A BaseThread is a classic Cinema 4D thread. BaseThread cannot be instantiated; for custom threads see C4DThread Manual .

Access

A BaseThread is either accessed through various utility functions or is given as an argument of an implemented function of a plugin class. Such a BaseThread argument defines the thread context of a function that is executed in a thread. The called function should stop if the given thread is stopped.

In a VideoPostData::Execute() function the thread is obtained from the given VideoPostStruct argument.
In a ObjectData::GetVirtualObjects() function the thread is obtained from the given HierarchyHelp argument.
In a ShaderData plugin the sampling thread is obtained from the given InitRenderStruct argument.
etc.

使用

这些 BaseThread properties can be accessed:

BaseThread::TestBreak() : Returns true if the thread encountered a break condition to stop processing.
BaseThread::IsRunning() : Returns true if the thread is running.
BaseThread::End() : Ends the thread.

// In the Execute() function of a VideoPostData plugin one must // check if the rendering process should be stopped.

RENDERRESULT Execute( BaseVideoPost * node, VideoPostStruct * vps) { // check if break BaseThread * const bt = vps-> thread ; if (bt && bt-> TestBreak ()) { return RENDERRESULT::OK ; }
