Hi,

If I want to skillfully modify Vertex Shader and Fragment Shader and get the desired effect. What kind of learning process should I go through? Can you come up with a complete tutorial?

  This is a great question, thankyou for asking. 
  Rightware does not currently have any material that teaches users how to write shader code, as this is expected to be known before development as it is a very complicated topic. 
  
  However there are great materials that exist on the internet that are recommended:

  The following site called the book of shaders covers many of the basic topics required for writing shaders. Examples are provided, and are great way to start your journey into writing shaders. 
  https://thebookofshaders.com/
  
  There are also many youtube tutorials that exist please see the following;

  I hope this helps, and please post any examples you are looking to create, or have created and perhaps someone from the community can assist.

  Thank you for your reply. I want to draw a curve dynamically, and the amplitude of the curve moves all the time, just like an electrocardiogram.
