hi my name is Nicholas and I work in brave making all the trees the forest and all the natural environments of the movie and I use lot of mathematics to do this I think most people think of maths as something boring and mechanical but that's not the way we see mathematics at Pixar for as maths are a tool to create images movement richness and fun this lesson will talk about one of the ways we use mathematics to create the landscapes of brave so let's start with the most simple thing we can find in this landscape one blade of grass one blade of grass is something that's starting a point grows in a direction and bends down it looks like a small seen curve okay this is great news because your mathematics we have lot of tools to describe curves in this case we choose the parabola which is a very specific curve the curve however only gives us the spine the blade we still need to add a thickness to it and a color to make a blade of grass and in order to populate the whole forest we need to create millions of such curves and then give them the right thicknesses and colours in order to create something organic and natural do you want to know more stay with us for the rest of the lesson
