1 Brief introduction to Blender
Explain Blender as a fully featured 3d suite: modeling, animation, compositing, etc.
1.1 Show a couple of render stills
1.2 Possibly show a couple seconds of a python-generated animation
2 Brief demo of UI
2.1 Open a new file
2.2 Add a cube
2.3 Show the cube being animated from point A to point B
This should be pretty quick to demonstrate. Will be necessary for explaining the Blender's datastructure next.
3 Introduction to bpy
3.1 What is it?
- bpy is Blender's new Python API
- Pretty much a complete overhaul of the Python API in 2.5X from the 2.4X and previous API
- A lot of it is "automatic" thanks to the RNA and operator designs of Blender 2.5X
3.2 bpy.data: Exploring Blender's datastructure
3.3 bpy.ops: Operators
3.3.1 Discovering operators for your scripts: Blender 2.5 is self-documenting
- Grab and move a cube, look at the logging
- All key commands are bound to operators, all buttons are operators.
- We can find a python equivalent by doing an action and checking the logging or
3.3.2 bpy.types.Operator.execute(): operators as actions
Demonstrate some hello-world type examples
3.3.3 bpy.types.Operator.draw(): operators as UI elements
- Demonstrate some hello-world type examples
- Also demonstrate properties-as-ui-elements
3.4 Panels in the UI
Scripting the UI is pretty much the same as scripting the operator, but it goes to a separate location..
4 Some real-world examples
4.1 The simple "library loader" panel we're using in Tube
4.2 Making tools for the wargames-esque animation from Patent Absurdity
4.3 The Gilga rig panels from Tube
