四.獲取SolidWorks中的材質(zhì)信息
SolidWorks插件-將SolidWorks文件轉(zhuǎn)換為gltf格式
- 一.SolidWorks文件轉(zhuǎn)換為glTF格式
- 二.搭建一個Taskpane的SolidWorks插件
- 三.獲取SolidWorks文件中的網(wǎng)格信息
- 四.獲取SolidWorks中的材質(zhì)信息
- 五.轉(zhuǎn)換為glTF格式
- 六.裝配體和多實體格式的轉(zhuǎn)換
- 去Github查看代碼或下載插件安裝包
4.1 關(guān)于材質(zhì)
其實在上一節(jié)的代碼里已經(jīng)有獲取SolidWorks的材質(zhì)信息。在SolidWorks中的零件文檔有材料信息，實體(Body)有材質(zhì)信息蛤迎，面有材質(zhì)信息。此處的材質(zhì)信息包含顏色丝里，光澤度等等。
處理這些材質(zhì)信息后才能讓轉(zhuǎn)換出來的文檔和SolidWorks中的文檔看起來相似体谒。
4.2 材質(zhì)信息
- 在SolidWorks中杯聚，IPartDoc,IFace2,IBody都具有MaterialPropertyValue的屬性。這個屬性會返回一個數(shù)組抒痒。
[ R, G, B, Ambient, Diffuse, Specular, Shininess, Transparency, Emission ]
- 在這里我們使用一個SharpglTF中MaterialBulider對象來構(gòu)造一個的材質(zhì)對象
public MaterialBuilder MaterialBuilder
{
get
{
if (FaceMaterialValue != null)
{
_MaterialBuilder = new MaterialBuilder()
.WithDoubleSide(true)
.WithChannelParam(KnownChannels.Normal, new System.Numerics.Vector4(
Convert.ToSingle(FaceMaterialValue[0]),
Convert.ToSingle(FaceMaterialValue[1]),
Convert.ToSingle(FaceMaterialValue[2]),
1));
}
return _MaterialBuilder;
}
}
4.3 存儲零件幌绍，實體，面的材質(zhì)和幾何信息

- 我們用這樣一個數(shù)據(jù)結(jié)構(gòu)來描述一個SolidWorks零件或者轉(zhuǎn)配體故响。在轉(zhuǎn)換中將其轉(zhuǎn)換為SharpglTF的一個sence對象傀广，在輸出為gltf格式。
