Design and Application Research of Virtual Surveying and Mapping Mechanical Drawing Teaching Assistant System: Based on WebGL Technology
Due to the simplicity of traditional surveying and mapping teaching, students have low efficiency in surveying and mapping, making it difficult to effectively reconstruct three-dimensional models through two-dimensional drawings. The existing mechanical drawing teaching system lacks in-depth research on the mapping function of 2D to 3D space. To solve this problem, based on the WebGL technical framework and combined with the needs of teachers and students, the effectiveness method of 2D to 3D cognition is proposed, which breaks through the limitations of time and space. Through three.js framework and front-end technology, a virtual surveying and mapping teaching assistant system based on WebGL technology is developed. The results show that the accuracy of the system mapping model is better than that of the actual mapping model. Model projection drawing time (t1) and model measurement time (t2) are used to compare the mapping effects of the virtual group and the real group. In the Levene variance equality test, the P values of t1 and t2 are both greater than 0.05, indicating that the difference between the two groups of squares is equal. The P-values of Levene variance equality test for projection drawing score (f1) and measurement dimensification score (f2) are also greater than 0.05. The average score of the virtual group is higher than that of the real group, with an average satisfaction score of 1.16 points higher. In the future, the drawing calling function will be added on the basis of the part assisted drawing system to realize the intelligent generation and management of engineering teaching drawing. This research not only improves the teaching efficiency, but also realizes innovation and breakthrough in the application of 2D to 3D mapping function, showing its superiority in the teaching of mechanical drawing.
