now that we know how to plot points on a coordinate plane we're ready to start designing a shot let's take a closer look at this sketch that we got of Andy's room from Toy Story we can see that buzz and bo-peep are lay down on the floor and on the bed and sort of a haphazard sort of way we can also see in this sketch that there's a question where do we want to put the lamp do we want it next to the beds so that the person who lives here can use it or do we want it on the dresser to mean that the adult is using it everywhere you put something means something and really good computer graphics tells a story in every single placement of every single prop to build the shot we've received this set of objects from the modeling department to work with at Pixar we call such a collection a model catalog since in this lesson we're working in 2d R objects or 2d images but when we do this for real and a Pixar movie our assets or three-dimensional models in either the 2d or 3d case we pick a reference point on the object to aid with placement we could choose any reference point we like in this lesson we'll choose the lower left corner objects right into the shot from the model catalog will appear with the reference point at the origin to layout my shot I'll start with the dresser since it's one of the bigger forms I'll need to work with once the object is in the shot I can position it wherever I want using the translation operation for instance let's move it five units to the right and five units upwards to translate the entire object we have to translate each point in the object so if I pick this point on the initial object call its coordinates x0 and y0 it gets moved to this point after translation call the coordinates of this translated point x1 and y1 this formula over here tells us that the mathematics of translation is addition as I click on a point in its initial position you see where that point goes as well as what's happening to the coordinates so whenever you see objects changing position in our films you know that translation and therefore addition is going on under the hood your first assignment is to select objects from the model catalog to create a first pass at that drawing you got from the story department to keep things simple for this first assignment we've only given you the translation operation so you won't be able to lay out the whole shot your job is to figure out which objects you can place using only translation you shouldn't pick objects that are going to require resizing or rotation just yet and if you add an object by mistake you can always click remove good luck
