AuntiAlias: I didn't realize the ambiguity until now! hmmm I seem to be stuck here... not seeing stuff show up AuntiAlias: oops! all filled in! okay! : ) gdmsynth: Well the space bar pan is very convient for setting up a scene. AuntiAlias: you can move the camera in an animation..... that is a 3D camera move... i.e., a move in space gdmsynth: Option and Control Trackball are also equally useful. AuntiAlias: and you can pan the 2D "film" inside the camera... to see this thing here.. and then that thing there.... PJF88: I'm not sure if you mentioned this when I disappeared back there, but using the scroll (spacebar/hand) thing instead of the main camera trackball to move the horizon can cure the problem of converging verticals. gdmsynth: A setup tool? AuntiAlias: one reason for ambiguity is that the camera controls were all named for still image camera things before an animating camera came into being... kidna like a Bryce Scene being a place... and an animation is what? a scene? no, I think "sequence" is better... gdmsynth: I think they translate well to animation too though. AuntiAlias: If you think about the 2D film plane being much bigger than what's possibly visible at one time, you can "pan" around that 2D film plane.... That's what the Pan control is.... gdmsynth: When you animate, you can use the track ball in the camera mode with the Control and Option keys I think. AuntiAlias: and what we think of with motion pictures.. a camera pan... is some sort of a camera move gdm, tell us a bit more about control and option keys and trackball gdmsynth: What happens if both Pan and camera drag are animated I wonder? In the camera mode I think you can just hold the Option key and rotate the track ball for altitude. AuntiAlias: gdm, when you finish that animation that answers your question, please do post the url so we all can see the results! :D (option = alt) gdmsynth: And the Control Key and Trackball for Horizontal adjustment. JeffP: ? AuntiAlias: right... you move only on one dimension.... gdmsynth: ;-) AuntiAlias: Okay, we'll take Rosy's question and then Jeff's Rosy-- go for it! gdmsynth: Thanks. Rosy: What FOV setting is best to minimize distortion in the view of parallel objects (like sides of buildings, etc.)? thanks! AuntiAlias: whatever one works! :D AuntiAlias: actually for that one... here's what I do PJF88: I just mentioned that above Rosy. Rosy: I saw that too AuntiAlias: I set the field of view to lower number... then I have to move the camera back so it takes in more AuntiAlias: it's similar to being far away and lookgin at someting with telephoto lens Rosy: great idea! thanks /ga AuntiAlias: PJF also mentioned scrolling around as a way of altering what's in your window w/o distorting the "perspective" tho if you scroll way way off center, there will be distortion.... since Bryce's camera is similar to a pinhole camera Rosy: yeah PJF that is another method I must try@ AuntiAlias: the farther off of center, the more apt there is to be distortion you see that more clearly when you zoom out.... gdmsynth: Excuse me, but where does Scale fit in there? AuntiAlias: center of image looks okay, but around the perimeter is more distorted uh zoom out = scale so.. it fits in exactly right here! :D PJF88: It's kinda like large format cameras with adjustable film and lens planes. (panning) AuntiAlias: Jeff.. your question?. JeffP: To do a movie type "tracking shot" would I use Pan? AuntiAlias: no... that gets to the tip I wanted to talk about.... which is how to aim the camera if you are tracking something or rather I meant to say If you are tracking... you are tracking some thing.. an object Bryce gives you the ability to do that... two ways to do so.. . one in wireframe view, other in camera atts dgb oops dialog box wireframe view: you have to be in director's view, or one of orthogonal views so you can see both the camera object and the object that it's gotta track (I'm doing this in Bryce as I describe it... so feel free to follow along) I'm in top view, so I see camera. I also have a sphere in my scene When I select camera, there are the object icons AuntiAlias: the A and the family color, and a diagonal linking one, and the one under neath that is a target... square corners and interior square... think of it as cross-hairs, for targeting you position mouse over that icon, and then drag from that icon to the obect you want to track AuntiAlias: as long as your mouse is down, there's a blue line extending from camera to your mouse position wahtever object your mouse passes over turns blue you drag to your target object... when it turns blue let go camera immediately jumps to center in on object a gray line extends from camera to object so caemra is TRACKING that object in Camera view, that object will be smack dead center of screen ....unless of course.... you set up your pan V or pan H to be something different and then object will be offset from center accordingly..... so in animation... don't animate the camera animate the object camera will definitely TRACK it! : ) and here's a NIFTY NIFTY trick! MtnCub: cooool Rosy: ah gdmsynth: If you don't do it the way Aunti says, and you animate the camera rotation, no matter how smoothly you tweek the AMS curves you'll still get a little jump at the end.
