Loaded model doesn't display until window resized

[morphace]

Hi,

I load a model (STL file), but it's only displayed when I resize the browser window. I inspected the elements and saw that the canvas height is 0 intially, although I set the width to 100% and the height to 100em.

Thanks,
Markus

I have the same issue, still looking for a solution.

Any news on this one?

[morphace]

by the way: it's not related to the fact that I'm loading an STL file, happens with a simple cube as well...

ok, I have found what causes the problem: if the scene is not initially visible (for example sitting on a tab), the problem occurs. If I put the scene on the first tab (it will then be displayed initially) everything is fine.

Any Idea what could be the reason?

Hey, sorry for the delay on this. Would you mind preparing a minimally reproducible example? Preferably using Glitch or something similar? Here's a starter example on Glitch.

@morphace I hope this is the issue you were facing,
@BrainBacon I just created Glitch to give you an idea as I am facing the same issue.

So I am providing the editable link that you can run in separate screen to track the elements.

Before I start, Thanks for providing us with such a wonderful package.

So the issue is, I am trying to make the <div> appears when a button is clicked by a user.
To accomplish this, I hide the div with "display: none;"
and when the button is clicked, this display: none will be changed to "display: block;" which will now be visible on the screen.
However, by doing this, the width and height is fixed at 0px and to fix this, I have to either press F12 or resize the window just like @morphace mentioned.

Could this be a bug with the package?

This is what it looks like before clicking the button (<div> is hidden)

This is what it looks like after clicking the button (

is showing now)

This is what happens after we resize window or press F12

I assume it because the canvas is not following its parent's width and height?

@SnowNooDLe many thanks for the details. I'll try to carve out some time to take a look soon.

我觉得只是因为vue操作虚拟dom导致的，因为很多选项卡默认只会加载第一个选项，当你点击第二个点的时候他才开始加载第二个，很多类似的数据可视化组件有这种问题比如echarts，我建议在vue中使用this.$nextTick，等待dom完全加载出来之后在渲染
