我想在多个图像上增强视频。所以我正在尝试使用多个图像实现第八墙图像跟踪增强。但我无法获得增强。我对图像目标有疑问。如果我在 html 中提到图像目标名称，那么它就可以工作。
<a-entity target-video="name: imageTargets; video: #alpha-video;" material="shader: chromakey; src: #alpha-video; color: 0.1 0.9 0.2" geometry="primitive: plane; height: 0.6; width: 1.38;"> </a-entity>
名称:imagetarget1(第 8 个墙壁控制台中的图像目标名称之一)
但是当我尝试使用多个图像时，它不起作用。 任何人都可以帮我解决这个问题。我已在第 8 个墙上控制台上传了 10 张图像，名称如下 - 'imagetarget1'、'imagetarget2'、'imagetarget3'、'imagetarget4'、'imagetarget5'、'imagetarget6'、'imagetarget7'、'imagetarget8'、'imagetarget9 ', 'imagetarget10' 。
AFRAME.registerComponent('target-video', {
schema: {
name: {
type: 'string'
XR8.XrController.configure({
imageTargets: ['imagetarget1', 'imagetarget2', 'imagetarget3', 'imagetarget4', 'imagetarget5', 'imagetarget6', 'imagetarget7', 'imagetarget8', 'imagetarget9', 'imagetarget10']
})
},
video: {
type: 'string'
},
},
init: function() {
const object3D = this.el.object3D
const name = this.data.name
object3D.visible = false
const v = document.querySelector(this.data.video)
const el = this.el
const showImage = ({
detail
}) => {
if (name != detail.name) {
return
}
v.play()
object3D.position.copy(detail.position)
object3D.quaternion.copy(detail.rotation)
object3D.scale.set(detail.scale, detail.scale, detail.scale)
object3D.visible = true
}
const hideImage = ({
detail
}) => {
if (name != detail.name) {
return
}
v.pause()
object3D.visible = false
}
this.el.sceneEl.addEventListener('xrimagefound', showImage)
this.el.sceneEl.addEventListener('xrimageupdated', showImage)
this.el.sceneEl.addEventListener('xrimagelost', hideImage)
}
