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.
SimLab Composer is desktop 3D visualization software for importing CAD and 3D models, building scenes, creating rendered images, animation, 3D PDF, 360 views, and VR experiences.
SimLab Composer is strongest when a team has CAD or 3D model files and needs a prepared visualization scene with materials, cameras, animation, 3D PDF, 360 output, or VR interaction. RENDERCAD fits a lighter handoff: upload a CAD viewport, product image, architectural view, or design screenshot and generate a polished still render without managing import formats, scene hierarchy, desktop installation, or renderer settings. Use SimLab for model-based interactive deliverables; use RENDERCAD for faster still-image iteration from the view you already have.
SimLab Composer starts from model data. Users import CAD or 3D files, organize assemblies into scenes, adjust materials, set cameras and lighting, add options or animation, and then output renders, interactive 3D PDFs, 360 imagery, WebGL-style sharing, or VR experiences. That depth is useful for engineering communication, product visualization, training content, and architecture presentations where the deliverable needs to stay connected to a composed 3D scene. RENDERCAD starts from the visible design instead of the full scene graph. A designer can upload a viewport screenshot, exported product angle, interior view, facade study, or concept image and create a more presentation-ready still without converting the model, installing CAD plug-ins, rebuilding materials, or preparing an interactive experience. SimLab remains the better fit for animation, VR, simulation, 3D PDF, and reusable model-based assets. RENDERCAD is the better fit when the practical goal is quick client, sales, or review imagery from an existing visual.
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 SimLab Composer
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.
