Abstract

The invention discloses a triangle intersection detection method applied to three-dimensional visual simulation of remote operation, and proposes a new triangle intersection detection algorithm for fine collision detection of three-dimensional graphic models. Compared with the traditional triangle intersection test algorithm, the present invention does not have the step of exchanging two triangles for recalculation, thereby saving a lot of calculation work by reusing the calculation results of the same triangle, and improving the speed of fine collision detection of 3D graphic models as a whole.

Description

technical field

[0001] The invention belongs to the field of three-dimensional simulation display of virtual reality and space teleoperation, and relates to a graphic collision detection method, in particular to a triangle intersection detection method applied to three-dimensional visual simulation of teleoperation. Background technique

[0002] Teleoperation plays an important role in the field of space offensive and defensive confrontation. Using space robots to complete various space tasks is a trend in space development. Technologies such as obstacle avoidance have extremely important application prospects. However, due to the existence of time delay, delayed feedback information such as vision and force sense cannot provide the operator with a real-time sense of presence, and it is easy to mislead the operator's operation behavior, which in turn affects the safe execution of teleoperation tasks.

[0003] The most important problem of teleoperation technology is to overc...
