Hệ thống Proxy cho phép bạn sử dụng bản đồ kết cấu proxy trong vị trí của bản đồ có độ phân giải cao trên toàn | Part VIII Advanced Animation Techniques Reversing inserting and scaling time The Reverse Time button flips the keys within the selected time block. The Insert Time button lets you insert a section of time anywhere within the current track. To insert time click and drag to specify the amount of time to insert all keys beyond the current insertion point slide to accommodate the inserted time. The Scale Time button scales the selected time block. This feature causes all keys to be pushed closer together or farther apart. The scaling takes place around the current frame. Setting ranges The Position Ranges button on the Ranges toolbar enables you to move ranges without moving keys. In this mode you can move and scale a range bar independently of its keys ignoring any keys that are out of range. For example this button when enabled lets you remove the first several frames of an animation without moving the keys. The Recouple Ranges button can be used to line up the keys with the range again. The left end of the range aligns with the first key and the right end aligns with the last key. Editing Curves When an object is moving through the scene estimating the exact point where its position changes direction can sometimes be difficult. Function curves provide this information by presenting a controller s value as a function of time. The slope of the function curve shows the value s rate of change. Steep curves show quick movements. Shallow lines are slow-moving values. Each key is a vertex in the curve. Function curves are visible only in the Curve Editor and the Track Bar layout. Function curves mode lets you edit and work with these curves for complete control over the animation parameters. Figure shows the Position curves for a sphere that moves about the scene. FIGURE Function curves display keys as square markers along the curve. 846 Working with Function Curves in the Track View 34 Inserting new keys and moving keys Function curves with only two keys have .
