Applying Concepts
Knowing theory is good but it's just the first part of the journey. This video is meant to teach application and a truly fathom the fundamentals. Put all your knowledge together and create a real scene. We chose to model a tank, inspired from the T-55 russian model, because it had a rich set of modeling features. Learn new modeling techniques, both procedural and non procedural. - Keywords: houdini training, sidefx

Rigging Caterpillars
The tank follows a path on a bumpy terrain . One of the main challenges of the modeling is to create a pair of caterpillars and a set of wheels that properly adapt to the terrain as the tank goes on.The tank is modeled in relation to a future animation. The same as with characters we refer to this process as rigging a vehicle. Here, Houdini's non-procedural paradigm fuses with animation, since the animation now become the input of your modeling process ( like in the famous CHOP-based scene of the film The Grinch).

Modeling Variety
This project has all the types of modeling, polygonal, nurbs, subdivided polygons, and painting details. We show you a great diversity of SOPs. Extrude, bevel, creep, refine, trim, carve, intersect, fillet, join polywire and the list goes on. Some tactics are more explicitly procedural. Some other are more artistic. Like real-world scenarios which are always a blend of both.

Polygonal Modeling Tools
Groups, procedural selection, beveling, creeping, and joining... Houdini has an extremely powerful set of polygonal tools, and we will show you how to make the best of them in a fair amount of time.

NURBs Modeling
Before we dive into nurbs modeling, we make a quick yet thorough reminder about NURBS, their properties. Isoparms, profiles, parameterization, topology, stitching, detailed u/v skinning scenarios are covered. These are some concepts you must be familiar with to be proficient with NURBS. Learn Houdini's very specific way to work with NURBS and how you can define more complex NURBS surfaces than in the other softwares.

Creating Details
In this section, we introduce you to a very Houdini way of working. Add some details on your tank, like grips for the driver of the tank or rivets. Instead of tediously placing them, or using a displacement map, paint them. Learn how you can combine painting with any operator of Houdini to interactively and artistically create some details like grips on the tank.

Putting It All Together
This video is intended to be the first step in creating a scene. You want to apply a camouflage shadier for you tank, you want to add grass, global illumination. You want to instantiate your tanks, and drop a bomb on them. Instead of creating a scene out of pre-built elements coming from nowhere, we build each step with Houdini.
