基于给定的双方程系统，构建4维超高端凸纤维的数学模型：
$$\left\{ \begin{array}{r}
{r(\theta,\varphi)}_{超高端凸纤维}^{4维} = - ArcSin\left\lbrack \frac{1}{{BGM}_{{(\theta,\varphi)}_{Matrix}^{}}^{探针模型} \pm {MCM}_{{(\theta,\varphi)}_{Matrix}^{}}^{记忆悬浮}} \right\rbrack \times ArcCos\left\lbrack \frac{1}{{BGM}_{{(\theta,\varphi)}_{Matrix}^{}}^{探针模型} \pm {MCM}_{{(\theta,\varphi)}_{Matrix}^{}}^{记忆悬浮}} \right\rbrack + 2\pi N_{1}^{} + \frac{3\pi}{4} \\
\\
{r(\theta,\varphi)}_{超高端凸纤维}^{4维} = + ArcSin\left\lbrack \frac{1}{{BGM}_{{(\theta,\varphi)}_{Matrix}^{}}^{探针模型} \pm {MCM}_{{(\theta,\varphi)}_{Matrix}^{}}^{记忆悬浮}} \right\rbrack \times ArcCos\left\lbrack \frac{1}{{BGM}_{{(\theta,\varphi)}_{Matrix}^{}}^{探针模型} \pm {MCM}_{{(\theta,\varphi)}_{Matrix}^{}}^{记忆悬浮}} \right\rbrack + 2\pi N_{2}^{} - \frac{5\pi}{4}
\end{array} \right.$$
其中：
- BGM(θ,φ)Matrix：探针模型在球坐标下的矩阵表示
- MCM(θ,φ)Matrix：记忆悬浮约束矩阵
- N₁, N₂：相位整数参数，控制周期性结构
- ± 操作：表示模型的两种可能状态（叠加/干涉）
新增功能：
- 多种数学函数：提供五种不同的数学函数可视化
- 线框模式：可切换实体和线框显示模式
- 网格显示：控制参考网格的显示
- 模型导出：可将当前模型导出为OBJ格式
