Three-dimensional characterization method for rocket engine test process system

The invention discloses a three-dimensional characterization method for a rocket engine test process system. The system comprises an engine part model class and a sensor class. The data of the sensorclass is transmitted to the engine part model class through an interpolation algorithm, and the three-dimensional physical field distribution display of an engine part model is realized through texture rendering. Attributes of an engine part model class are set, the functions of scaling, rotating, moving, hiding and subdividing the model are achieved, attributes of a sensor class are set, the functions of hiding and changing color display of a sensor are achieved, different colors represent different sensor classes, and the size of a color bar ruler controls color distribution of the engine part model. By adopting a spatial three-dimensional coordinate system, a set of complete or local three-dimensional process display system can be built. 本发明公开了一种火箭发动机试验工艺系统三维表征方法，包括发动机部件模型类和传感器类，通过插值算法，将传感器类的数据传递到发动机部件模型类中，经过纹理
