A context object intended for use with python's "with" syntax.
The WorldBlock class provides a simple means of ensuring that renderer->worldBegin() calls are matched by renderer->worldEnd() calls, even in the face of exceptions and multiple return statements from a function.
It calls renderer.worldBegin() in enter and renderer.worldEnd() in exit.
IECore::WorldBlock::WorldBlock | ( | RendererPtr | renderer, |
bool | active = true |
||
) |
Starts a new world block, calling renderer->worldBegin(). If active is false then nothing is done.
IECore::WorldBlock::~WorldBlock | ( | ) |
Closes the world block by calling renderer->worldEnd(). If active was false in the constructor then nothing is done.
