DLA Form Generation dataset

This dataset consists of 2,500 3D forms created using a Differential Line Algorithm (DLA) based method. Multiple closed 2D line segments develop over time. At each time-step the geometry is captured and forms a sequential z-layer in a 3D form. After several hundred time-steps, the final 3D form is generated, suitable for 3D printing. Each image is 600x600 pixels resolution. Images in this set are 3D line renderings of the final form, from a perspective projection and orthographic projection in the x-y plane.There are 9 separate runs with associated csv files. The associated images are in the imgs.zip file

本数据集包含2500个基于差分线算法（Differential Line Algorithm，DLA）方法生成的三维形体。多个闭合二维线段随时间推移不断演化：每一个时间步都会捕捉当前几何形态，并将其作为三维形体的连续z轴层。经过数百个时间步后，最终生成适用于3D打印的完整三维形体。所有图像分辨率均为600×600像素，均为最终三维形体的三维线框渲染图，分别采用透视投影与x-y平面正交投影两种方式生成。本数据集包含9组独立运行结果，每组均配有对应的csv文件，配套图像文件均存放于imgs.zip压缩包内。
