There are 12 principles in the production of an animation that are taken into account to ensure that the best possible product can be created. One of the principles used in animation is “Pose to pose and Straight ahead” this relates to the way in which an animator constructs their animation. For example in the 2D medium and animator will create keyposes or storytelling poses which are the most important or significant extremes and positions of the motion. The animator then draws the frames inbetween keyposes to complete the animation and give it a clean motion, this is the pose to pose method of animating.
Opposing this method is straight ahead, this method instead involves an animating as you go kind of approach to creating an animation. This means that instead of creating keyframes and connecting the dots with inbetweens all the frames are created as they appear in the animation. This often proves to be a more difficult approach to animating but is capable of creating some appealing results.
When this Principle is applied to the 3D medium it can be used in a similar way to create a similar result. Like in the 2D medium keyposes can be created in the 3D medium, the computer then creates the inbetweens and we adjust them to suit. This is effectively the pose to pose method applied to the 3D medium. The straight ahead method would involve creating each keyframe as you go in the same way as the 2D medium. However as the computer interpolates the data in order to get a true straight ahead you would need to adjust the curves in the graph editor as you work. This method would be fairly complicated to achieve but would likely produce a similar result to straight ahead animation in the 2D medium.
