The previous tip showcased a command that is available in Civil 3D that lets you find the closest distance between 2 objects and even draws a line at the closest points. 3D physics engines provide collision detection algorithms, most of them based on bounding volumes as well. The objects may be geometric shapes or physical particles with well defined boundaries. The previous tip showcased a command that is available in Civil 3D that lets you find the closest distance between 2 objects and even draws a line at the closest points. The distance of closest approach is sometimes referred to as the contact distance. In computer graphics the Hausdorff distance is used to measure the difference between two different representations of the same 3D object particularly when generating level of detail for efficient display of complex 3D models. I want a sensor that reads the position of another sensor (the same type) in a 3D space (xyz vectors), and measures the resultant distance between the sensor and itself. Say a object which (in your case : ball) is say 5 cm in real world is represented using 30 pixels, then the distance between object which is 300 pixels on image can be calculate as (300 * 5 / 30). // Vary the parameters below to // get different control effects. These objects could be polygons (in 2D) or polyhedra (in 3D). Depth perception is the ability to perceive the world in three dimensions (3D) and to judge the distance of objects.
