3D Animated Widgets

pkpovray generates 3d widgets pixmaps using povray. It defines a process of writing scenes in python and storing the images as a qt resource, ready for use as a pre-packaged widget. (milestone:pkpovray-0.2)

button = SuperEllipsoid(.3, .15,
                        pigment=Pigment(color=WHITE),
                        finish=Finish(phong=.3),
                        scale=(X_SCALE, .3, .45),
                        translate=(0, -.1, 0),
                        )

Components

• pk/povray/sdl.py: Write povray scenes in python.
• bin/pkpovray: Manage widget packages.

Basic Concepts

• Widgets are animated using pixmaps generated from povray.
• Povray scenes are written in python using pk/povray/sdl.py
• Widget attributes (size, etc) are set in a simple xml project file.
• Each frame is rendered using the easily batched bin/pkpovray.
• Widget pixmaps are cropped to the widget size using a simple xml project file.
• Qt4's resource system is used to load the pixmap data, and superclasses are provided in pk/widgets/pixmapwidgets.py

Quickstart

• Write scenes in povray.
• Add clock functions to animate your scene.
• Render the widget's pixmaps using the scene.
• Crop the pixmaps with pkpovray.
• Use pkrcc to generate a qt resource file.
• Use pyrcc4 to embed the pixmaps into a python module.
• Subclass a widget class from pk.widgets.pixmapwidgets.

Examples

• resources/povray/widgets: My widgets
• resources/povray/widgets/render: batch render script.
• bin/pkdemo: The script for the screenshot above.
