4 new blender features were added to trunk. Most of Blender users have probably heard rumors of these features for a while, but now they are finally available to play with. These features are significant andopen the new ways in using Blender in the future.
Cycles- New improved rendering engine, more realistic renders
Cycles is a completely new way of rendering in Blender that produces far superior results to the outdated internal renderer. Bounce lighting, caustics and glass are now available as standard without any messing around. Cycles will eventually replace the internal rendering engine, becoming the standard that every Blender user will soon use.
Camera Tracking - Allows you to add 3d elements to moving video footage
You can now track camera motion, add 3d elements, composite it, render it and edit the video, all without leaving Blender.
Dynamic Paint- Makes the environment react to interaction
When a character walks through snow, or a car skids it’s tires, it helps to have the environment react accordingly. The way it works is by baking animated textures onto the objects surface. These textures can these be used for reflections, displacements or anything else you wish.
Ocean Simulator- Allows you to simulate a realistic ocean
A much desired feature for the nature buffs out there is the ability to create realistic oceans. Whilst this may seem like a rather specialized feature, oceans are an incredibly necessary part of 3d work as they make up 2/3 of the earth, and without a dedicated feature they are almost impossible to create realistically.
