Build unique 3D user experiences with Phasma3D Viewer
Embedding a 3D model into your website is as simple as the markup below. To help with that, the <phasma-viewer> web component lets you declaratively add a 3D model to a web page, while hosting the model on your own site.
Step 1: Include the JS Library
Include the "Phasma3DViewer" library in the <head> section of your HTML file: 
<head>
<!-- Other head elements -->
<script type="module" src="https://phasmatic.com/viewer/dist/phasmaviewer.js">
</script>
</head>
Step 2: Add the Element
Create a <phasma-viewer> element in the body of your HTML file. Set the src attribute to the path of your 3D model file. Here's a basic example: 
<body>
<!-- Other HTML content -->
<phasma-viewer 
  src="path/to/your/model.glb"
  poster="path/to/your/poster_image.jpg"
  alt="alternative text explaining the 3D model"
  camera-enable-controls
  background-color="#ffffff"
>
</phasma-viewer>
<!-- Other HTML content -->
</body>
Next, configure it's styling as a regular HTML Element: 
phasma-viewer {
  width: 512px;
  height: 512px;
}
Step 3: Customize and Add Options
The <phasma-viewer> supports various attributes to customize its behavior. In the example above, we've added the following attributes:
  • src: Set this to the path of your 3D model file.
  • poster: Displays an image instead of the model.
  • alt: Provide a text description for accessibility.
  • camera-controls: Allows users to interact with the model using mouse and touch input.
  • background-color: Sets the background color of the viewer.

Step 4: Test Locally
Save your HTML file and open it in a web browser to test the embedded 3D model locally. Ensure that the model is displayed correctly and that the interactive features work as expected.
Step 5: Deploy to Your Website
Upload your HTML file and the 3D model file to your web server or hosting provider. Make sure the file paths in your HTML code match the actual paths on your server.
Step 6: API Documentation
Step 6.1: Enable Animations on 3D Assets
To enable a specific animation of your model by clicking a button, you have to include JavaScript directly within the HTML file using the <script> tag and follow the corresponding calls. Here's a basic example: 
// Inline JavaScript at the end of the body section
const phasma_viewer = document.getElementById("phasma_id");
const animation_btn = document.getElementById("animation_btn");
animation_btn.onclick = () => {
  let animation_name = "ANIM_TRACK_NAME";
  phasma_viewer.triggerAnimation(animation_name);
};
Step 6.2: Select Variant on 3D Assets
To enable a specific color variant of your model by clicking a button, you have to include JavaScript directly within the HTML file using the <script> tag and follow the corresponding calls. Here's a basic example: 
// Inline JavaScript at the end of the body section
const phasma_viewer = document.getElementById("phasma_id");
const variant_btn = document.getElementById("variant_btn");
variant_btn.onclick = () => {
  let variant_name = "VARIANT_NAME";
  phasma_viewer.triggerVariant(variant_name);
};
Step 6.3: More options
Refer to the following table for a full list of API options you can use to customize the interactive behavior of the 3D viewer.
METHODS DESCRIPTION
triggerVisibility(name: string, visible: boolean) Enable or disable the visibility of a geometry mesh by name.
availableVariants() Reports an array of strings, corresponding to variants in the loaded model that can be triggered.
triggerVariant(name: string) Displays a model variant by name.
availableAnimations() Reports an array of strings, corresponding to animations in the loaded model that can be triggered.
triggerAnimation(name: string) Plays the animation by name.
triggerAnimationPause(name: string) Pauses the animation by name.
triggerAnimationStop(name: string) Stops the animation by name.
availableAnnotations() Reports an array, corresponding to annotation information in the loaded model that can be triggered to enable camera movement, init mesh animation or alter color variant.
triggerVisibilityAnnotations() Enable (or disable) the visibility of all available annotations.
onLoadPromise() Returns a Promise that is resolved when the 3D asset is loaded.
Step 7: Add Annotations
Annotations refer to interactive elements that can be added to 3D scenes to provide additional information or interactivity to users. These annotations can include text labels or clickable areas that trigger actions when interacted with. There are four predefined trigger actions that can be applied on click:
  • Navigate to a camera view.
  • Enable a specific animation.
  • Change a specific color variant.
Please note that all available actions can be either enabled all at once in a single interaction or completely omitted. To add annotations to a 3D model, you typically use the <phasma-viewer> and include annotations as part of the model's attributes. Here's a basic example: 
<phasma-viewer  
.
.
.
>
<button
slot="annotation-default-1"
data-position="0.0 0.0 0.0"
data-normal="-0.0 1.0 0.0"
data-camera="0.1 0.3 0.4"
data-animation="ΑΝΙΜ_TRACK_NAME"
data-variant="VARIANT_NAME"
data-visible="true">
1
</button> 
</phasma-viewer>
where, <button> tag defines a clickable hotspot with a text label. slot assigns the button to a specific hotspot slot on the model. data-position and data-normal attributes specify the position and orientation of the hotspot relative to the model. Additionally, you can use more attributes to handle events triggered by user interactions with the annotations. Specifically, data-camera specifies the final camera position, data-animation specifies the animation name and data-variant specifies the color variant of the model. Inside the <button> tag, you can include any content you want to display when the hotspot is clicked, such as additional text or images. Annotations can be further customized with CSS to control their appearance and behavior.
