Blender 2.49 Scripting: Impression using Different Mesh on Each Frame of Object

by Michel J. Anders | May 2010 | Open Source Web Graphics & Video

Having covered what script links and space handlers are in the previous article, we will take the discussion further on how Python can be used in Blender. Although softbody and cloth simulators that are available in Blender do an excellent job in many situations, sometimes you want to have more control over the way a mesh is deformed or simulate some specific behavior that is not quite covered by Blender's built-in simulators. This article shows how to calculate the deformation of a mesh that is touched, but not penetrated by another mesh. This is not meant to be physically accurate. The aim is to give believable results for solid things touching an easily deformable or gooey surface such as a finger taking a lick of butter or a wheel running through a soft shoulder.

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

  • How to implement a scheme to associate a different mesh with an object on each frame
  • How to augment the functionality of the 3D View

Blender 2.49 Scripting: Animating the Visibility of objects

by Michel J. Anders | May 2010 | Open Source Web Graphics & Video

There are many places where Python can be used in Blender. In this article by Michel Anders, author of Blender 2.49 Scripting, we will now look at scripts that may be used to act on certain events. These scripts come in two flavors—script links and space handlers. You will learn what script links and space handlers are and how they can be used to perform activities on each frame change in an animation. You also see how to associate additional information with an object, how to use script links to make an object appear or disappear by changing its layout or changing its transparency.

Compiling and Running Handbrake in Ubuntu

by Delan Azabani | May 2010 | Linux Servers Open Source Web Graphics & Video

Handbrake is considered the Swiss Army knife of video conversion tools. Running on the three major operating system platforms, Handbrake can open a huge variety of formats, including common ones that others can't handle (like the titles in the MPEG TS structure of a DVD). Handbrake outputs to a small selection of efficient formats, including H.264/MPEG-4 AVC, MPEG-4 ASP and Theora video. It has advanced features including chapter marking, subtitle inclusion and audio selection, plus filters for optimising video. On Linux, Handbrake can make use of the libdvdcss2 library to decrypt CSS-protected DVDs in-place during encoding, saving the need to use DVD Decrypter or another tool, usually through Wine. This article by Delan Azabani will guide you through the process for building Handbrake, installing it and converting video with it.
