Pointillism is actually a kind of impressionism. Not all stippling works are impressionist works. Different from other impressionist painters, he thinks that his pictures have more rational arrangement and design while studying the color of light and shadow, so the difference between him and other impressionist painters is that he is more rational. Unfortunately, he only lived to be 3 1 year old, but he did it to the extreme. So he can achieve the same achievements as Matisse who outlived him. Personal views need to be corrected.
