Collision detection in Vega Prime is based on the simple line segment, and collision detection based on bounding box is not realized. By studying the composition of three-dimensional object based on Oriented Bounding Box (OBB), we define a collision detection class, which inherits from vpIsector. After finding out all vertices of geometry in object, we connect these vertices one by one and constitute a tend line. The trend line constitutes our bounding box based on OBB. Now, our collision detection is based on three-dimensional objects, but not the simple line segment. At the same time, we can control the efficiency of collision detection by increasing or decreasing the number of collision lines on the actual demand. Additionally, on this basis, we have made the further application. By adjusting parameter, we can get a bounding box with early warning mechanism or collision tolerance.

This paper presents a novel method to tie geometric boundary representation (BREP) to voxel-based collision detection for use in haptic manual assembly simulation. Virtual Reality, in particular haptics, has been applied with promising results to improve preliminary product design, assembly prototyping and maintenance operations. However, current methodologies do not provide support for low clearance assembly tasks, reducing the applicability of haptics to a small subset of potential situations. This paper discusses a new approach, which combines highly accurate CAD geometry (boundary representation) with voxel models to support a hybrid method involving both geometric constraint enforcement and voxel-based collision detection to provide stable haptic force feedback. With the methods presented here, BREP data can be accessed during voxel-based collision detection. This information can be used for constraint recognition and lead to constraint-guidance during the assembly process.

In order to solve the problem of space-time conflict in multi route planning, this paper proposes a space-time conflict detection method based on bounding box. The main research contents include: dividing each route into a limited number of road sections, each road section uses a bounding box to represent the space occupied by the target in the period of time, and then using OBB collision detection method to judge whether there is different bounding box overlap in the same space at the same period of time, so as to judge whether there is a space-time conflict. In addition, calculating the distance among road sections to exclude road sections where conflicts are unlikely to occur before detection. The feasibility of the conflict detection method is verified by experiments on a multi route planning case.
