The T-Shirt Fabric Wrinkle Mockup Generator renders realistic apparel mockups by warping uploaded graphics across dimensional cloth folds and shadow contours directly on an HTML5 canvas.

### Rendering Architecture & Blend Techniques The tool composites custom artwork onto garment textures using standard 2D canvas blend operations: - **Base Garment Palettes**: Select from core apparel color presets including Black (#18181B), White (#F4F4F5), Navy (#0F172A), and Sand (#D4C4B5). - **Cloth Fold Gradient Modeling**: Generates multi-stop linear gradient shading simulating directional studio lighting across undulating fabric creases. - **Dynamic Composite Blending**: Automatically toggles global composite modes based on substrate luminance—applying "screen" blending for dark fabrics (Black/Navy) and "multiply" blending for light garments (White/Sand). - **Adjustable Wrinkle Depth**: Fine-tunes secondary shadow overlay density ("rgba(0,0,0,depth / 250)") from subtle ripples to heavy cotton folds. - **Instant Export**: Downloads the completed 600×600 composite preview as a high-resolution PNG ("tshirt-wrinkle-mockup.png").

### Practical Usage Example Testing a vectorized brand emblem on a heavyweight black cotton t-shirt: 1. Upload a transparent PNG logo file into the graphic uploader. 2. Select the **Black** garment swatch; the canvas applies screen blending to preserve design highlights. 3. Adjust the **Wrinkle Depth** slider to 65 to blend realistic fabric shadow ripples through the graphic. 4. Click **Download PNG Mockup** to export the finished product presentation image.

### Honest Processing & Privacy Note All image uploads, canvas composite operations, and PNG exports execute locally inside your browser memory. No apparel designs, logos, or brand graphics are uploaded to any external server.
