Hey all, this is my first post :banana: but unfortunately it is not to throw much deserved praise at all the amazing work I see in these forums :( . Reading all the work in progress and viewing images submitted had re-awakened my desire to join the 3d computer animation/ imaging world, hence forth I tried the free trueSpace 3.2 (Think that’s the version), went on to buy the trueSpace 4 and am now the proud owner of trueSpace 6.6! And I’ve got to say I love it already!
Anyway, enough about that, my problem is as follows, its to do with the screen distorting.
Being a newbie to trueSpace 6.6 I find the courses brilliant for teaching and getting to know all about the features it has to offer. I am currently having a lot of fun with the MusicMaker course but have run into some trouble…
When I zoom out to see the whole object, the screen kind of distorts, even the navigation widget in the bottom right corner gets stretched and I can’t zoom out no more. I want to get the view that is shown in the course where the abject is correctly proportioned. There is no problem with this in the video course. Any ideas on how to do this?
I have some ideas what’s the problem, but would like to get some expert advice. I think it’s either:
The object is too big? (However, I’m sure I followed the tutorial word for word?)
I have messed around with the original view settings too much
Or I’ve made a newbie mistake somewhere
If I knew how to post images I’d show you what I meant, but unsure how to do so at the min, hope you can understand my problem.
Looking forward to any reply. Cheers. Jimbo |

Try moving the camera/viewpoint back instead of keeping the camera where it is and zooming it in and out (which tS calls scaling). At extremes of zoom the view has to distort, just like in the real world. A very, very wide angle lens on a camera gives that rounded 'fishbowl' effect (these lenses are nicknamed 'fisheye' lenses for that reason). If you simply walk further back from the subject so you can see more you don't get that distortion. |

I hope you have a scroll wheel on your mouse. It's very useful for moving the camera back and forth. I don't even use the zoom thingie anymore. |

If you are looking through a camera, then "zooming out" is just the same as changing the lens on a real world camera - you do indeed get distortion, just like fish eye lenses for instance.
The best way to "zoom out" is to move the camera backward, which is like walking backward with a real camera rather than adjusting the lens. This will avoid distortion.
Can't recall if "perspective view" displays the same thing. However even then I do move the viewpoint rather than zoom the viewpoint.
HTH!

Zooming in perspective per mousewheel doesn't actually change the zoom of the lens, it just moves the viewpoint in or out, which is actually 10 times faster than dragging the viewpoint back and forth. I only use cameras for animations or final renderings. |

What they said!
In perspective view or camera view, the zoom acts like the zoom of a camera. When you zoom way out like that you end up looking through an extreme wide angle lens. Using your left mouse button with the "move" icon active (the two-way arrow as apposed to the full axes icon in the view tools) you can move yourself or your "eye" forward and back, side to side within the scene. With the right mouse button depressed you can change the height of your view.
This wide angle lens effect does not apply in any of the orthogonal views (top, side, etc) and "zoom" is the only way to move in to or away from your object.
If you reach the extent of the view zoom function and still can not see all of your object, perhaps your object should be down scaled a bit. |
