Blender 3D 2.49: Working with Textures

by Allan Brito | September 2010 |

In this article by Allan Brito, author of Blender 3D 2.9: Architecture, Buildings, and Scenery, we will take the realism of our scenes to a higher level using textures. With textures, the "magic" really happens! There are basically two types of textures, which are procedural and non-procedural textures. For us, the bitmap textures will be used most often, to allow us to create scenes with more realism.

In addition, we will learn how to:

  • Choose and organize textures
  • Apply and setup a bitmap texture
  • Map a texture around a model
  • Use normal maps
  • Create UV Layouts to create more complex textures

Examples of MySQL Daemon Plugin

by Andrew Hutchings | August 2010 | MySQL Open Source Web Development

In the previous article, A look inside a MySQL Daemon plugin, we were introduced to the MySQL Plugin API. It talked about the most simple plugin type—Daemon plugins. It starts with the basic structure of a plugin—what a plugin declaration should look like, what plugin types are, and so on. Then it described features common to all plugin types—initialization and de-initialization callbacks, status variables, and configuration system variables.

This article, by Andrew Hutchings, co-author of MySQL 5.1 Plugin Development, describes and analyzes line by line four Daemon plugin examples—from a simple plugin that prints Hello World! when loaded, to a system monitoring plugin that periodically logs the number of connections, to a system usage status plugin that displays the memory and I/O usage of the MySQL server.

We will specifically cover:

  • A Hello World! Daemon plugin
  • A system and status variables demo plugin
  • A simple monitoring plugin
  • System Status Variables plugin

MySQL 5.1 Plugin: HTML Storage Engine—Reads and Writes

by Sergei Golubchik | August 2010 | MySQL Open Source Web Development

In this article by Sergei Golubchik, co-author of MySQL 5.1 Plugin Development, we will consider a complex example, a complete read-write storage engine, but with no support for indexes. Let's say, it will be an "html" engine—an engine that stores tables in HTML files. Such a file can be later loaded in a web browser and the table will be shown as an HTML table. Thus Reads and Writes presents a storage engine plugin that keeps table data in HTML tables and uses it to explain how to implement an updatable data stores.

Python Multimedia: Fun with Animations using Pyglet

by Ninad Sathaye | August 2010 | Open Source

Animation is a sequence of frames displayed quickly one after the other. This creates an optical illusion where the objects, for instance, appear to be moving around. This article by Ninad Sathaye, author of Python Multimedia Beginner's Guide, will introduce you to the fundamentals of developing animations using Python and Pyglet multimedia application development frameworks. Pyglet is designed to do 3D operations, but we will use it for developing very simple 2D animations in this article. Specifically, we will:

  • Learn the basics of Pyglet framework. This will be used to develop code to create or play animations.
  • Learn how to play an existing animation file and create animations using a sequence of images.
