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.
Patchwork 3D is Lumiscaphe desktop software for turning CAD models into photorealistic product images, videos, and interactive presentations. It focuses on digital aspect mockups, material libraries, product variants, lighting, environments, and CAD import workflows for design review and marketing.
Patchwork 3D is strongest when a team has prepared CAD data and wants a controllable desktop product-visualization pipeline with variants, materials, HDRI environments, and interactive review. RENDERCAD is better when the input is already visible in a CAD viewport, configurator, sketch, or presentation image and the goal is to turn that capture into a polished render without importing geometry, rebuilding materials, or managing workstation rendering setup.
Patchwork 3D works from 3D product data, so the workflow starts with CAD import, scene preparation, material assignment, lighting, and variant management before outputting images, videos, or interactive presentations. That gives design and marketing teams detailed control over product configurations and digital aspect mockups, but it also assumes access to model files, Windows desktop software, compatible graphics hardware, and a user who can maintain the visualization scene. RENDERCAD approaches the same visual communication problem from the opposite direction: upload a design capture or viewport image and use cloud AI rendering to improve the image without a CAD export or local render setup. Patchwork 3D remains the deeper option for teams that need reusable 3D assets and precise variant libraries; RENDERCAD is the faster fit for concept reviews, sales visuals, architectural views, and product images when the visual input is already on screen.
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 Patchwork 3D
Yes. The Seamless Loop option ensures the last frame matches the first for perfect looping - ready for social media, websites, and displays.
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.
RENDERCAD still-image jobs usually complete in about 10 - 60 seconds. Competing renderer speed depends on scene complexity, render settings, hardware, queue time, and final output quality.
Yes. RENDERCAD runs independently as a browser app or overlay, so you continue modeling while renders process in the background.
RENDERCAD works from 2D images. Upload a CAD screenshot, real photo, or hand drawing - no file conversion, no exports, no compatibility issues.
Minimal. RENDERCAD uses natural language prompts anyone can use immediately - no technical sliders, shader graphs, or render settings to learn.
RENDERCAD excels at rapid client presentations. It delivers impressive photorealistic results in seconds, enabling real-time feedback sessions during design reviews.
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. Select the Realistic engine, set Condition to Clean, and type "Brushed Aluminum." The AI applies correct texture orientation to your geometry automatically.
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.
RENDERCAD handles studio lighting automatically - select a Gradient or White background for a clean studio look. No manual light placement or HDRI setup needed.
Yes. Add "Golden Hour" to your prompt and the AI handles warm color temperature, long shadows, and soft light automatically.
