Three.js is an open-source JavaScript 3D library for creating browser-based 3D scenes. Developers assemble a scene graph, camera, lights, geometry, materials, interaction, and animation, then render to a canvas with WebGL or WebGPU-capable tooling. It is well suited to interactive product viewers, configurators, data visualizations, games, and custom web experiences where the team owns the runtime and its behavior. Three.js commonly works with prepared glTF or GLB assets, textures, and application code rather than serving as a CAD authoring environment.
Three.js is the right tool when the result must remain an interactive browser experience: a product viewer, configuration interface, explorable scene, or animated canvas built in JavaScript. RENDERCAD addresses a different moment in that workflow. Start with a deliberate Three.js viewport capture showing the chosen camera angle, silhouette, proportions, and key product details, then use RENDERCAD to explore a more polished static presentation for a concept review, sales deck, landing page, or campaign. This can be useful when a team needs credible visual directions without building a separate lighting, shader, post-processing, and image-export pipeline for every still. The Three.js scene remains the source of truth for geometry, interaction, and live behavior; RENDERCAD is for presentation imagery rather than a replacement for the web runtime.
Three.js gives developers direct control of a browser scene: objects, cameras, lights, rendering, animation, controls, asset loading, and custom material behavior can all be defined in code. Its glTF loader supports bringing prepared glTF assets into an application, while the renderer and capture setup remain part of the team's implementation. That control is valuable for an interactive viewer, product configurator, or embedded 3D feature, but it also means the team is responsible for optimizing models and textures, selecting camera and lighting behavior, handling browser and device constraints, and producing any high-resolution captures required by the project.
A practical RENDERCAD workflow begins after the important design decisions are visible in a Three.js frame. Capture a clean, well-composed viewport image of the product or architectural scene, with the intended angle and details readable. Use that image to develop polished render directions for stakeholder review, concept exploration, marketing mockups, or a static hero visual. Compare results against the original capture so that product form, proportions, interfaces, and brand-specific details remain grounded in the source. For current implementation guidance on connecting an application workflow, use RENDERCAD developer documentation.
RENDERCAD does not create the interactive scene graph, animation system, controls, or production browser integration that Three.js provides. It also should not be treated as the authoritative record for exact geometry or product configuration. Use Three.js when users need to explore and manipulate the model in the browser; use RENDERCAD when the priority is a strong still image derived from an established view.
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.

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.

Get StartedCommon questions about RENDERCAD and this workflow
RENDERCAD avoids much of the scene, shader, and local-renderer setup used by traditional rendering tools. Users still need to prepare a useful source image, choose suitable options, describe the intended result, and review generated details.
RENDERCAD starts at $9/month with credits that refresh monthly - predictable costs with no upfront investment or perpetual license fees.
RENDERCAD is designed to create more polished, realistic-looking presentation images from a source view. Results vary by input and settings, and generated images should be checked against the original model before they are used to communicate exact design details.
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.
Describe the wood species and finish you want, and provide a reference image when scale or grain direction matters. RENDERCAD can generate a wood-like visual treatment, but it does not replace model-level texture mapping or guarantee an exact, repeatable grain pattern.
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.
Yes. Request a golden-hour look and describe the mood or direction you want. The generated warmth, shadows, and light direction can vary between results, so compare important design details with the source image.
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.
RENDERCAD's Create Video workflow generates a video from a single image and provides Camera and Product Motion controls. Videos complete in 2-5 minutes.
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.
Usually. Generation runs in the cloud, so it does not occupy a local renderer. Keep the relevant browser workflow available as required, and expect normal network and browser resource use while the job is submitted and results are loaded.
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.
