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.

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
