C++ API
The C++ headers for ApertusVR are located in ApertusVR/common/include/ folder.
A C++ Plugin has to implement the IPlugin interface:
class IPlugin
{
public:
virtual void Init() = 0;
virtual void Run() = 0;
virtual void Step() = 0;
virtual void Stop() = 0;
virtual void Suspend() = 0;
virtual void Restart() = 0;
};
The constructor takes care of member initializations.
Ape::ApeTesterPlugin::ApeTesterPlugin()
{
mpSceneManager = Ape::ISceneManager::getSingletonPtr();
mpEventManager = Ape::IEventManager::getSingletonPtr();
mpEventManager->connectEvent(Ape::Event::Group::NODE, std::bind(&ApeTesterPlugin::eventCallBack, this, std::placeholders::_1));
mInterpolators = std::vector<std::unique_ptr<Ape::Interpolator>>();
mDemoObjectNode = Ape::NodeWeakPtr();
}
This method is for initializing geometries, nodes, etc. for your plugin. The following example uses Init() to create lights and the skybox:
void Ape::ApeTesterPlugin::createLights()
{
if (auto light = std::static_pointer_cast<Ape::ILight>(mpScene->createEntity("light1", Ape::Entity::LIGHT).lock()))
{
light->setLightType(Ape::Light::Type::DIRECTIONAL);
light->setLightDirection(Ape::Vector3(0, -1, -1));
light->setDiffuseColor(Ape::Color(0.35f, 0.35f, 0.35f));
light->setSpecularColor(Ape::Color(0.35f, 0.35f, 0.35f));
}
if (auto light = std::static_pointer_cast<Ape::ILight>(mpScene->createEntity("light2", Ape::Entity::LIGHT).lock()))
{
light->setLightType(Ape::Light::Type::DIRECTIONAL);
light->setLightDirection(Ape::Vector3(0, -1, 1));
light->setDiffuseColor(Ape::Color(0.35f, 0.35f, 0.35f));
light->setSpecularColor(Ape::Color(0.35f, 0.35f, 0.35f));
}
}
void Ape::ApeTesterPlugin::createSkyBox()
{
if (auto skyBoxMaterial = std::static_pointer_cast<Ape::IFileMaterial>(mpScene->createEntity("skyBox", Ape::Entity::MATERIAL_FILE).lock()))
{
skyBoxMaterial->setFileName("skyBox.material");
skyBoxMaterial->setAsSkyBox();
}
}
void Ape::ApeTesterPlugin::Init()
{
createSkyBox();
createLights();
}
The Run() method can be used to implement loops until the Stop of the plugin. It is the place where animations, and other interactions can be used.
void Ape::ApeTesterPlugin::Run()
{
while (true)
{
if (!mInterpolators.empty())
{
for (std::vector<std::unique_ptr<Ape::Interpolator>>::iterator it = mInterpolators.begin(); it != mInterpolators.end();)
{
(*it)->iterateTopSection();
if ((*it)->isQueueEmpty())
it = mInterpolators.erase(it);
else
it++;
}
}
std::this_thread::sleep_for(std::chrono::milliseconds(40));
}
}
