  2. WYSIWYG NPR Overview Interface Descriptions Rendering System & Shaders Stroke Styles & Features Hatching & LOD Methods Summary & Conclusions Points for Discussion Table of Contents

  3. What is WYSIWYG NPR? How does it work? Who should use it? What purpose does it serve? WYSIWYG NPR Overview

  4. Tablet, mouse, or keyboard used for input Three editing modes: Line editing mode Hatching editing mode Basecoat editing mode Interface Descriptions

  5. Line Editing Mode

  6. Hatching Editing Mode

  7. Basecoat Editing Mode

  8. Triangle mesh used for models Mesh divided into patches Each patch rendered by four shaders: Background and base coat shader Stroke formation shader Stroke visibility shader Media simulation shader Rendering System & Shaders

  9. Rendering System & Shaders

  10. Four types of strokes: Decal strokes Crease strokes Silhouette strokes Hatching strokes Stroke Styles & Features

  11. Stroke Styles & Features

  12. Two types of hatching: Fixed hatching Mobile hatching Two types of LOD control: Structured hatching Free hatching Hatching & LOD Methods
