Pass vec4 to a fragment wgsl

[eduardfossas]

Hello, I am following your examples in the book and the videos on youtube and I see you decided to go for a template string inside a typescript file instead of using wgsl extension. I have two questions regarding this:

• Is there a performance impact on doing so? Does it decrease the performance of WebGPU using a template string instead of a .wgsl file?
• How can you pass a vec4 from the pipeline to a fragment wgsl shader?

Thank you very much for sharing your experience.

no performance impact. wgsl file will be converted to string in the pipeline. starting from video series 42, I started to use wgsl extension to write shader code because it it easier to code that the string.

use uniform buffer to pass vec4 to shader.
