TriMesh.LoadVerticesFromBytes

TriMesh.LoadVerticesFromBytes method

从字节加载顶点，字节长度必须是顶点大小的整数倍。

public void LoadVerticesFromBytes(byte[] verticesInBytes)
参数类型描述
verticesInBytesByte[]

异常

异常条件
ArgumentNullException
ArgumentException

示例

以下代码展示了如何创建一个空的 TriMesh 并手动从原始字节加载顶点。

var indices = new int[] { 0,  1,  2 };
var vertices = new byte[]{
    0, 0, 0, 191,
    0, 0, 0, 0,
    0, 0, 0, 191,
    0, 0, 0, 191,
    0, 0, 0, 0,
    0, 0, 0, 63,
    0, 0, 0, 63,
    0, 0, 0, 0,
    0, 0, 0, 63
};
VertexDeclaration vd = new VertexDeclaration();
vd.AddField(VertexFieldDataType.FVector3, VertexFieldSemantic.Position);
//使用指定的顶点声明创建一个空的 TriMesh
var triMesh = new TriMesh("", vd);
//直接从字节加载顶点
triMesh.LoadVerticesFromBytes(vertices);
triMesh.AddTriangle(0, 1, 2);

int[] indices = new int[] { 0,  1,  2 };
byte[] vertices = new byte[]{
    0, 0, 0, 191,
    0, 0, 0, 0,
    0, 0, 0, 191,
    0, 0, 0, 191,
    0, 0, 0, 0,
    0, 0, 0, 63,
    0, 0, 0, 63,
    0, 0, 0, 0,
    0, 0, 0, 63
};
VertexDeclaration vd = new VertexDeclaration();
vd.addField(VertexFieldDataType.F_VECTOR3, VertexFieldSemantic.POSITION);
//使用指定的顶点声明创建一个空的 TriMesh
var triMesh = new TriMesh("", vd);
//直接从字节加载顶点
triMesh.loadVerticesFromBytes(vertices);
triMesh.addTriangle(0, 1, 2);
