Native html scroll and @tresjs/cientos Html component behaviour

estubmo opened this issue · comments

Describe the bug

Say I want to have scrollable native html on my page, while keeping the canvas static while also using @tresjs/cientos Html component on some meshes in the scene. (Not using ScrollController)

I would like for the Html on the box to stay relative to it's Mesh while scrolling.

As of now, this Html will also scroll with the page.

Reproduction

Steps to reproduce

Run the sandbox and scroll.

There are two text elements.

<div
    :style="{
      height: '200vh',
      display: 'flex',
      alignItems: 'center',
      justifyContent: 'center',
      fontSize: '5rem',
    }"
  >
    This should scroll
  </div>

and

<TresMesh :position="[1, 1, 1]">
      <TresBoxGeometry />
      <TresMeshNormalMaterial />
      <Html
        center
        transform
        :distance-factor="4"
        :position="[0, 0, 0.65]"
        :scale="[0.75, 0.75, 0.75]"
      >
        <div>
          <p>This should not scroll</p>
        </div>
      </Html>
    </TresMesh>

I expect the first element to scroll, and the second to stay.

Code of Conduct

Hey @JaimeTorrealba could you support @estubmo here please?

unm, this is a good one. The problem here is that the HTML component doesn't create a 3D object, basically fake it, that's the reason why follow the natural flow.
We could add a fixed prop (or similar) to allow user do this, because now the styles are inline, so... No CSS classes will overwrite this.

Just for question, why not create a normal CSS element (outside TresJs) and apply position fixed? I know, it is just a workaround, but why not? :)
