示例1: focusZoomOnMedia
void LLViewerMediaFocus::focusZoomOnMedia(LLUUID media_id)
{
LLViewerMediaImpl* impl = LLViewerMedia::getMediaImplFromTextureID(media_id);
if(impl)
{
// Get the first object from the media impl's object list. This is completely arbitrary, but should suffice.
LLVOVolume *obj = impl->getSomeObject();
if(obj)
{
// This media is attached to at least one object. Figure out which face it's on.
S32 face = obj->getFaceIndexWithMediaImpl(impl, -1);
// We don't have a proper pick normal here, and finding a face's real normal is... complicated.
LLVector3 normal = obj->getApproximateFaceNormal(face);
if(normal.isNull())
{
// If that didn't work, use the inverse of the camera "look at" axis, which should keep the camera pointed in the same direction.
// llinfos << "approximate face normal invalid, using camera direction." << llendl;
normal = LLViewerCamera::getInstance()->getAtAxis();
normal *= (F32)-1.0f;
}
// Attempt to focus/zoom on that face.
setFocusFace(obj, face, impl, normal);
if(mMediaControls.get())
{
mMediaControls.get()->resetZoomLevel();
