Artisanal Wood Yin-Yang Spinner
Live Preview
A sophisticated, high-fidelity loading component featuring a Yin-Yang symbol rendered with rich wooden textures. The design utilizes SVG turbulence filters to simulate realistic wood grain across contrasting 'Oak' and 'Walnut' finishes. The animation employs a smooth, eased rotation with a subtle 3D tilt effect, evoking a sense of balance and craftsmanship. Perfect for premium organic brands, carpentry portfolios, or zen-themed applications.

Frequently Asked Questions
How are the feTurbulence and feDisplacementMap primitives configured to achieve the distinct Oak vs. Walnut grain differentiation?
The component utilizes a single SVG filter definition where feTurbulence generates a Perlin noise base. To differentiate wood types, the CSS applies varying contrast and brightness filters to the pseudo-elements; the Oak side uses a higher frequency noise with a desaturated color matrix, while the Walnut side uses a lower frequency displacement scale to simulate broader, deeper grain patterns.
What CSS properties are utilized to ensure the 3D tilt effect remains hardware-accelerated during the continuous rotation?
To maintain 60fps performance, the component applies 'will-change: transform' and 'transform-style: preserve-3d' to the main container. The animation combines a 'rotateZ' for the spinner's cycle with a static 'rotateX(25deg)' perspective shift, ensuring the GPU handles the composite matrix calculations without triggering expensive layout repaints.
How is the Yin-Yang's complex S-curve geometry constructed using only CSS gradients and pseudo-elements?
The geometry is rendered by splitting a circular container with a 50/50 linear-gradient and then overlaying two pseudo-elements (::before and ::after). These pseudo-elements are sized at 50% of the parent's diameter, positioned on the vertical axis, and styled with matching background colors and internal radial-gradients to create the 'eye' of the wood grain, forming a seamless S-curve.
How does the implementation handle the scaling of Cinzel typography to prevent optical misalignment during high-speed rotations?
The Cinzel typeface is wrapped in a dedicated label container that uses 'backface-visibility: hidden' and absolute positioning relative to the SVG viewBox. By using 'em' units for letter-spacing and 'clamp()' for the font-size, the text maintains its artisanal legibility and centered anchor point regardless of the parent container's 3D transformation state.
Can the 'gnarliness' of the wood grain be dynamically adjusted for different wood species using CSS variables?
Yes, the SVG filter references CSS variables for the 'baseFrequency' and 'scale' attributes. By modifying the '--wood-grain-turbulence' variable, developers can transition the aesthetic from a fine-grained Mahogany to a highly knotted, rustic Pine look without modifying the underlying SVG markup or using JavaScript.
