## Arcadium

Arcadium is an online 3D design environment aimed at homeowners, interior designers, architects, and real estate professionals who need to communicate spatial ideas quickly. You drag walls, doors, windows and furniture into place using dynamic parametric components and alignment tools, work with real measurement units, and switch between 2D plan and 3D view. Because it runs entirely in the browser, there is nothing to install.

The distinguishing feature is the AI layer. You take any camera view from your 3D scene and ask the tool to render it in a different style — photoreal, alternate interior direction, sketch or watercolor — which is useful for client presentations when a raw 3D view is too technical. There is also a workflow where you describe your space to ChatGPT, Claude or Gemini and then refine the generated layout inside Arcadium.

Arcadium also handles the paperwork side of design: outline mode, cross sections and elevations let you turn a model into plans that builders and planning authorities can read, and everything can be shared through a URL instead of exported files. The site lists user testimonials from architects, interior designers and homeowners, including one describing use for securing planning permission. It is free to start, with paid tiers for additional capability.

**Pricing & Plans:** Freemium: free to start with no download, with paid plans for additional features. Check the pricing page for current plan details.

- **Easy 3D modelling:** Build walls, doors, windows and rooms with dynamic parametric components and alignment tools, using precise measurements.
- **AI visualization:** Render any 3D view as photoreal, restyled interiors, sketch or watercolor for client-ready presentations.
- **Floor plans and elevations:** Switch to outline mode and generate cross sections and elevations suitable for builders and planning applications.
- **Built-in object library:** Furnish designs from a free 3D object library, then adjust materials, colors, labels and dimensions.
- **Shareable URLs:** Send stakeholders a link to the live 3D scene, floor plan or walkthrough instead of exporting files.

**Strengths:** Free to start with no installation or plugins; AI visualizations turn rough models into presentable images; Floor plan, elevation and outline exports suit formal planning use; Shareable links make client feedback simple

**Limitations:** Free tier limits some advanced features; Not a substitute for CAD-grade construction documentation; Browser performance depends on scene complexity

## Spline

Spline brings 3D design into the browser so designers, developers and marketers can build interactive 3D without a heavyweight desktop pipeline. The editor covers primitives, booleans and sculpting, plus 3D generation, layered materials, lighting and post-processing. Animation and interaction are handled through states, keyframes, events and physics, and the whole file runs with real-time performance.

A standout feature is agent collaboration: you can connect assistants such as Claude, ChatGPT, Cursor or Codex through Spline MCP so an agent can read and write to the live scene, then hand it back to your team for refinement in the very same file. Because everything the agent produces is a regular Spline object, teammates can select, restyle, animate or undo it by hand at any point.

Publishing targets the modern web and mobile stacks. You can share a link, embed a viewer or export code for web (WebGPU/WebGL), add a native SwiftUI or Metal view for Apple apps, or build for Android with Vulkan and Jetpack Compose. Spline is used for interactive product design, brand and marketing pages, immersive experiences, gamified sites and education.

**Pricing & Plans:** Spline offers a free tier to start building in 3D, with paid plans for individuals and teams and a dedicated Enterprise offering. Exact seat and feature limits per tier are listed on the Spline pricing page.

- **In-browser 3D editor:** Model with primitives, booleans and sculpting, and use 3D generation to create objects from prompts.
- **Materials, lighting and post-processing:** Apply layered materials, lights and post-processing effects to give scenes a polished, production-ready look.
- **Animation and interaction:** Build interactivity using states, keyframes, events and physics so scenes respond to scroll, hover and other triggers.
- **Agent collaboration over MCP:** Connect AI coding agents to read, write and frame the live scene, then refine the same file by hand with your team.
- **Ship to web, iOS and Android:** Publish a link, embed a viewer, export code for the web, or create native Apple and Android views and builds.

**Strengths:** Runs entirely in the browser, so there is no heavy install or setup barrier; Real-time collaboration and agent workflows keep designers and developers in one shared file; One scene publishes to web, iOS and Android with platform-native renderers; Broad feature set spanning modeling, materials, animation, physics and interaction

**Limitations:** Advanced 3D work may still require a learning curve for newcomers; Performance and export options depend on the device and platform you target; Team and enterprise capabilities sit behind paid tiers
