public class XrTriangleMeshCreateInfoFB extends org.lwjgl.system.Struct<XrTriangleMeshCreateInfoFB> implements org.lwjgl.system.NativeResource
The information to create a triangle mesh.
Description

Mesh buffers can be updated between TriangleMeshBeginUpdateFB and TriangleMeshEndUpdateFB calls.

If the mesh is non-mutable, vertexBuffer must be a pointer to an array of vertexCount XrVector3f structures. If the mesh is non-mutable, indexBuffer must be a pointer to an array of 3 * triangleCount uint32_t vertex indices.

    • XrTriangleMeshCreateInfoFB

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

    • 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.

    • flags

      public long flags()
      a bitmask of XrTriangleMeshFlagBitsFB that specify behavior.

    • windingOrder

      public int windingOrder()

    • vertexCount

      public int vertexCount()
      the number of vertices in the mesh. In the case of the mutable mesh, the value is treated as the maximum number of vertices the mesh will be able to represent at any time in its lifecycle. The actual number of vertices can vary and is defined when TriangleMeshEndUpdateFB is called.

    • vertexBuffer

      public @Nullable XrVector3f vertexBuffer()
      a pointer to the vertex data. The size of the array must be vertexCount elements. When the mesh is mutable (({@code flags} &amp; {@link FBTriangleMesh#XR_TRIANGLE_MESH_MUTABLE_BIT_FB TRIANGLE_MESH_MUTABLE_BIT_FB}) != 0), the vertexBuffer parameter must be NULL and mesh data must be populated separately.

    • triangleCount

      public int triangleCount()
      the number of triangles in the mesh. In the case of the mutable mesh, the value is treated as the maximum number of triangles the mesh will be able to represent at any time in its lifecycle. The actual number of triangles can vary and is defined when TriangleMeshEndUpdateFB is called.

    • indexBuffer

      public @Nullable IntBuffer indexBuffer(int capacity)
      Parameters:
      capacity - the number of elements in the returned buffer
      Returns:
      the triangle indices. The size of the array must be triangleCount elements. When the mesh is mutable (({@code flags} &amp; {@link FBTriangleMesh#XR_TRIANGLE_MESH_MUTABLE_BIT_FB TRIANGLE_MESH_MUTABLE_BIT_FB}) != 0), the indexBuffer parameter must be NULL and mesh data must be populated separately.
