Declaration

struct winrt::Microsoft::Azure::ObjectAnchors::ObjectModel

Description

An object model exposes visual and geometrics information about a physical object to be detected, as well as parameters to determine how that object can be detected by the object observer.

Methods

Dispose

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

void Dispose();

GetTriangleIndices

Returns triangle indices on object model surface.

void GetTriangleIndices(winrt::array_view<uint32_t> indices);

Parameters

  • indices - Buffer to store triangle indices, allocated by the caller.

GetVertexNormals

Returns normals on object model surface in centered coordinate system.

void GetVertexNormals(winrt::array_view<Windows::Foundation::Numerics::float3> normals);

Parameters

  • normals - Buffer to store the normals, allocated by the caller.

GetVertexPositions

Returns vertices on object model surface in centered coordinate system.

void GetVertexPositions(winrt::array_view<Windows::Foundation::Numerics::float3> vertices);

Parameters

  • vertices - Buffer to store the vertexes, allocated by the caller.

LoadAsync

Load an object model from a byte array for offline inspection. Note that the returned model cannot be used to create an ObjectQuery, otherwise an will be thrown.

static Windows::Foundation::IAsyncOperation<::winrt::Microsoft::Azure::ObjectAnchors::ObjectModel> LoadAsync(winrt::array_view<unsigned char const> buffer);

Parameters

  • buffer - Byte array of an object model blob.

Returns

  • Windows::Foundation::IAsyncOperation<::winrt::Microsoft::Azure::ObjectAnchors::ObjectModel> - System.Threading.Tasks.Task`1.

Properties

BoundingBox

Bounding box aligned to object's principle axii, with size in meters.

winrt::Microsoft::Azure::ObjectAnchors::SpatialGraph::SpatialOrientedBox BoundingBox();

Id

Unique id of an object model.

winrt::guid Id();

OriginToCenterTransform

Transform from the model origin to centered coordinate system.

Windows::Foundation::Numerics::float4x4 OriginToCenterTransform();

TriangleIndexCount

Index list length of triangles on object model surface.

uint32_t TriangleIndexCount();

VertexCount

Number of vertices on object model surface.

uint32_t VertexCount();
