Key Features of Cumulia ORE​

Rendering Performance​

Cumulia ORE optimizes the rendering pipeline to achieve ultra-fast browser-based rendering speeds and realistic image quality. Even in complex 3D scenes, it ensures smooth operation. For instance, in a model with over 8,000 parts and approximately 30 million facets, the engine can achieve rendering efficiency of 30 FPS in the browser, providing real-time rendering performance.

Programming Features​

  • Declarative API Design: Simplifies the process of building rendering scenes with a declarative approach, resulting in cleaner and more maintainable code.
  • Memory Management: Automatically handles memory allocation and release, effectively preventing memory leaks and ensuring safe and reliable code.

Rich Interfaces and Tools​

To further enhance its 3D rendering capabilities, ORE integrates a variety of plugins, including geometry libraries, material libraries, locators, and selectors, catering to the needs of engineering design, analysis, and manufacturing scenarios.

Overview of ORE Modules​

As a 3D rendering engine, ORE's core functionality includes organizing 3D scene trees, optimizing rendering queues, and constructing an efficient rendering pipeline. Its plugin-based architecture allows for functionality expansion. Below is an introduction to its key modules:

Material​

Provides commonly used materials such as Phong, Gouraud, Headlight, PBR, cartoon, and sprite materials. These materials are easy to use, requiring only configuration parameters from the user. The system ensures minimal shader generation during material creation, reducing GPU resource consumption and accelerating rendering. The shaders for lighting models in this library are also optimized for performance.

Postprocessing​

The postprocessing module offers 2D image processing capabilities, including Gaussian blur, edge detection, dilation, and other effects. These functions allow users to enhance and manipulate images for desired visual effects.

Color​

Includes color-related components for generating contour plots, converting color formats, and randomly generating colors with different hues. It also provides various color templates for simulation contour plots.

Geometry​

The geometry module is essential for interacting with complex industrial models. It offers a rich set of geometric primitives, from basic shapes (e.g., boxes, spheres, cylinders) to more complex multi-faceted and irregular geometries.

Selector​

Enables users to select specific elements in the rendering environment. It supports various selection options, including selecting entities, faces, edges, and points in the scene. Users can also select individual points or vertices by specifying coordinates or vectors, or perform fragment selection to target specific pixels or fragments.

In addition to single-element selection, the selector module supports penetration selection for entities, faces, edges, and points, allowing users to select elements located behind or intersecting with other objects in the scene.

Locator​

A set of tools for precise positioning, offering various types of locators to determine the position, orientation, and geometry of objects in the scene. These include linear locators, arc locators, position locators, orientation locators, geometric locators, rectangular locators, cylindrical locators, and spherical locators.

Manipulator​

Supports input recognition and interaction control for various devices. It translates user operations from devices such as a mouse, touchscreen, or 3D mouse into camera view changes, enabling intuitive control of the graphical interface.

Camera​

Provides extensive camera transformation capabilities, allowing users to easily control the view using a mouse or 3D mouse. Whether rotating around objects, zooming in on details, panning the scene, fitting the view to objects, or resetting to the initial position, the camera module meets all visualization needs.

Annotator​

This module allows users to enhance the visual representation of objects or scenes by adding annotations. Users can add high-quality text and icons to provide additional information or mark objects.

CAE Visualization​

Encapsulates various data filtering functions from VTK, such as Slice, Clip, IsoVolume, and Geometry. It offers rich visualization methods, including streamline animations, particle animations, and 3D arrows.

Debugger​

The debugger module is a tool for monitoring and analyzing GPU resource consumption. It enables users to track and measure GPU usage during rendering, providing valuable insights into rendering pipeline performance and efficiency.
