image between every two frames, and composites each frame and the following sub-frame into a single image with two fields. The result is a 60 fields-per-second animation suitable for play on an NTSC on page 8059 television monitor. Field Order When you render to fields, you also specify a field order to identify which field comes first. The Field Order configuration setting is found in Preferences, on the Rendering page. A frame's scan lines are numbered and each field contains either the odd or even scan lines. The video source (for example, broadcast transmitter, video tape recorder, or digital video recorder) determines which group of scan lines is in each field and which group is delivered to the display first. The fields are referred to as Field 1 (F1) and Field 2 (F2); either could contain the odd numbered (1st, 3rd, 5th, and so on) scan lines or the even numbered (2nd, 4th, 6th, and so on) scan lines in the frame. Using the default setting of Odd as your Field Order preference, the software renders the first field image (F1) to the odd scan lines. If the field order preference is set to Even, then the first field image is rendered to the even scan lines. For an image to display properly, the field order and the video device field order must match. Some video systems require odd lines to be rendered first, and others require the even lines to be recorded first. The Field Order parameter is set to Odd by default. If you observe incorrect strobing in your video output, change the parameter to Even. Figure Mode When you work with a biped on page 4147, you use Figure mode on page 4420 to fit the biped to the mesh or mesh objects on page 8043 that represent your character. You should have Figure mode turned on when you attach the mesh to the biped with Physique on page 4603. Figure mode is also used to scale a biped that has a mesh attached to it, to make biped "fit" adjustments after Physique is applied, and to correct posture for motion files that need a global posture change. When Figure mode is turned on, the biped jumps from its animated position to its Figure mode pose. Animation is preserved when you exit Figure mode. The parameters on the Structure rollout on page 4424 are active only in Figure mode, and at creation time. 7974 | Glossary
