GLTF

You can load .glb/.gltf models with the built-in <gltf> component:

<template>
    <TroisCanvas>
        <gltf src="/your/model.glb"/>
    </TroisCanvas>
</template>

A GLTF ends up being added to the scene as a Three.js Group, so you can change all Object3D properties as if the <gltf> were a <group>:

<template>
    <TroisCanvas>
        <gltf 
            src="/your/model.glb" 
            position-z="-10" 
            scale-y="5"
        />
    </TroisCanvas>
</template>
