5.5. Sampling Issues

Unlike games or simulations, K-3D is a content-creation tool, which has a significant impact on how time behaves. Using the controls provided by the Timeline Panel, users can pause, rewind, skip-ahead, and even “scrub” time back-and-forth in arbitrary ways. An object that takes time as an input cannot assume that time will monotonically increase. Even when rendering an animation, there is no guarantee that frames will be rendered in any particular order, nor that the time delta between frames will be constant - for example, when rendering a scene with motion-blur it is typical to set the current time to the beginning and end of each frame, and possibly to multiple times within each frame, if temporal sub-sampling is enabled. These sub-samples may not be evenly spaced. When rendering the effects of physical shutters on cameras, time-samples may be further offset. :leveloffset: 0
