Description
Summary: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, 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 trend line. The trend line constitutes our bounding box. Now, our collision detection is based on three-dimensional objects, but not the simple line segment. Additionally, we can expand x, y, z in all vertices in proportion and achieve early warning mechanism in virtual reality.
