Alias vs. subdivisions vs. Maya

“

- [Instructor] Before we get started, you may be wondering why would be used subdivisions over Alias or Maya. And also what is the difference in the actual appearance between these three applications? So on the screen right now, I have three models. I have an Alias model, I have a subdivision model and I have a Maya model. And these models are all created in different courses that represent the F1 steering wheel. So let's go up to Object Display, and we'll go to Diagnostic Shading, and we can shade with any one of these. And you'll notice that they all shade very, very similar. So I want to switch off the actual Wireframe right now by going to Windows, Toggle, Toggle model. And going back to the question, why would you use one of the other? Again, it's down to experience, it's down to how much time you have for your deliverable. You may only have a couple of hours in which case it makes more sense to maybe jump into Maya or SubD rather than going through the whole block, fill it method of creating a model in the Alias application. So as I rotate this round, you can see between the three models, there is a very, very little difference if any at all. So just to prove the point that you can actually use a subdivision model in a visual representation, and it will give you exactly the same results as if the model was created in Alias or Maya. The other advantages, if I go back up to Toggle and let's bring the model back and I'm going to switch off the shading, just go back to Wireframe. Let's go ahead and just pick all of those entities and we'll switch on the CVS. You'll notice now with Alias and SubDs and that we have the underlying geometry is Nurbs and Bezier based. So you can actually salvage a lot of this information downstream as you go in more into the class A mode. With Maya, you'll notice that these are all polygons and with polygons, you can only treat this as purely scan date. You really can't salvage this into a Bezier and Nurbs world, or at least it's not very easy to do so. So typically what I would do, is I would just use this data as reference or a scan data and start building on top. Whereas with the SubDs and with Alias as you can see here, we can actually start dissecting this and salvaging a lot of this information and applying it into the Nurbs and Bezier world.
