//Menu: label Summary
|
|
|
|
.Three Layers
|
|
Besides the (obvious) separation in GUI frontend and render engine, editing core and application logic
|
|
are treated separately. Besides enforcing clearly defined interfaces, the ability for script driven
|
|
``headless'' operation and extensibility by plug-ins are deeply rooted in the overall design.
|
|
|
|
.Strong Separation
|
|
High-level and low-level realm remain cleanly separated, relying on a compiler-like translation mechanism.
|
|
This way, each part can be optimised for its purpose. The GUI exposes a feature-rich session model close
|
|
to the problem domain, while the engine operates on a performance optimised render nodes graph.
|
|
|
|
.Scheduling Micro Operations
|
|
High performance calculations in the engine are organised as micro tasks to be scheduled,
|
|
allowing for adaptation to current and future hardware, expected to operate increasingly parallelised.
|
|
|
|
.Intelligent IO
|
|
The engine is backed by an sophisticated frame cache and self adjusting I/O manager for maximising throughput
|
|
and bandwidth use.
|
|
|
|
.Stream Type System
|
|
Instead of relying on a single media framework, data streams are abstracted and classified, allowing to
|
|
handle most wiring, detection of possible connections and conversion automatically.
|
|
|
|
.Rules Based Configuration
|
|
Rather than driven by hard wired default behaviour or tedious manual operation, control flow is guided by
|
|
a set of rules shaped configuration, which scales better to large and complicated projects. Queries are
|
|
issued at decision points, allowing to build up a work environment customised and tailored for the needs
|
|
of specific projects.
