Qt3DRender::QMesh::Status | status() const

## Public Slots

void | setMeshName(const QString &meshName)

void | statusChanged(Qt3DRender::QMesh::Status status)

## Detailed Description

Loads mesh data from external files in a variety of formats. Qt3DRender::QMesh loads data into a single mesh.

In Qt3D 5.9, QMesh supports the following formats:

- Wavefront OBJ
- Stanford Triangle Format PLY
- STL (STereoLithography)

QMesh will also support the following format if the SDK is installed and the fbx geometry loader plugin is built and found:

- Autodesk FBX

If you wish to load an entire scene made of several objects, you should rather use the Qt3DRender::QSceneLoader instead.

## Member Type Documentation

### enum QMesh::Status

This enum identifies the status of shader used.

Constant | Value | Description
--- | --- | ---
`Qt3DRender::QMesh::None` | `0` | A source mesh hasn't been assigned a source yet
`Qt3DRender::QMesh::Loading` | `1` | The mesh geometry is loading
`Qt3DRender::QMesh::Ready` | `2` | The mesh geometry was successfully loaded
`Qt3DRender::QMesh::Error` | `3` | An error occurred while loading the mesh

## Property Documentation

### meshName : QString

Holds the name of the mesh.

Access functions:

QString | meshName() const
void | setMeshName(const QString &meshName)

Notifier signal:

void | meshNameChanged(const QString &meshName)

### source : QUrl

Holds the source url to the file containing the custom mesh.

Access functions:

QUrl | source() const
void | setSource(const QUrl &source)

Notifier signal:

void | sourceChanged(const QUrl &source)

### `[read-only]` status : const Status

Holds the status of the mesh loading.

Access functions:

Qt3DRender::QMesh::Status | status() const

Notifier signal:

void | statusChanged(Qt3DRender::QMesh::Status status)

See also Qt3DRender::QMesh::Status.

## Member Function Documentation

### `[explicit]` QMesh::QMesh(Qt3DCore::QNode *parent = nullptr)

Constructs a new QMesh with parent.
