RNDRSParametric options, photoreal at once
Your definition generates fifty options; your renderer makes you choose one to visualize. RNDRS breaks that bottleneck — capture viewport frames of your Grasshopper iterations and render the whole option space photorealistically, with a consistent prompt for honest comparison.
Drag to compare — one upload, one wire, eleven seconds
From Grasshopper to photoreal
Viewport captures of baked or previewed iterations
Drop multiple captures onto one RNDRS canvas

Node canvas meets node thinking
RNDRS is itself node-based — wire captures to render nodes, branch variations, and keep the whole study reproducible. It maps naturally onto how you already work in Grasshopper.
Consistent style across options
Reusing the same prompt across iterations isolates the geometry as the only variable — the fairest way to evaluate (and present) a parametric study.
From study to showpiece
When an option wins, upscale it to 4K, extend the frame for the board and animate a camera move — without ever opening a traditional render engine.
Frequently asked questions
How do I get Grasshopper geometry into RNDRS?
Capture the Rhino viewport (ViewCaptureToFile) with your previewed or baked geometry visible, then upload the images. No baking to final materials required.
Can I render many iterations efficiently?
Yes — upload multiple captures to one canvas and wire them to render nodes sharing the same prompt. Each render takes ~11 seconds.
Does complex parametric geometry confuse the AI?
Patterned facades, lattices and doubly-curved surfaces render well from clear captures. Arctic or shaded view modes with good contrast give the most faithful reads.
Is there an API for automated rendering?
Batch and API workflows are on the roadmap. Today the canvas-based flow is the fastest way to render option matrices — most studies of 10–20 options take a few minutes end to end.
