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.
Ansys Speos is optical and lighting simulation software for modeling light propagation, illumination, optical properties, sensor vision, and human-vision results from CAD-based product designs. It serves optical, automotive, display, and product engineering teams that need validation-oriented results.
Ansys Speos is strongest when a team needs physics-based optical validation: CAD geometry, light sources, optical properties, sensors, photometric analysis, and human-vision review. RENDERCAD is a better fit for fast presentation imagery from a viewport, product render, or concept screenshot when the output does not need engineering-grade optical measurements. Treat RENDERCAD as a visual companion for reviews and marketing drafts, not a replacement for Speos simulation.
Speos requires optical scene construction: CAD or imported geometry, light sources, measured surface and material properties, sensors, simulation controls, and analysis setup. It can support headlamp, HUD, display, interior lighting, camera, and lidar workflows where luminance, illuminance, intensity, optical behavior, and human-vision review matter. RENDERCAD does not solve those measurement or validation tasks. It is useful when a designer, marketer, or engineering stakeholder already has a Speos view, CAD viewport, product concept, or lighting study image and wants a polished visual quickly without rebuilding a ray-traced optical scene. Choose Speos for validated light behavior and sensor work; choose RENDERCAD for non-measurement image polish, review visuals, proposals, and early concept communication.
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 Ansys Speos
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.
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.
