60 SECONDS. ZERO CONFIGURATION. STUNNING RESULTS.
Sunflow is an open-source Java rendering system for photo-realistic image synthesis, built around a ray tracing core and global illumination scene setup.
Sunflow is a hands-on Java renderer for users who want to describe full 3D scenes, shaders, lights, cameras, and sampling settings before producing an offline image. RENDERCAD is built for a different moment in the workflow: upload a CAD, product, or architectural viewport screenshot and get a polished AI render without exporting geometry, writing scene files, or tuning a local ray tracer. Sunflow is useful for renderer experiments and custom scene control; RENDERCAD is more practical when the design view already exists and the goal is a fast presentation visual.
Sunflow and RENDERCAD both serve visual output, but they start from very different inputs. Sunflow expects a complete render scene: geometry, camera, lights, shaders, global illumination settings, Java runtime setup, and enough local compute to finish the job. That can be valuable for developers or technically comfortable artists who want to study or customize a ray tracing pipeline. RENDERCAD starts from the viewport image you already have, so designers can improve CAD screenshots, product angles, architectural views, and marketing visuals without rebuilding the model inside a separate rendering system. Use Sunflow when open-source scene control is the priority; use RENDERCAD when the priority is turning an existing design view into a clean render quickly. For automated RENDERCAD workflows, start at /developers instead of maintaining a custom renderer integration.
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 Sunflow
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.
