MaxMath 1.1.1

English

MaxMath 1.1.1 improves 3D and contour plotting performance, gesture behavior, and coordinate readability.

Highlights

• Compiles parsed expressions once into positional-slot nodes for 3D and contour grid evaluation, avoiding repeated string parsing, map lookups, and temporary argument lists at every sample.
• Traverses contour cells once and prunes levels outside each cell's value range; matrix transforms now work in place and camera/projection work is cached.
• Re-samples contour meshes over the transformed data range after pan/zoom, preventing blank exposed areas.
• Keeps the 3D data range stable while increasing grid density as users zoom, so magnification reveals more detail without silently rescaling the axes.
• Adds data-bound bounding boxes, tick marks, and numeric labels to 3D and contour plots. Labels use a GL glyph atlas and are included in PNG exports.
• Fixes redraw cancellation leaving the loading indicator stuck, double-applied 3D zoom, incorrect near/far clipping, and precision loss in small 2D root labels.
• Adds extensive parity, tick, gesture, matrix, mesh, axes, glyph-layout, and full-rotation camera-framing tests.

These are structural performance improvements; this release does not claim unmeasured device benchmark numbers.

MaxMath 1.1.1 改进了 3D/等高线绘图性能、手势行为和坐标可读性。

主要改进

• 将解析后的表达式一次编译为定长变量槽位，用于 3D/等高线网格求值，避免每个采样点重复进行字符串解析、Map 查找和临时参数列表分配。
• 等高线改为按单元遍历并跳过超出值域的层级；矩阵变换原地执行，相机与投影计算进行缓存。
• 等高线平移/缩放结束后会按变换后的数据范围重新采样，避免拖出空白区域。
• 3D 放大时保持数据范围与坐标轴稳定，并提高网格密度，让放大真正展示更多细节。
• 3D 与等高线新增数据边界框、刻度线和数值标签；标签通过 GL 字形图集绘制，因此 PNG 导出也会保留坐标信息。
• 修复重绘任务取消后加载指示卡住、3D 双重缩放、近远裁剪错误及小数零点标签精度不足。
• 新增表达式一致性、刻度、手势、矩阵、网格、坐标轴、字形布局和全旋转相机取景测试。

这些属于结构性性能优化，本版本不宣称尚未实测的设备端性能数字。

MaxMath 1.1.0

English

MaxMath 1.1.0 refreshes the interface, adds complete dark-mode support, and makes long-running calculations easier to control.

Highlights

• Added complete Material 3 light and dark themes with unified colors, typography, shapes, spacing, and sizing.
• Applied theme-aware palettes to live 2D, 3D, and contour plots; dark-mode cold starts no longer flash a white window.
• Added a visible cancel action to every calculation page. Recalculation keeps the previous result visible, cancellation restores it, and completed results scroll into view.
• Redesigned loading and error cards with engine warm-up guidance, expandable and copyable error details, and monospaced Maxima output.
• Disabled unwanted autocorrection/capitalization for math input, enabled symbolic limit/integration bounds, and preserved matrix, vector, and quadratic-form cells across screen rotation.
• Added directional navigation transitions, improved accessibility labels, and kept exported plot PNG files on a share-friendly light background.
• Added regression coverage for cancellation, state recovery, matrix saving, plot palettes, and WCAG AA color contrast.

MaxMath 1.1.0 全面刷新界面、补齐深色模式，并让长时间计算更容易控制。

主要改进

• 建立完整的 Material 3 浅色/深色主题，统一配色、字体、圆角、间距和尺寸。
• 实时 2D、3D 与等高线绘图同步适配主题；深色模式冷启动不再白闪。
• 所有计算页面加入可见的取消入口；重算保留上一结果，取消后恢复结果，完成后自动滚动到结果区。
• 重新设计加载与错误卡片，增加引擎预热提示、可展开/复制的错误详情和等宽 Maxima 输出。
• 关闭数学输入中的自动纠错与自动大写，支持符号形式的极限/积分边界，并让矩阵、向量与二次型单元格在屏幕旋转后恢复。
• 加入方向性导航动画、改进无障碍标签，同时让导出的绘图 PNG 保持适合分享的浅色背景。
• 新增计算取消、状态恢复、矩阵保存、绘图配色及 WCAG AA 色彩对比度回归测试。

MaxMath 1.0.1

English

MaxMath 1.0.1 is a performance and package-size optimization release.

Highlights

• Removed 38.3 MB of duplicate and documentation-only engine assets, and made runtime upgrades rebuild the extracted engine directory cleanly.
• Reuses a warm Maxima subprocess between clean requests, with state reset, timeout/cancellation recovery, and a 60-second idle lifetime.
• Reduced allocation and boxing in the 2D/3D plotting hot paths by reusing buffers, paths, paints, meshes, and renderer state.
• Combined plot probes into fewer engine round trips and moved bitmap decoding to the IO dispatcher.
• Enabled Gradle build caching/parallelism and expanded CI with unit tests, assembleDebug, and Android lint.

See the optimization notes for implementation details.
