HW#15 Fractals (選做題，可不做)

1. Generate fractals from text. You may choose two themes to present. The following are some examples and the prompts that generate them.

artifact (share)

3d fractal cloud plain cloud

Clouds & lightning

artifact (share)

artifact(share)

artifact, fly thru woods

Trees are fractals

2. identify hazards in a fractal 3d assessment display, first person perspective, according to a real world photo, more in photo gallery Choose any photo to proceed with.

依據照片重建三維碎形場景，辨識其中可能的危險部位，需考慮視角與觀測位置轉換以便可以瀏覽各處細節，提供影像庫選取一張照片(可使用自選)

樣本參考

share, artifact

樣本參考

1. add 3d model in three.js

2. fractal 3d trees

3. a node's label only resolves once the probe reaches it

4. faithful positioning (like the photo)

3. Visualize fractals

Make 2 fractals resembling natural 3d object such as clouds, lungs, blood vessels, ocean waves, and forests.

HW#14 Robot and BLV Navigation

課堂練習

Deadline: Saturday at 23:59 (one more week)

Send all the share links to me chang212@gmail.com by email with subject HW#14 [your id, your name]

3 選一

1. 參考Voronoi navigation app，製作以下場景的導航

task 1: make an entrance/exit. make the auto-navigation route deliberately exit through this gate (e.g., a waypoint placed just outside on the brick path) and go to central woods as destination.

task 2: set FPV (first-person view) and maintain horizontal view angle

task 3: show Voronoi Waypoints for navigation

提示：給還不熟悉Claude 的同學，如何套用既有導航系統到這個溜冰場情境(如照片)，已經會套用artifact 同學可以跳過

2. Implement Voronoi-based navigation for robots or BLV users

Non-Voronoi Navigation

3. Benchmark the two static vs. dynamic Voronoi-based navigation. 30 seeds.

以下是比較不同演算法得出的繞線以及比較不同繞線的電路效能

Problem 2

suggestions

- Add a short note on how CL1 and CL2 set the load capacitance the crystal sees: CL = (CL1*CL2)/(CL1+CL2) + Cstray. With 22 pF caps this lands near the common 12 to 18 pF crystal spec once stray is included, and stating it explicitly ties your part choices to the datasheet.

1. Optimize trace routing for the Differential Pair Circuit on PCB

trace routing, share (artifact, more accurate schematic)

Steps

Starting from the imperfect design, complete the trace routing. Do trace routing ( 參考 share, share 2, share 3)

我是希望你們可以自行變換

無論是優化，更換演算法，UI 都可以，總之不是複製

2. 設計Crystal 石英振盪電路的PCB

除了ＰＣＢ視覺化，我是希望可以做一下 sensitivity analysis 或是 heat map

(3, 4 任選一題來做)

3. 使用鑽孔路徑演算法進行以下PCB 鑽孔(演算法提供參考)

甚麼是 TSP?

Traveling Salesman Problem 簡稱TSP

(一個推銷員要拜訪所有客戶城市，每個城市只能拜訪一次，最後要回到出發城市，請為他/她計算最短的拜訪路徑)

TSP在工業界有重要應用，包括物流（UPS/Amazon配送路線優化）、製造業（電路板鑽孔、機器人組裝路徑）、電信（網路路由、線路安裝）和能源（電網維護、管線檢查）。凡是需要造訪多個地點同時最小化成本、時間或距離的場合都適用。現代變體能處理容量限制、時間窗口等實際約束。企業使用OR-Tools、Gurobi等專業軟體解決這些問題，透過優化倉儲揀貨、切割模式、3D列印路徑和車隊管理等作業，往往能節省數百萬成本。
