Hello,
What’s the C++ equivalent of base.camLens to get the default lens? The problem is I’m creating my own lens which can’t be right.
LPoint2 mousePoint = Application::GetWindow()->get_mouse();
LPoint3 from(0,0,0);
LPoint3 to(0,0,0);
PerspectiveLens lens;
bool result = lens.extrude(mousePoint,from,to);
from = Application::GetWindow()->get_render().get_relative_point(camera_,from);
to = Application::GetWindow()->get_render().get_relative_point(camera_,to);
printf("MouseHandler::SetTarget from:x %d y: %d z: %d\n",
from.get_x(),from.get_y(),from.get_z());
printf("MouseHandler::SetTarget to :x %d y: %d z: %d\n",
to.get_x(),to.get_y(),to.get_z());

PT(Lens) myLens = window_framework->get_camera(0)->get_lens();
myLens->extrude(...);

I’m getting some insane values for the to Point. What does that indicate, the ray is not hitting anything? It should be hitting my Bullet objects according to the cursor.
LPoint2 mousePoint = Application::GetWindow()->get_mouse();
LPoint3 from(0,0,0);
LPoint3 to(0,0,0);
PT(Lens) lens = Application::GetWindow()->get_camera(0)->get_lens();
bool result = lens->extrude(mousePoint,from,to);
from = Application::GetWindow()->get_render().get_relative_point(camera_,from);
to = Application::GetWindow()->get_render().get_relative_point(camera_,to);
printf("MouseHandler::SetTarget from:x %f y: %f z: %f\n",from.get_x(),from.get_y(),from.get_z());
printf("MouseHandler::SetTarget to:x %f y: %f z: %f\n",to.get_x(),to.get_y(),to.get_z());But the output is something like:
Why is the to value so large?
Cheers,

No collision detection is being performed by Lens. These are the points on the near plane of the camera and the far plane on the camera corresponding to the given mouse position.

Yeah I realised I’m not doing the Raytest
That’s just the conversion. I think I’ll pack it in for today
