HijackGL: Reconstructing from Streams for Stylized Rendering
Alex Mohr and Michael Gleicher
Abstract:
This work shows that intercepting a low-level graphics library command
stream and reconstructing a declarative representation is practical
and useful, especially for exploring new rendering styles. We show not
only how the basic mechanics of intercepting an OpenGL command stream
lead to a non-invasive extension mechanism for graphics applications,
but also how simply manipulating the stream severely limits the kinds of
effects we can consider. We describe how our system efficiently
reconstructs a declarative representation of the geometry implicit in
the graphics library command stream. We present a set of application
extensions built with this framework, including several stylized
renderers. Extensions built using our system are capable of changing
the rendering style of applications on the fly at interactive rates.
