Taking a Screenshot

Taking a screenshot involves three short steps:

1. Retrieve Camera to Capture

    auto camera = OcularCameras->getMainCamera();
   

2. Refresh the Camera's Render Texture

    auto renderTexture = camera->getRenderTexture();
    renderTexture->refresh();
   

3. Save the Render Texture to a File

    OcularResources->saveResource(renderTexture, File("screenshot.png"));
   

All together:

auto camera = OcularCameras->getMainCamera();

if(camera)
{
    auto renderTexture = camera->getRenderTexture();

    if(renderTexture)
    {
        renderTexture->refresh();
        OcularResources->saveResource(renderTexture, File("screenshot.png"));
    }
}
