IsoAlgo3d - A PCF 3D Viewer for Desktop, Tablet and Smart phone

     摘要: Abstract. IsoAlgo3d 通过将PCF三维可视化，并导出HTML文件。由于使用WebGL技术，所以只要设备支持HTML5，就可以不用安装任何软件或插件直接浏览PCF对应的全尺寸标注的管道三维模型，不管是电脑、平板还是智能手机。三维直接浏览管道模型，更加直观，避免了二维ISO图有时表达不清晰的情况，如环管出图，复杂管线分图后识图困难等，方便现场施工。

FreeType in OpenCASCADE

     摘要: Abstract. FreeType is required for text display in the 3D viewer. FreeType is a software font engine that is designed to be small, efficient, highly customizable, and portable while capable of producing high-quality output(glyph images). It can be used in graphics libraries, display servers, font conversion tools, text image generation tools, and many other products as well. The blog is focus on the FreeType usage in OpenCASCADE to convert text to BRep shape.

三维电梯仿真软件开发3D

     摘要: 本系统的电梯模型模拟三层楼，当轿厢系统上升（下降），重量平衡系统下降（上升），顶部的曳引系统则类似一个轮轴，要不停的旋转顺时针（逆时针），当电梯到达指定楼层时，轿厢的门能开关。因此现阶段的动画要求是实现轿厢系统上下运动、重量平衡系统上下运动、曳引机的旋转和轿厢门的开关动画。  阅读全文
