everybody what is going on welcome to another pine tutorial video with pie

opengl in Python so where we left off we were basically pulling in these mouse

buttons we found out that for us forward five is reverse and now i'll show you

guys how can utilize this zoom in and out of our object so we want to do if

event . button is a four then we want to GL translate f 0.0 0.0 and 1.0 then

we'll go ahead and just run l if event . button equals five GL translate f 0.000

and 1.0 actually this is negative one pointer and that was soon for us we're

going to turn off rotate for now you'll see why in a moment let's go ahead and

save it run it there is our cube now we come on screen and we'll scroll your

mouse and you'll see how we are zooming in and out now now it's going to turn

rotate so rotate there's our cube awesome and see how his role it's almost

like it's it's like we're having a really hard time controlling it and the

reason for this is you need to understand what uh what is happening so

when we zoom it's like it's affecting like us right but we're also zooming in

and out of the actual cube which is spinning and then each time we zoom

basically resuming in and out from a different kind of perspective and so

that's what makes this really confusing initially hear it

we've lost it but here's an example let's do let's turn to go

rotate will do 0 0 and 0 see how that looks for us right

and so now we're just zooming in and out of this cube okay easy enough

and then what I want to go ahead and do let's make this and we need to make at

let's do X as five

ok so now you can see it's going like forward and reverse now what if let's

change this to its not so steep

ok oops one more time

okay now this is a good idea or a good time to show you clips or clipping so we

could change this 25 and this to 10

ok so as we zoom out we can see it but as resume for we see that the cube is

being clipped away right

based on our view so as we get closer to it it's like chop it's slicing off the

top of the queue basically we can also get a better look at that

let's do 20 let's try that right so as the cube comes closer to us it's being

clicked away and then as it moves away from us it's also being clipped away the

more you know

ok so that's that uh and let's see if traffic there's anything else I really

want to show you as far as inside perspective for example for me this 90

and we zoom al

ok so you can see that let us see if there's anything else i really want

joe know that covers as far as like what zoom what I would want to show you guys

so anyway that's that we could turn back on on rotate and rotate really shows it

well there's still a couple of things I definitely want to show you guys

especially like coloring and stuff like that so sitting to next video for that

as always thanks for watching
