Look-ahead axis data calculated from the CNC controller enables in-time collision avoidance. Search form. Collision detection in real-time rendering is used in a variety of fields, such as CAD, simulations, robotics and games. Further, the information provided by the collision detection approach should allow for an ef-ficient and physically-correct collision response. Collision Detection - Circles, Rectangles and Polygons. Without collision detection, it doesn't seem reasonable to have collision avoidance because there wouldn't be anything to avoid (in the robot's scope). This scheme makes the collision detection e ectively transparent to the application. Collision detection is the computational problem of detecting the intersection of two or more objects. Collision detection between objects in a scene needs to determine whether objects collide. I could never understand why flash didn't do a vector based collision detection, or a collision detection that returned more than true or false. Nichols said the technological advancement represented by large-animal detection is the combination of camera recognition, analysis, processing and database that triggers the system. He called this "geometry free"collision detection because he doesn't use any geometry for this project, but only attraction behaviour. Figure 1 gives an overview of our collision detection process and illustrates how the proposed method fits the GPU stream architecture. Collision Detection. It's something we've considered, but making all the objects in the X-Plane world solid would be very expensive for your computer's processing and graphics power. Such actions require fast and accurate collision detection between the geometric representations of both the robot(s) and objects in the scene. Being a scalable and promissing technique, Image-based collision detection seems to be a plausible alternative to the classical approaches.
