You can also create your own Loading View

For example:

  • In your HTML
  <!-- Loading DIV -->
  <div id="loadingDiv">
      <p id="loadingText" class="font-weight-light">L O A D I N G</p>
      <span class="loader"></span>
  </div>
  • Format your Loading DIV in your CSS
/* Loader */
#loadingDiv {
    z-index: 200;
    position: absolute;
    width: 100%;
    height: 100%;
    background: #8bb4ff; /* Old browsers */
    background: -moz-linear-gradient(top, #8bb4ff 0%,#ff60f2 100%); /* FF3.6-15 */
    background: -webkit-linear-gradient(top,  #8bb4ff 0%,#ff60f2 100%); /* Chrome10-25,Safari5.1-6 */
    background: linear-gradient(to bottom,  #8bb4ff 0%,#ff60f2 100%); /* W3C, IE10+, FF16+, Chrome26+, Opera12+, Safari7+ */
    filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#FB7BA2', endColorstr='#FCE043',GradientType=0 ); /* IE6-9 */
    /* border: 25px solid rgb(255, 255, 255); */
    touch-action: none;
    -webkit-user-select: none; /* Safari */
    -ms-user-select: none; /* IE 10 and IE 11 */
    user-select: none; /* Standard syntax */
}

#loadingText {
    position: absolute;
    color: white;
    display: inline-block;
    box-sizing: border-box;
    text-align: center;
    font-size: x-small;

    width: 100%;
    top: 50%;
    left: 50%;
    height: 50px;
    transform: translate(-50%, -50%);
    margin-top: 40px;
    letter-spacing: 0.3rem;
    touch-action: none;
    -webkit-user-select: none; /* Safari */
    -ms-user-select: none; /* IE 10 and IE 11 */
    user-select: none; /* Standard syntax */
    /* animation: animText  6s ease infinite alternate; */
}

@keyframes animText {
    0% {
        letter-spacing: 0.2rem;
    }
    100% {
        letter-spacing: 0.4rem;
    }
}

.loader {
    position: absolute;
    top: 45%;
    left: 50%;
    transform: translate(-50%, -50%);

    width: 48px;
    height: 48px;
    display: inline-block;
    position: relative;
  }
.loader::after,
.loader::before {
    content: '';  
    box-sizing: border-box;
    width: 48px;
    height: 48px;
    border-radius: 50%;
    border: 2px solid #FFF;
    position: absolute;
    left: 0;
    top: 0;
    animation: animloader 2s linear infinite;
}
.loader::after {
    animation-delay: 1s;
}
  
@keyframes animloader {
    0% {
      transform: scale(0);
      opacity: 1;
    }
    100% {
      transform: scale(2);
      opacity: 0;
    }
}
  • And finally in your js code you can hide your Loading DIV when your model is loaded
setTimeout(() => {
    hideLoadingView();              
}, 1000);

// Hide Loading View
function hideLoadingView() {
    document.getElementById("loadingDiv").style.display = "none";
}
