How to resize the thickness of the line of the camera frustum?

Hello author~ Is there a way to adjust the thickness of the camera line as sometimes the lines of the camera are too thin which makes them less visible in the scene.

I noticed that the camera is automatically bolded when you click on it, but I didn't find the corresponding code, looking forward to your reply!

Hi, this is unfortunately hardcoded as scale * 0.03 here:

viser/src/viser/client/src/ThreeAssets.tsx

Lines 440 to 442 in 3d30259

	<cylinderGeometry
	args={[props.scale * 0.03, props.scale * 0.03, 1.0, 3]}
	/>

We could expose an argument for configuring this. If you have time for a PR this would be appreciated!

If you're interested in the bold/outline effect, you could search based on OutlinesIfHovered. Here's where it's added for line segments we use for the camera frustums:

viser/src/viser/client/src/ThreeAssets.tsx

Lines 511 to 517 in 3d30259

	<Instance
	position={midpoint}
	quaternion={orientation}
	scale={[1.0, length, 1.0]}
	>
	<OutlinesIfHovered creaseAngle={0.0} />
	</Instance>
