A device may receive information that specifies a graphical scene. The graphical scene may include a coordinate axis. Data, to be plotted in the graphical scene, may be plotted with regard to the coordinate axis. The device may generate a structured plurality of objects. One or more objects, of the structured plurality of objects, may store properties that define the graphical scene. A particular object, of the one or more objects, may store properties that define one or more elements of the coordinate axis. The device may receive information identifying a modification to an element of the coordinate axis, of the one or more elements of the coordinate axis. The device may modify a property of the properties that define the one or more elements of the coordinate axis, based on the instruction, to implement the modification specified by the instruction.

Rendering graphical scenes

A system may include a memory that stores instructions and a processor to execute the instructions to store a first set of objects in a first data structure, where the first set of objects describe a graphical scene. The processor may create a group of commands and add a command for at least one object, of the first set of objects, to the group of commands. The processor may combine the group of commands into a composite command, where the group of commands includes the added command. The processor may create a second set of objects in a second data structure based on the first set of objects in the first data structure and the composite command. The processor may also modify the second set of objects and provide the modified second set of objects to a browser for rendering the graphical scene.

Object transformation for object trees utilized with multiprocessor systems

A system may include a memory that stores instructions and a processor to execute the instructions to receive data for graphical rendering and distribute a first portion of the data to a first computation process. The processor may distribute a second portion of the data to a second computation process and create a first data structure via the first computation process using the first portion of the data. The processor may create a second data structure via the second computation process using the second portion of the data and assemble an object tree via a third computation process using the first data structure and the second data structure. The processor may provide the assembled object tree to a browser for rendering a graphical scene.

Parallel processing of object subtrees for multiprocessor systems

A system may include a memory that stores instructions and a processor to execute the instructions to create a first set of objects, describing a graphical scene, in a first data structure based on data relating to the graphical scene. The processor may create a second set of objects in a second data structure based on the first set of objects in the first data structure, where at least one object of the first set of objects is associated with at least one object of the second set of objects and one or more properties for an object of the second set of objects is based on information associated with the first data structure. The processor may modify the second set of objects and provide the modified second set of objects to a browser for rendering the graphical scene.

Object trees for multiprocessor systems

A system may include a processor and memory that stores instructions to cause the processor to create a first set of objects in a first structure based on first data, where the first set of objects describes a graphical scene specified by the first data. The processor may add a command for at least one object, of the first set of objects, to a composite command that includes commands for the graphical scene and create a second set of objects in a second structure based on the first set of objects in the first structure and the composite command. The processor may receive second data, change one or more objects of the first set of objects based on the second data, and change one or more objects of the second set of objects based on the changes to the one or more objects of the first set of objects. The processor may further provide the changed second set of objects to a browser for rendering a new graphical scene.

Update traversal of object trees for multiprocessor systems

A system includes a memory, a specialized processing unit and a processor. The processor receives data from a user and creates a first set of objects in a first structure based on the data. The system further creates, contemporaneously with the creation of the first set of objects and based on the first set of objects in the first structure, a second set of objects in a second structure, where the second set of objects is optimized for use by the specialized processing unit, and stores the first and second sets of objects in the memory. The specialized processing unit executes an algorithm based on the second set of objects.

A method implemented by one or more computers may include receiving data for graphical rendering and distributing a first portion of the data to a first computation process. The method may further include distributing a second portion of the data to a second computation process, where the second computation process is different than the first computation process, creating a first object subtree via the first computation process based on the first portion of the data, and creating a second object subtree via the second computation process based on the second portion of the data. The method may further also include assembling an object tree via a third computation process based on the first object subtree and the second object subtree and rendering a graphical scene based on the assembled object tree.

A system creates a first set of objects in a first structure that describe a graphical scene. A second set of objects is created in a second structure based on the first set of objects in the first structure. The system also performs one or more of the following: i) converting coordinate values in a first coordinate system to coordinate values in a second coordinate system, ii) converting color values in a first color space to color values in a second color space, and/or iii) converting data having first data types or formats to data having second data types or formats, where the first data types or formats are different than the second data types or formats. The system further associates the converted coordinate values, color values and/or data types or formats with the second set of objects and enables a graphical processing unit to use the second set of objects for rendering the graphical scene.

A system stores a first object tree that describes a graphical scene in memory and creates a second object tree based on the first object tree, where the second object tree is optimized for use by a graphics processing unit (GPU) to render a graphical scene. The system receives indications of one or more changes associated with the first object tree and traverses the first object tree to make the one or more changes to the first object tree and to generate a composite command for use in making corresponding changes in the second object tree. The system executes the composite command to make the corresponding changes in the second object tree.
