In this chapter we'll look at applying the modeling tool kit to real world scenarios. One of the most common things that you'll want to do in modeling is to retopologize an existing model. And that of course means to preserve the model's overall shape But, change the structure or the topology. For example, this ducky that I modeled, is very simple. I modeled it just by extruding cubes and then smoothing. And what that's resulted in, is basically a not very good structure to the ducky's face.
So if I wanted to animate this ducky, he wouldn't really be able to emote very well, because I wouldn't be able to deform his face terribly efficiently. And the reason of course is that, these edge loops are not conforming to the contours of the ducky's face. So what I'm going to do here is, I'm going to build a brand new surface off of the existing one here that will have good topology. So to make that happen, I want to go to the Modeling Toolkit and under Transform Constraints, I'll choose Other Surface. Then I'll choose the object that I want to build off of.
So I've selected ducky body there. Now, I can scroll down a little bit and you'll see in the Mesh Editing tools, we've got Quad Draw. And as soon as I click Quad Draw, now the modeling toolkit has become active. So you can see up here, it's become active and we're dropped into multi component mode. And what I want to do here is start drawing. And I'll just click to create vertices. And I want to basically build quadrilaterals that conform to the existing shape. So once I've got four vertices there, then I can hold down the shift key and position the cursor and what you will see is a preview of the polygon that we're about to create.
And then click and the polygon is actually built. Once that polygon exists, now we've actually got a new object in the scene. If we look in the outliner, you'll see we've got something called polysurface1. So that's the new object. So in fact, when we clicked to create that polygon, we created an entirely new shape and a new transform note. It's a new mesh object. Okay. So I'm going to continue drawing vertices. And I'll just go ahead and click a couple times here to make two more vertices. Hold down shift and click to create another polygon.
And I can just keep on going down the line as much as I need to, to create that entire polygon loop. Now when I get to this last one here, I don't need to create any more points because they are already there. Just hold down the shift key, and click. And it's created a closed loop. Very cool, alright. So, now, I can adjust this as well. I can move these points around just by holding down the middle mouse button. And that enters Tweak Mode. So that's the first step in Retopologizing a model. We can also delete components from the Quad Draw tool.
All you have to do is hold down the Control key. And then hover over a component such as a face and then click to delete. And also delete vertices, Ctrl+click on those to delete the entire face. And go back to building, clicking these vertices, hold down shift and shift to create those polygons.
