print farms, product creators, and online stores that want to present 3D models in an interactive viewer.<\/p>\n\n<p>The plugin focuses on realistic presentation of FDM 3D prints. You can create reusable filament appearances, combine multiple colors, adjust surface properties and lighting, and let visitors inspect the model directly in the browser.<\/p>\n\n<p>It also works as a general-purpose 3D model viewer when you do not need filament-specific styling.<\/p>\n\n<h4>INTERACTIVE 3D MODEL VIEWER<\/h4>\n\n<p>Display models directly in WordPress without requiring visitors to install additional software.<\/p>\n\n<ul>\n<li>Support for STL, standard 3MF, GLB, and GLTF files.<\/li>\n<li>Mouse, touch, and keyboard-friendly controls.<\/li>\n<li>Rotate, zoom, and pan around the model.<\/li>\n<li>Optional automatic rotation.<\/li>\n<li>Fullscreen mode.<\/li>\n<li>Automatic model centering and camera fitting.<\/li>\n<li>Responsive layout for desktop, tablet, and mobile screens.<\/li>\n<li>Multiple independent viewers on the same page.<\/li>\n<li>Lazy loading for improved page performance.<\/li>\n<li>Optional fallback image.<\/li>\n<li>Reduced-motion support for visitors who prefer less animation.<\/li>\n<\/ul>\n\n<h4>REALISTIC FILAMENT APPEARANCES<\/h4>\n\n<p>Create reusable appearances that help models resemble real printed objects instead of plain 3D meshes.<\/p>\n\n<ul>\n<li>Single-color materials.<\/li>\n<li>Two-color and three-color combinations.<\/li>\n<li>Gradient color layouts.<\/li>\n<li>Rainbow color layouts.<\/li>\n<li>Layered color simulation with configurable band height.<\/li>\n<li>Natural layer variation and softened color boundaries.<\/li>\n<li>Custom roughness and metalness.<\/li>\n<li>Adjustable opacity and transparency.<\/li>\n<li>Surface styles such as matte, glossy, silk, metallic, satin, pearlescent, glitter, and more.<\/li>\n<li>Configurable environment reflections.<\/li>\n<li>Per-material lighting and exposure settings.<\/li>\n<li>Live 3D preview while editing an appearance.<\/li>\n<\/ul>\n\n<h4>APPEARANCE LIBRARY<\/h4>\n\n<p>Manage filament appearances from one place and reuse them across models.<\/p>\n\n<ul>\n<li>Create and edit an unlimited number of appearances.<\/li>\n<li>Search and select available appearances inside the viewer.<\/li>\n<li>Publish only the appearances you want visitors to use.<\/li>\n<li>Restrict a shortcode to selected appearances.<\/li>\n<li>Preview material changes immediately in the administration area.<\/li>\n<\/ul>\n\n<h4>LIGHTING AND PRESENTATION<\/h4>\n\n<p>Fine-tune how each model is presented.<\/p>\n\n<ul>\n<li>Adjustable key, fill, and ambient lighting.<\/li>\n<li>Exposure controls.<\/li>\n<li>Configurable viewer background.<\/li>\n<li>Optional transparent background.<\/li>\n<li>Viewer height and presentation options.<\/li>\n<li>Auto-rotation and fullscreen controls.<\/li>\n<\/ul>\n\n<h4>SHORTCODE SUPPORT<\/h4>\n\n<p>Insert a viewer into posts, pages, templates, or compatible page builders with the included shortcode.<\/p>\n\n<p>Use a Media Library attachment:<\/p>\n\n<pre><code>[ds82_3d_print_showcase model_id=\"123\" height=\"600\"]\n<\/code><\/pre>\n\n<p>Use a direct model URL:<\/p>\n\n<pre><code>[ds82_3d_print_showcase model_url=\"https:\/\/example.com\/model.stl\"]\n<\/code><\/pre>\n\n<p>When the <code>material<\/code> parameter is omitted, all published appearances are available. To limit the selector, provide one or more internal appearance identifiers:<\/p>\n\n<pre><code>[ds82_3d_print_showcase model_id=\"123\" material=\"internal:az1,internal:az2\"]\n<\/code><\/pre>\n\n<h4>INTEGRATIONS AND EXTENSIBILITY<\/h4>\n\n<p>3D Print Showcase includes an extensible architecture for optional integrations and add-ons.<\/p>\n\n<ul>\n<li>REST API endpoints for supported plugin functionality.<\/li>\n<li>Material provider registry for compatible integrations.<\/li>\n<li>Architecture prepared for WooCommerce use cases.<\/li>\n<li>Architecture prepared for Advanced Custom Fields workflows.<\/li>\n<li>Translation-ready codebase.<\/li>\n<li>Bundled Czech, Slovak, German, and Russian translations.<\/li>\n<\/ul>\n\n<p>Some integrations may require a separate compatible add-on.<\/p>\n\n<h4>PRIVACY AND EXTERNAL SERVICES<\/h4>\n\n<p>The plugin does not load executable JavaScript or CSS from a third-party CDN. Required viewer libraries are bundled locally with the plugin.<\/p>\n\n<p>A remote model is requested only when an administrator or content author explicitly configures a direct external model URL. In that case, the visitor's browser connects to the selected model host as necessary to display the model.<\/p>\n\n<p>No account with an external service is required to use the core plugin.<\/p>\n\n<h4>PLANNED ADD-ONS<\/h4>\n\n<p>We are actively developing additional tools for 3D printing websites and stores.<\/p>\n\n<h4>Calculator<\/h4>\n\n<p>A planned pricing and print estimation add-on for calculating material usage, print time, weight, production costs, and custom pricing rules.<\/p>\n\n<h4>Configurator<\/h4>\n\n<p>A planned product configuration add-on that will allow customers to choose model appearances, filament materials, colors, and available product options before ordering.<\/p>\n\n<h4>HAVE AN IDEA FOR A NEW FEATURE?<\/h4>\n\n<p>We welcome practical feature requests from makers, designers, print farms, and online stores.<\/p>\n\n<p>If you need another model format, material effect, integration, workflow, or add-on, contact us through <a href=\"https:\/\/wpresstech.cz\/\">WPressTech.cz<\/a>.
