Methods and systems for creating applications using scene trees
Systems and method for creating applications are disclosed. In embodiments, the system includes a visual editing environment configured to receive code that defines an application using a declarative language from one or more developers, wherein the code includes a scene tree description; a code execution engine configured to operate on the code created in the visual editing environment to create a scene tree that defines properties and behaviours of the application based on the scene tree description; and a publisher configured to publish the application, whereby instances of the application may be downloaded to respective client devices, wherein each instance of the application includes a respective instantiation of the scene tree, wherein the scene tree description is editable via the visual editing environment, such that edits to the scene tree description are updated to the respective instantiations of the scene tree at runtime.
1. A system for creating applications, comprising:
one or more processors; and
at least one memory, wherein the one or more processors and the at least one memory implement:
a visual editing environment configured to receive code that defines an application using a declarative language from one or more developers, wherein the code includes a scene tree description;
a code execution engine configured to operate on the code created in the visual editing environment to create a scene tree that defines properties and behaviours of the application based on the scene tree description, wherein the scene tree is a set of objects that collectively define the properties and actions of the application; and
a publisher configured to publish the application, whereby instances of the application may be downloaded to respective client devices, wherein each instance of the application includes a respective instantiation of the scene tree,
wherein the scene tree description is editable via the visual editing environment, such that edits to the scene tree description are updated to the respective instantiations of the scene tree at runtime,
wherein the visual editing environment and the code execution engine enable creation, delivery, and editing of the digital asset during runtime, such that a plurality of end users using different devices can simultaneously experience a same behavior of the digital content asset during its creation and editing, and
wherein the code execution engine governs execution of the code across a plurality of computer operating systems.
2. The system of claim 1 , wherein the set of object of the scene tree is a hierarchical map of objects.
3. The system of claim 1 , wherein the scene tree specifies respective page layouts of the application.
4. The system of claim 1 , wherein the set of objects of the scene tree include one or more variations that manage different states of the application.
5. The system of claim 4 , wherein the one or more variations define different languages that are presented in the application.
6. The system of claim 4 , wherein the one or more variations define different operating systems that can host the application.
7. The system of claim 4 , wherein the one or more variations define different layouts of the application.
8. The system of claim 4 , wherein the one or more variations define whether to override objects, properties, or actions of the application.
9. The system of claim 4 , wherein the one or more variations define one or more custom states that are specific to the application.
10. The system of claim 4 , wherein the one or more variations are defined using variation rules that define different properties of the application based on the different states of the application, wherein each variation rule is either true or false in a given scenario.
11. The system of claim 1 , wherein the scene tree description is simultaneously editable by multiple users.
12. The system of claim 1 , wherein the code execution engine controls utilization of at least one of a CPU and a GPU of a client device upon which the digital content asset runs.
13. The system of claim 12 , wherein control of utilization includes specification and execution of instructions for optimization of thermal performance of the at least one of the CPU and the GPU.
14. The system of claim 1 , wherein the code execution engine governs execution of the code across a plurality of operating systems to provide a consistent user experience with the digital content asset.
15. The system of claim 14 , wherein the code execution engine governs execution of the code across a plurality of mobile operating systems.
16. The system of claim 15 , wherein the mobile operating systems are selected from among IOS®, Android® and Windows® operating systems.
17. The system of claim 1 , wherein the code execution engine enables control of network layer interactions for the digital content asset.
18. The system of claim 1 , wherein the code execution engine enables control of browser interactions for the digital content asset.
19. The system of claim 18 , wherein the browser interactions include Comet interactions, HTTP streaming interactions, Ajax push interactions, reverse Ajax interactions, secure socket interactions, and HTTP server push interactions.
20. The system of claim 1 , further comprising a plug-in system for orchestrating components and events for the digital content asset.
21. The system of claim 20 , wherein the plug-in system is a Javascript plug-in system.
22. The system of claim 1 , wherein the code execution engine is a low-level binary that targets different cross platform device architectures.
