How to Use the 3D Shape Generator
- Pick a shape from the shape grid: ring, sphere, ribbon knot, cone, capsule, or blob.
- Drag on the preview to rotate it and see how the lighting falls from different angles.
- Adjust the key light and fill light colors, glow intensity, and rim softness until it matches your site’s look.
- Set the background color, or leave transparent background checked if you want to drop it straight onto your own site background.
- Export as PNG, JPEG, or record it as a rotating WebM video.

Customize Lighting and Glow
Key Light and Fill Light Colors
The generator uses two lights, a key light and a fill light, each with its own color. The key light does most of the work defining the shape’s main highlight, while the fill light adds a second color into the shadows and edges. Setting these to two contrasting brand colors is what gives the shape its gradient-like glow rather than a flat single-color render.
Light Angle and Glow Intensity
Light angle rotates both lights around the shape together, so you can quickly find the angle that best shows off the form without moving the shape itself. Glow intensity controls how strong the lighting effect reads overall, lower values give a subtle, muted look, higher values give a bright, glowing look that stands out more against dark backgrounds.
Highlight Sharpness and Rim Softness
Highlight sharpness controls how tight or spread out the bright specular highlight is on the surface, sharper values look more like polished metal or glass, softer values look more like matte plastic. Rim softness controls the glowing edge effect around the outline of the shape, a harder rim gives a defined, almost neon-outline look, while a softer rim blends the edge more gradually into the background.
Export Your 3D Shape
Download as PNG or JPEG (Transparent Background)
PNG export keeps the background fully transparent by default, so you can place the shape directly on your existing website background color without a visible box around it. JPEG export fills in your chosen background color instead, useful if you need a flat image for somewhere transparency isn’t supported.
Record as Video (WebM)
You can record the shape rotating and download it as a WebM video, with a choice of duration (2 to 20 seconds) and quality (standard or high). This is useful for hero section background videos or subtle looping animations, without needing any video editing software.
Why Use This 3D Shape Generator
- Completely free, no account or signup required
- No watermark on any exported PNG, JPEG, or video
- Runs entirely in your browser using WebGL, nothing to install
- Transparent export means the shape blends into your site’s actual background color instead of sitting in a visible box
- Animated video export lets you use a rotating shape as a background element, not just a static image
- Full control over lighting and glow instead of fixed presets
Pair it with the CSS Gradient Generator to match your background gradient to the shape’s glow colors, or use the Grid Calculator to lay out your hero section around it.
