示例1: SetBoundingBox
void EC_SelectionBox::SetBoundingBox(QRect &view)
{
if (world_.expired())
return;
OgreWorldPtr world = world_.lock();
Renderer* renderer = world->GetRenderer();
Ogre::RenderWindow *renderWindow = renderer->GetCurrentRenderWindow();
float w= (float)renderWindow->getWidth();
float h= (float)renderWindow->getHeight();
float left = (float)(view.left()) / w, right = (float)(view.right()) / w;
float top = (float)(view.top()) / h, bottom = (float)(view.bottom()) / h;
if(left > right) { float tmp; tmp = left; left = right; right = tmp; }
if(top > bottom) { float tmp; tmp = top; top = bottom; bottom = tmp; }
// don't do selection box if too small
if((right - left) * (bottom-top) < 0.0001) return;
// correct coordinates for overlay
left = left * 2 - 1;
right = right * 2 - 1;
top = 1 - top * 2;
bottom = 1 - bottom * 2;
selectionBox_->clear();
selectionBox_->begin("BlueTransparent",Ogre::RenderOperation::OT_TRIANGLE_STRIP);
