Create stunning photorealistic images and videos from any CAD system, real life photo, or even a quick napkin sketch.
60 SECONDS. ZERO CONFIGURATION. STUNNING RESULTS.
Three.js is an open-source JavaScript 3D library for building browser-based scenes with WebGL and WebGPU renderers, cameras, lights, materials, loaders, animation, and interaction. It fits product viewers, configurators, games, data visualization, and custom web experiences where developers control the runtime.
Three.js is best when the deliverable is an interactive 3D canvas, configurator, game, or product viewer built in JavaScript. RENDERCAD is better when you already have a CAD viewport, product image, or Three.js screenshot and need a polished static render for review or marketing without building lights, shaders, export code, or a web app.
Three.js gives developers direct control over scenes, cameras, geometry, WebGL or WebGPU rendering, glTF assets, materials, animation loops, controls, and custom shaders. That control is valuable for browser-based 3D experiences, but the visual result depends on prepared models, material work, lighting, performance budgets, browser support, and capture or export code. RENDERCAD does not replace a Three.js runtime for interactive viewers. It is a simpler follow-on or alternative when the goal is a high-quality still image: upload a CAD or web viewport screenshot, product concept, or model view and generate a photorealistic interpretation in the cloud. Use Three.js for interactive web 3D; use RENDERCAD for fast presentation stills, landing page imagery, concept refinement, and visual exploration when a full coded scene pipeline is unnecessary.
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.

Get StartedCommon questions about RENDERCAD vs Three.js
Minimal. RENDERCAD uses natural language prompts anyone can use immediately - no technical sliders, shader graphs, or render settings to learn.
RENDERCAD starts at $20/month with credits that refresh monthly - predictable costs with no upfront investment or perpetual license fees.
For product marketing, client presentations, and concept work - yes. The Realistic engine is designed to improve lighting, materials, and presentation quality while keeping the original design recognizable.
Yes. RENDERCAD understands materials semantically - it knows what brushed aluminum should look like without you defining roughness values, IOR, or shader parameters.
RENDERCAD generates unique, non-repeating grain patterns that follow your object's form. Prompt "Oak Wood" and the engine handles scale, direction, and variation automatically.
With RENDERCAD, upload your image or snip your screen, type "Carbon Fiber" in the prompt, and the AI retextures your image realistically in 10-60 seconds. No UV mapping or texture coordinates required.
Yes. Add "Golden Hour" to your prompt and the AI handles warm color temperature, long shadows, and soft light automatically.
Prompt "Sunny Forest" or "Urban Street" and RENDERCAD generates a matching environment in 10-60 seconds. No scene file or environment map setup.
RENDERCAD creates videos from a single image in 1-2 minutes using AI. Upload a CAD screenshot, real photo, or hand drawing, select Image to Video, and choose a camera movement - no animation timeline required.
Yes. The Gentle Orbit camera setting generates subtle rotation from a single static image automatically.
Yes. RENDERCAD runs independently as a browser app or overlay, so you continue modeling while renders process in the background.
No. RENDERCAD runs on cloud GPUs, so you can render 4K images on a basic laptop or even a Chromebook. Your computer never slows down.
