3D boards, analysis tools, and help
Five 3D themes, soft under-board lighting, analysis tools, and a searchable help center with plain-language guides.
Added
- A 3D board inside the main egui game workspace, with a fixed perspective, zoom, textured pieces, a marble board, lighting, and soft contact shadows.
- A View menu choice and a 2D/3D button beside Flip Board for switching board modes.
- A single 3D appearance control for brightness, contrast, and gloss, defaulting to 85.
- Coordinates, move highlights, and best-move arrows on the 3D board.
- Captured-piece icons and material-advantage information beneath each player’s name, updated for the selected position during game review.
- Graphical piece choices in the promotion window.
- Marble, Wood, Glass, Art Deco, and Egyptian 3D themes in View > Board > 3D theme.
- A soft radial glow beneath the 3D board, with cool blue light for Marble and Glass and warm amber light for Wood, Art Deco, and Egyptian. The glow follows the board when rotating or zooming.
- A position preview beside the analysis details below the full-width expanded graph. It follows the selected or hovered position and marks the last move.
- An Elo calculator under Tools with rating controls, expected score, win/draw/loss projections, and an adjustable K-factor. Chess.com and Lichess modes are labeled as estimates.
- A searchable, topic-filtered Help center accessible from Help > Contents in the game and from the public website. Its Markdown articles have direct URLs that search engines can index, and new articles can be published without rebuilding the game WASM.
- Twenty plain-language help guides covering analysis scores, CPL, accuracy, move symbols, engine lines, FEN, PGN, Elo, the Position Editor, and importing puzzle positions from another site using a FEN or screenshot.
Improved
- The board grows with the available workspace, with the 3D view positioned to use more of the screen.
- 3D rendering, move navigation, and zoom responsiveness have been refined.
- Random facing directions now apply to every 3D piece type. Returning to the same position restores the same orientations.
- Copy Board to Clipboard in Game Moves now creates a board image from the active 2D or 3D view.
- Added desktop and WebGPU compatibility guidance to the Features page.
- Refined piece placement, square highlights, perspective, lighting, materials, antialiasing, and coordinate placement across the 3D themes.
- Desaturated the Wood theme’s board to a near-neutral gray while retaining its grain and square contrast, and darkened its black pieces to distinguish them from the white pieces.
- Left-aligned and widened the Help contents sidebar for easier scanning.
- Expanded the gold menu border treatment across the application.
Removed
- Removed the Sci-fi and Bauhaus 3D piece sets. Saved selections of either theme now fall back to Marble.
