So on the plane ride back from LA, I whipped up this little sample from what I could remember of the talk. Edit: You can find the talk here: The standard technique for animated water is scrolling normal maps, as I’ve previously written about. The problem with this is that it looks unnatural as water does not uniformly move in one direction.
So Valve came up with the idea of using flow maps ( based on a flow viz paper from the mid 90s ). The Flow Map First we need to create a flow map. Using The Flow Map Now we need to use the flow map to alter the water normal maps. The graph illustrates that during a cycle time from 0 to 1, we want the layer to be fully interpolated at the mid-point in the cycle, and fully un-interpolated at 0 and 1. In the code above, HalfCycle would be .5 if our cycle was from 0 to 1. Top 15 Applications for 3D Artists. With the variable plethora of different applications, scripts, tools, plugins, platforms, engines, and packages available on the market today, how is an aspiring 3D artist (or a seasoned professional for that matter) to know which package he or she ought to be using?
In this article I have attempted to do some of the heavy lifting for you, and narrowed this list down to what is, in my opinion, the top 15 applications out there for 3D artists right now. Enjoy! 3ds MaxOne of most widely used 3D applications by professionals, and students alike, is "Autodesk 3ds Max". Autodesk actually has a ton of programs for 3D modeling, animation, and special effects, but 3ds Max is optimal for someone who is learning 3D, and wants to take it into a profession. The latest release of the software platform is the 2010 version, which has over 350 new features, (including a render-quality viewport display, and the new "Graphite Modeling Tools"). Free great 3d drawing program.

There is a very simple rule that applies in every image and it can make your subjects really appear like they were originally in the shot.
[tweetmeme]In movies the best special effects are the ones you can’t detect. In photomontage applies the same. How many times we look at a montage and instinctively we detect there something wrong; the subject clearly looks superimposed. Rule of Horizon 1. It doesn’t matter if you are sitting, or standing, when you look straight ahead you see the horizon. 2. 3. With this simple rule now you can correctly position and scale different subjects in a composition Here is a practical example. Step 1 Set the Horizon In your background image draw z-axis lines to show the image perspective The point where all the z-lines cross is the vanishing point. This is the horizon Step 2 Place your subjects For this example we will use the same subject so you can better appreciate the effect. Place you subject and scale it. Tags: Design Basics, Quick Tip.
