How photorealistic jewellery rendering works
A photorealistic render turns a CAD model into an image that looks like a photograph. The software simulates how light behaves, so the result looks real.
1. The model
The render shows only what is in the model. Every prong, bead and engraving must be built into the CAD. See the checklist for details that matter.
2. Materials
Metals are given a material that reflects light like gold, platinum or silver. Gems are given materials that bend and split light, so diamonds show brilliance and fire. A diamond's refractive index is about 2.4, which is much higher than glass.
3. Lighting
The scene is lit with soft boxes or a special environment image. The lighting decides where reflections fall, and a good setup makes metal look rich and stones look bright.
4. Camera and angle
Camera position, lens and depth of field are set like a photographer's, to show the piece from the best angle.
5. Rendering and editing
The software calculates the image, which can take minutes. The result is then lightly corrected, resized and saved. Our KeyShot renders are delivered at 2000 px. See how KeyShot and AI renders differ.
Frequently asked questions
Why do renders take time?
The software traces how light moves around metal and stones, which takes calculation, especially for diamonds.
Can a render show something that cannot be made?
Yes, if the model has errors. That is why the model should be checked for casting as well as for looks.
