[−][src]Struct qt_3d_render::QBuffer

#[repr(C)]pub struct QBuffer { /* fields omitted */ }

Provides a data store for raw data to later be used as vertices or uniforms.

C++ class: Qt3DRender::QBuffer.

C++ documentation:

Provides a data store for raw data to later be used as vertices or uniforms.

Data can either be provided directly using QBuffer::setData() or by specifying a generator with QBuffer::setDataGenerator() and providing a Qt3DRender::QBufferDataGeneratorPtr.

When using a generator the data will be loaded asynchronously in a job. The loaded data can be read back if the QBuffer::syncData flag is set to true.
