Spline is a browser-based collaborative 3D design platform for authoring interactive scenes for websites, apps, and spatial presentations. Designers can build with 2D and 3D objects or import assets, then set cameras, lighting, layer-based materials, states, events, and actions. Its value is the authored real-time experience: an object can react to pointer, keyboard, scroll, or scene events before the scene is shared, embedded, or exported.
Spline is strongest when the deliverable is an interactive 3D experience, not simply a finished picture. A web or product designer can import a model, arrange a camera and lights, build layered materials, and connect object states to interactions such as hover, click, scroll, or keyboard input. The scene can then be embedded or integrated into a digital experience. RENDERCAD serves a different practical moment: take the strongest existing CAD viewport, Spline preview, product angle, or design screenshot and turn that fixed view into a polished photorealistic still. This avoids rebuilding geometry, material layers, and event logic when the brief calls for a concept board, stakeholder review image, presentation slide, or campaign visual rather than a live 3D interface.
Spline and RENDERCAD are complementary visual tools with different sources of truth. In Spline, the scene is the source of truth. Teams author objects, lights, cameras, material layers, animation, variables, and interactions, then maintain that scene for interactive web content, prototypes, explainers, or product storytelling. Spline can import common 3D assets as well as images, vectors, video, and audio, so it suits designers who need to compose and ship a responsive experience around those assets. Its interactive behavior remains valuable when people need to explore the scene or when a product site needs a real-time element.
Screenshot the CAD viewport you already have, render in the browser, and download a client-ready still or video without exports, plugins, or GPU setup.

Add, change, or remove referenced objects with the stroke of a brush.
RENDERCAD uses a maintained selection of image-generation models for different rendering tasks. Results can vary by model and input, so compare generated output with the source design before relying on geometry, materials, or dimensions.
| Feature | RENDERCAD | Spline |
|---|---|---|
| Engine | Generative AI | Real-time 3D scene editor and web runtime |
| Output | Images + Video | Interactive web embeds, hosted scene links, code exports, images, video, image sequences, and selected 3D or app exports |
| Resolution | HD / 4K | Image export resolution is selected in Spline and depends on the scene and export settings |
| Image Speed | Image renders complete in 60 seconds. | Real-time scene preview; image and video exports are prepared from the authored scene |
| Video Speed | Videos complete in 2-5 minutes. | Video is exported from an authored scene; it is not a one-click enhancement of a screenshot |
| Scene Set Up | No separate local scene | Create or import scene assets, then configure cameras, lights, material layers, animation, states, and event actions |
| Input | Screen Snip | Spline scenes, built-in objects, imported 3D assets, PNG or JPG images, SVG vectors, video, audio, and interaction settings |
| Materials | 2,600+ Textures | Layer-based materials with color, image, lighting, normal, gradient, glass, and other shading layers |
| Backgrounds | 1300+ Backgrounds | Tool-dependent |
| Conditions | 40+ Effects | Tool-dependent |
| References | Up to 6 Per Render | Varies |
| Hardware | Cloud (None Required) | Browser-based editor with web, image, video, 3D, and selected app export workflows |
| Install | None | Runs in a web browser; companion apps and platform exports support selected workflows |
| Cost | from $9/mo | Free access with optional paid plans |
Compare the workflows side by side and choose the one that fits the next task.
Skip a separate local scene build. Pick a condition, material, and background while RENDERCAD handles the image-generation step. Image renders complete in 60 seconds.

Get StartedCommon questions about RENDERCAD and this workflow
With RENDERCAD, upload or snip a clear image, describe carbon fiber, and add a material reference when exact visual direction matters. Image renders complete in 60 seconds.
Upload a clear view, describe the brushed-aluminum finish you want, and add a material reference when the visual direction matters. Because the result is generated from an image, inspect the grain direction and surface details against your original design before using it in a final presentation.
Describe an environment such as a sunny forest or urban street and use a reference image when needed. Image renders complete in 60 seconds without building a local scene file or environment map.
Start with a clear source view, choose a simple background, and describe the studio look you want. RENDERCAD can generate a presentation image without requiring you to build a traditional light rig, but the lighting is image-based and should be reviewed rather than treated as a physically measured setup.
RENDERCAD can generate orbit-style motion from a single image using a Camera option. Because the motion is inferred rather than rendered from a complete 3D model, review geometry and hidden-side details before publishing the result.
The Seamless Loop option is designed to improve continuity between the end and beginning of a generated video. Inspect the transition before publishing because generative motion and loop quality can vary by image and model.
RENDERCAD processes generation in the cloud, so it does not require a dedicated local rendering GPU. You still need a supported browser and internet connection, and normal browser, upload, and download activity can use local device resources.
RENDERCAD image renders complete in 60 seconds. Competing real-time tools may preview quickly, but final output speed still depends on scene complexity, hardware, export settings, and output quality.
RENDERCAD starts at $9/month with credits that refresh monthly - predictable costs with no upfront investment or perpetual license fees.
RENDERCAD starts from a supported 2D image such as a CAD viewport capture, product photo, or drawing. You do not need to import the native 3D scene, but you may need to capture or export a clear image from the source application first.
RENDERCAD can generate a visual interpretation of a described or referenced material without requiring shader parameters. It does not guarantee physically measured or specification-accurate material behavior, so validate critical color, grain, reflectivity, and finish details against approved references.
Yes. A clear viewport capture can become a more polished visual for a design review. Image renders complete in 60 seconds, making it practical to prepare or iterate presentation options.
