Blender 2.49 Scripting: Shape Keys, IPOs, and Poses

by Michel J. Anders | April 2010 | Open Source

The Blender API provides us with the means to define IPOs from scratch, enabling the definition of movements not easily re-created by setting key frames by hand. Thus there is more to IPOs than just driving one IPO by another one. Furthermore, Shape keys and poses are examples of (collections of) IPOs that are quite different from, for example, a location IPO. We will encounter both shape keys and poses later on in this article, but we will start off with looking at how we might define an IPO from scratch.

In this article by Michel Anders, author of Blender 2.49 Scripting, you will learn how to:

  • Define IPOs
  • Define shape keys on a mesh
  • Define IPOs for those shape keys
  • Pose armatures
  • Group changes in poses into actions

(Other related articles on Blender 2.49 Scripting are listed at the end of this page.)

Working with Value Extractors and Simplifying Queries in Oracle Coherence 3.5

by Aleksandar Seovic Mark Falco Patrick Peralta | April 2010 | Oracle

Usually you can access data in the Coherence cache using identity-based operations, such as get and put. In many cases this will be exactly what you need, but there will also be many other situations where you either won't know an object's identity or you will simply need to look up one or more objects based on attributes other than the identity.

In this article by Aleksandar Seovic, Mark Falco and Patrick Peralta, authors of Oracle Coherence 3.5, we will cover:

  • Built-in filters for querying the Data Grid
  • Implementing a custom value extractor
  • Implementing a FilterBuilder class that will allow us to define the queries in a simpler way

Database Interaction with Codeigniter 1.7

by Adam Griffiths | April 2010 | Open Source PHP Web Development

Having seen form validation in the previous article, we will now cover database interaction. Databases are the backbone behind any Web application. Without a database, you'd have nowhere to hold all of your data, and SQL queries can become long and cumbersome to type out. Thankfully, CodeIgniter gives us a brilliantly simple way to interact with our Database. The database library also makes changing between database types—from MySQL to Oracle, for example—easier, because it acts as a wrapper and provides many functions for us to use on the database.

In this article by Adam Griffiths, author of CodeIgniter 1.7 Professional Development, you will:

  • Perform database queries with the database library
  • Return query results using the database helper functions
  • Create queries using the active record library
  • Learn how to cache active record queries
  • Modify database tables using database forge

Form Validation with Codeigniter 1.7

by Adam Griffiths | April 2010 | Open Source PHP Web Development

Form validation is an important part of any application. Take a look at your favorite web application, notice that there are many forms in these web apps, and it is important that they be secure. It is also important that you have rules that should be adhered to; this also helps to keep a layer of security.

In this article by Adam Griffiths, author of CodeIgniter 1.7 Professional Development, you will:

  • Learn how the form validation process works
  • Build a contact form
  • Apply validation rules to the form's input fields
  • Use callbacks to create your own rules

We will cover database interaction seperately.
