Web 3D Viewer Component

Step-up solution for bringing your CAD products to a website

Keeping up with two modern trends such as immersive computing and migration from on-premise to web, Open Cascade offers a unique development package of software components for short-time creation of 3D-rich web applications — Web 3D Viewer, which is a part of  Open Cascade Platform.

The package consists of two components:

• WebGL 3D viewer — the component responsible for CAD rendering and visualization in a web,
• Presentation Generator (BSON generator) — the component responsible for conversion of CAD files to internal binary presentation format (BSON) that can be displayed in a web browser with help of WebGL 3D viewer component.

Standard functionality* included into Web 3D Viewer:

• Navigation and rotation
• Standard views and various display modes
• Measurements
• Annotations
• Clipping planes and capping
• Exploded view
• Snapshots
• Object browser, synchronization of the selection between browser and 3D view
* Some additional functionality can be provided as a specific development based on other Open Cascade Platform components.


Start your web project with a solid basis or finish a puzzle with a missing piece:

• Create a stand-alone solution to view, analyze and share CAD models online
• Enrich your website with an interactive 3D viewing capacity
• Build in a 3D viewing capability into existing web-based solution or application

What makes Web 3D Viewer stand out:

• Apart from a simple viewing capability you receive a set of specific engineering-oriented features needed for CAD models analysis
• You make one-time payment for the development toolkit: no subscriptions and prolongations are required
• Time-proven expertise and ready-to-use development tools to customize your future web viewer solution
• Unlimited number of models and storage – we offer you flexibility and scalability from the very beginning

Key advantages for developers:

• Compatible with both WebGL 1.0/2.0
• JavaScript API layer offers a subset of functions for scene scripting
• Three.js renderer- display of custom actors
