public class XrSpaceTriangleMeshMETA extends org.lwjgl.system.Struct<XrSpaceTriangleMeshMETA> implements org.lwjgl.system.NativeResource
Output parameter to the xrGetSpaceTriangleMeshMETA function.
Description

The XrSpaceTriangleMeshMETA structure can be used by the application to perform the two calls required to obtain a triangle mesh associated to a specified spatial entity.

The output values written in the indices array represent indices of vertices: Three consecutive elements represent a triangle with a counter-clockwise winding order.

    • XrSpaceTriangleMeshMETA

      public XrSpaceTriangleMeshMETA(ByteBuffer container)
      Creates a XrSpaceTriangleMeshMETA 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.

  • Method Details

    • sizeof

      public int sizeof()
      Specified by:
      sizeof in class org.lwjgl.system.Struct<XrSpaceTriangleMeshMETA>

    • type

      public int type()
      the XrStructureType of this structure.

    • next

      public long next()
      NULL or a pointer to the next structure in a structure chain. No such structures are defined in core OpenXR or this extension.

    • vertexCapacityInput

      public int vertexCapacityInput()
      an input parameter for the application to specify the capacity of the vertices array, or 0 to indicate a request to retrieve the required capacity.

    • vertexCountOutput

      public int vertexCountOutput()
      an output parameter that will hold the number of vertices written in the output array, or the required capacity in the case that vertexCapacityInput is insufficient. The returned value must be equal to or larger than 3.

    • vertices

      public @Nullable XrVector3f.Buffer vertices()
      a pointer to an array of XrVector3f, but can be NULL if vertexCapacityInput is 0. The vertices are defined in the coordinate frame of XrSpace to which this struct is associated.

    • indexCapacityInput

      public int indexCapacityInput()
      an input parameter for the application to specify the capacity of the indices array, or 0 to indicate a request to retrieve the required capacity.

    • indexCountOutput

      public int indexCountOutput()
      an output parameter that will hold the number of indices written in the output array, or the required capacity in the case that indexCapacityInput is insufficient. The returned value must be a multiple of 3.

    • indices

      public @Nullable IntBuffer indices()
      a pointer to an array of uint32_t, but can be NULL if indexCapacityInput is 0. Each element refers to a vertex in vertices.

    • type$Default

      public XrSpaceTriangleMeshMETA type$Default()
      Sets the TYPE_SPACE_TRIANGLE_MESH_META value to the type() field.

    • next

      public XrSpaceTriangleMeshMETA next(long value)
      Sets the specified value to the next() field.

    • set

      public XrSpaceTriangleMeshMETA set(int type, long next)
      Initializes this struct with the specified values.

    • set

      public XrSpaceTriangleMeshMETA set(XrSpaceTriangleMeshMETA src)
