenAreaMesh instance for the specified memory address.
      • createSafe

        @Nullable
        public static HiddenAreaMesh createSafe​(long address)
        Like create, but returns null if address is NULL.
      • create

        public static HiddenAreaMesh.Buffer create​(long address,
                                                   int capacity)
        Create a HiddenAreaMesh.Buffer instance at the specified memory.
        Parameters:
        address - the memory address
        capacity - the buffer capacity
      • createSafe

        @Nullable
        public static HiddenAreaMesh.Buffer createSafe​(long address,
                                                       int capacity)
        Like create, but returns null if address is NULL.
      • mallocStack

        public static HiddenAreaMesh mallocStack()
        Returns a new HiddenAreaMesh instance allocated on the thread-local MemoryStack.
      • callocStack

        public static HiddenAreaMesh callocStack()
        Returns a new HiddenAreaMesh instance allocated on the thread-local MemoryStack and initializes all its bits to zero.
      • mallocStack

        public static HiddenAreaMesh mallocStack​(MemoryStack stack)
        Returns a new HiddenAreaMesh instance allocated on the specified MemoryStack.
        Parameters:
        stack - the stack from which to allocate
      • callocStack

        public static HiddenAreaMesh callocStack​(MemoryStack stack)
        Returns a new HiddenAreaMesh instance allocated on the specified MemoryStack and initializes all its bits to zero.
        Parameters:
        stack - the stack from which to allocate
      • nunTriangleCount

        public static int nunTriangleCount​(long struct)
        Unsafe version of unTriangleCount().
