public class XrFaceExpressionInfo2FB extends org.lwjgl.system.Struct<XrFaceExpressionInfo2FB> implements org.lwjgl.system.NativeResource
Describes the information to obtain facial expression.
Description

The XrFaceExpressionInfo2FB structure describes the information to obtain facial expression. The application should pass a time equal to the predicted display time for the rendered frame. The system must employ appropriate modeling to provide expressions for this time.

  • Constructor Details

    • XrFaceExpressionInfo2FB

      public XrFaceExpressionInfo2FB(ByteBuffer container)
      Creates a XrFaceExpressionInfo2FB 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<XrFaceExpressionInfo2FB>

      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.

    • time

      public long time()
      an XrTime at which the facial expression weights are requested.

    • type

      public XrFaceExpressionInfo2FB type(int value)
      Sets the specified value to the type() field.

    • type$Default

      public XrFaceExpressionInfo2FB type$Default()
      Sets the TYPE_FACE_EXPRESSION_INFO2_FB value to the type() field.

    • next

      public XrFaceExpressionInfo2FB next(long value)
      Sets the specified value to the next() field.

    • time

      public XrFaceExpressionInfo2FB time(long value)
      Sets the specified value to the time() field.

    • set

      public XrFaceExpressionInfo2FB set(int type, long next, long time)
      Initializes this struct with the specified values.

    • set

      public XrFaceExpressionInfo2FB set(XrFaceExpressionInfo2FB src)
      Copies the specified struct data to this struct.
      Parameters:
      src - the source struct
      Returns:
