🚀 Introduction to Spline and Project Setup

The script begins with an introduction to Spline, a 3D software tool designed for embedding 3D scenes into websites. The author expresses excitement about teaching beginners how to use Spline for creating interactive web elements. The tutorial will focus on building a hero section for a water bottle company's website, featuring mouse-over animations. The author guides viewers through starting a new project in Spline, navigating the interface, and selecting a cylinder as the base for the water bottle model. Emphasis is placed on understanding the 3D workspace, manipulating the camera perspective, and the basic tools for creating and modifying 3D objects.


🛠️ Shaping the Water Bottle Model

This paragraph delves into the process of shaping the water bottle using Spline's modeling tools. The author demonstrates how to select and manipulate the top faces of the cylinder to create the bottle's body, using extrusion and scaling techniques to form the bottle's contours. The focus is on creating a realistic bottle shape with an open top and rounded bottom. The author also discusses the use of the subdivision modifier to smooth out the model and the importance of selecting the correct faces for manipulation to achieve the desired shape.


🔄 Creating the Bottle Cap and Material Application

The tutorial continues with the creation of the water bottle's cap. The author uses a similar approach to modeling, starting with a cylinder and refining its shape to fit atop the bottle. Attention is given to creating the cap's inner structure to ensure a proper fit with the bottle. Once the cap's shape is finalized, the author moves on to applying materials to the bottle and cap. This includes selecting a base color, adding layers for reflections and lighting effects, and using a bump map to create a subtle texture on the bottle's surface. The goal is to achieve a metallic appearance for the water bottle and its cap.


🖼️ Adding Details and Interactions

In this section, the author focuses on adding final touches to the 3D model, such as the company logo on the bottle and adjusting the materials' properties for a more realistic metallic look. The author also discusses the importance of blending modes and opacity to enhance the visual effect of the logo on the metallic surface. The paragraph then transitions into creating interactive elements, such as hover states for the bottle and cap, which will trigger animations when a user interacts with the web page. The author sets up these interactions in Spline and previews the effect to ensure a dynamic user experience.


🌐 Implementing the Spline Scene in Webflow

The final paragraph covers the integration of the Spline scene into a Webflow project. The author demonstrates how to import the Spline scene into Webflow using a provided link, allowing for the scene to be displayed within the web page. The author also explores additional export settings in Spline to customize the interaction experience, such as camera movement on hover. After implementing the scene in Webflow, the author shows how the animations work within the web page context and hints at the potential for further customization and interaction using Webflow's native tools. The tutorial concludes with an invitation for feedback and suggestions for future content.




Spline is a 3D software tool specifically designed for embedding 3D scenes in websites. It allows for the creation of interactive and visually appealing web content. In the video, Spline is used to build a dynamic hero section for a water bottle company's website, showcasing its capabilities for beginners who wish to learn about 3D integration in web design.

💡Hero Section

A hero section is a prominent part of a website, typically at the top, designed to attract attention and make a strong first impression. In the context of the video, the hero section is being created for a water bottle company and will feature interactive 3D elements built with Spline, enhancing user engagement.

💡3D Modeling

3D modeling is the process of creating a representation of a three-dimensional object using specialized software. In the video, the instructor demonstrates the basics of 3D modeling within Spline, starting from a simple cylinder to create a water bottle, which is central to the project's theme.

💡Webflow Integration

Webflow integration refers to the compatibility of Spline with Webflow, a web design and development platform. This integration allows for the seamless implementation of 3D scenes created in Spline into Webflow websites, as shown in the video where the Spline scene is embedded into a Webflow project.


A cylinder is a 3D geometric shape with straight parallel sides and a circular or oval cross-section. In the script, the cylinder is the starting point for modeling the water bottle, demonstrating how to manipulate its dimensions and properties to achieve the desired form.


Extrusion in 3D modeling is the process of pushing a 2D shape into 3D space, creating a solid form. The video script describes the use of extrusion to form the top of the water bottle by pushing and scaling the selected faces of the cylinder.

💡Subdivision Modifier

A subdivision modifier is a tool in 3D modeling that increases the detail of a mesh by adding more vertices, edges, and faces. In the video, the instructor uses a subdivision modifier to smooth out the water bottle's surface, improving its visual appearance.

💡Material and Texture

Materials and textures in 3D modeling define the surface properties and visual appearance of an object. The video explains how to apply a material with a metallic look to the water bottle using a matcap layer and a bump map texture, adding realism to the 3D object.

💡Interaction Design

Interaction design involves creating elements that respond to user input, such as mouse movements or clicks. In the video, the instructor creates interactive states for the bottle and cap that change when the user hovers over them, adding dynamic elements to the web page.


Fresnel is a material property in 3D rendering that simulates the way light reflects off a surface at different angles, affecting the shininess and reflectiveness of an object. The script mentions using a Fresnel layer to add a metallic shine to the water bottle.

💡Bump Map

A bump map is a texture used in 3D rendering to simulate small surface irregularities, adding depth and detail to a material without changing its geometry. The video demonstrates applying a grass texture as a bump map to the water bottle to give it a textured metallic appearance.
