3D convex lens projection simulation method and terminal

According to the 3D convex lens projection simulation method and the terminal provided by the invention, the convex lens body, the light source and the light screen are created in the 3D scene, the two cameras with opposite shooting directions are arranged at the center of the convex lens body, and the images shot by the two cameras are respectively drawn into the created positive material and negative material, so that the projection simulation of the 3D convex lens is realized. And subsequently, verifying the effectiveness of imaging among the light source, the convex lens and the light screen by acquiring the directions of the light source and the light screen, acquiring the positions of the light source and the light screen and the distance between the light source and the convex lens body, and setting a blurring effect and a zooming effect for the positive material or the negative material on which the image is drawn according to an imaging principle. In the whole process, the projection imaging effect o
