CollisionDetection

OPEN CASCADE Collision Detection

OPEN CASCADE Collision Detection is a specialized component for fast detection of collision or proximity between pairs of shapes.

Overview

Collision Detection is a commercial component based on Open CASCADE Technology designed to detect collision (intersection) or proximity between two shapes. The fast shape-shape collision and proximity detection algorithm (called "Proxy") enables detecting collisions or proximity criterion violations between a pair of Open CASCADE shapes positioned at arbitrary locations.

Benefits

• Combines high performance in both collision and proximity modes with flexibility and ease of control
• Provides an efficient foundation for implementing various positioning techniques, including path walking for Coordinate Measurement Machines
• Allows easy adjustment of computation precision by changing the corresponding mesh deflection
• Features a convenient API for fast integration into existing applications, with easy connection to any particular GUI
• Requires no third-party licenses

Features

The Collision Detection component can:

Collision Detection

• Detect if shapes are in contact with each other according to a specified tolerance
• Provide detailed information about collision locations (points, triangles, or faces)

Proximity Detection

• Given a proximity value, detect if shapes are near each other
• Provide related locations (points, triangles, or faces) where proximity criterion is triggered

Technical Implementation

• Based on manipulating trees of Axis-Aligned Bounding Boxes (AABB) constructed around triangle meshes bound to Open CASCADE shapes
• Can be easily adjusted to accept non-Open CASCADE meshes
• Allows independent positioning of each shape in arbitrary locations without recalculation of AABB-trees of mesh triangles
• Precision defined by the corresponding mesh deflection, which can be easily adjusted
• Performance comparable to other open source and commercial collision detection solutions

Flexibility

• Works with a wide range of input geometry without strong restrictions
• No requirements for convexity, manifold shapes, or non-coplanar triangles that other algorithms might impose
