Fast and Reliable Collision Detection Between 3D Shapes
The OPEN CASCADE Collision Detection SDK provides powerful algorithms to detect collisions, proximity violations, and clashes between pairs of 3D shapes. This specialized component enables fast shape-shape collision analysis between OPEN CASCADE shapes positioned at arbitrary locations, making it ideal for CAD/CAM applications, robotic path planning, and virtual assembly verification.
Key Features
Comprehensive Detection Capabilities
The Collision Detection component offers:
- Collision Detection – Identifies contact points between shapes according to specified tolerance
- Proximity Analysis – Determines if shapes are near each other based on user-defined threshold
- Clash Analysis – Evaluates potential interference between moving components
- Detailed Results – Provides specific collision locations (points, triangles, or faces)
Advanced Technical Implementation
- Based on optimized Axis-Aligned Bounding Box (AABB) trees
- Works with triangle meshes bound to OPEN CASCADE shapes
- Adaptable to non-OPEN CASCADE mesh structures
- Independent positioning without AABB-tree recalculation
