五种3D表示方法总览

Layout

Five vertical cards arranged in a single row, each card representing one 3D representation method. A thin decorative line connects them at the bottom. Title “3D表示方法” at top center in large handwritten font.

ZONES

Title Zone: Top center, large text “3D表示方法” with a small 3D cube icon
Card 1 - Mesh: Leftmost card, showing a triangulated surface
Card 2 - Voxel: Second card, showing a 3D grid of small cubes
Card 3 - Point Cloud: Center card, showing scattered dots on a surface
Card 4 - SDF: Fourth card, showing concentric contour shells with a zero-level set highlighted
Card 5 - NeRF: Rightmost card, showing a 5D coordinate function with rays
Bottom Zone: Thin connecting line with small arrows showing implicit relationships

LABELS

Each card contains:

Mesh: “Mesh 三角网格”, formula “M = (V, E, F)”, keyword “流形 / 水密”, small icon of triangulated sphere, tag “GPU硬件加速”
Voxel: “Voxel 体素”, formula “f: Z³→R”, keyword “O(N³)显存”, small icon of cube grid, tag “256³≈16M单元”
PointCloud: “点云 Point Cloud”, formula “P = {pᵢ}⊂R³”, keyword “置换不变”, small icon of scattered points, tag “k-NN / Ball Query”
SDF: “SDF 符号距离场”, formula “f(x)<0 内 / f(x)=0 面 / f(x)>0 外”, keyword “Eikonal: ‖∇f‖=1”, small icon of contour lines, tag “布尔运算: min/max”
NeRF: “NeRF 神经辐射场”, formula “F: (x,y,z,θ,φ)→(r,g,b,σ)”, keyword “视角相关颜色”, small icon of camera rays, tag “体密度σ / 透射率T”

STYLE

Flat vector illustration. Clean black outlines on all elements. Each card is a rounded rectangle with a colored header strip and white body. Geometric simplified icons inside each card (no gradients). Playful decorative dots and small geometric shapes scattered in background. Keywords in bold handwritten-style font. Formulas in clean sans-serif.

ASPECT

16:9 landscape

Clean composition with generous white space. Simple or no background. Main elements centered or positioned by content needs. Color values (#hex) and color names are rendering guidance only — do NOT display color names, hex codes, or palette labels as visible text in the image. Text should be large and prominent with handwritten-style fonts. Keep minimal, focus on keywords. Language: Chinese.
