详细描述

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 代替。

enum QMesh:: Status

This enum identifies the status of shader used.

常量 描述
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
