OpenCASCADE中散亂Edge生成Wire

摘要: 在OpenCASCADE中生成WIRE時(shí)要求添加到WIRE中的邊EDGE是有順序要求的。當(dāng)給定的邊沒(méi)有按順序添加到WIRE之前，需要自己將EDGE按順序處理。OpenCASCADE中也提供了對(duì)EDGE按順序進(jìn)行排序的功能，方便WIRE的生成。
　　本文給出將散亂的EDGE排序后生成WIRE的實(shí)現(xiàn)代碼，這個(gè)功能用處還是很大的。閱讀全文

Boolean operations between triangle meshes

摘要: OpenCASCADE提供了基于BREP體的Boolean Operations，但是如果Topo體中只包含三角網(wǎng)格信息的話，是不支持布爾運(yùn)算的。典型的例子就是由STL導(dǎo)入生成的模型在OpenCASCADE中是不能進(jìn)行布爾運(yùn)算。

有一些開(kāi)源庫(kù)提供了基于三角網(wǎng)格的布爾運(yùn)算的功能。如MeshLab、Cork等。本文主要就來(lái)介紹一下這兩個(gè)庫(kù)中的基于三角網(wǎng)格的布爾運(yùn)算功能。閱讀全文

[轉(zhuǎn)]Massive Model Rendering Techniques

摘要: We present an overview of current real-time massive model visualization technology, with the goal of providing readers with a high level understanding of the domain, as well as with pointers to the literature.

本文展示了當(dāng)前大規(guī)模模型實(shí)時(shí)可視化技術(shù)的概況，目的是為了給讀者們對(duì)這個(gè)領(lǐng)域一個(gè)比較深入的認(rèn)識(shí)，并指出學(xué)術(shù)界的一些研究的文獻(xiàn)。閱讀全文

OpenCASCADE Texture Mapping

摘要: Abstract. 紋理貼圖技術(shù)的出現(xiàn)和流行是圖形顯示技術(shù)的一個(gè)非常重要的里程碑，直接影響3D技術(shù)從工業(yè)進(jìn)入娛樂(lè)領(lǐng)域。本文結(jié)合OpenCASCADE中紋理貼圖的源碼，來(lái)說(shuō)明紋理貼圖在OpenCASCADE中實(shí)現(xiàn)。
