Hi, I referenced the /cross_browser-master/client/fingerprint/texture/app.js file, but the susan model was not drawn successfully in the end. Can you help me check the specific reasons? #90

I am a developer and my business is risk control, can you add my WeChat? My WeChat ID is pdm_peng, I am also studying this recently, but I have not succeeded in drawing the texture
