函数: lineSegmentTriangle()
lineSegmentTriangle(
v0:Cartesian3,v1:Cartesian3,p0:Cartesian3,p1:Cartesian3,p2:Cartesian3,cullBackFaces?:boolean,result?:Cartesian3):Cartesian3
Computes the intersection of a line segment and a triangle.
参数
v0
The an end point of the line segment.
v1
The other end point of the line segment.
p0
The first vertex of the triangle.
p1
The second vertex of the triangle.
p2
The third vertex of the triangle.
cullBackFaces?
boolean
If <code>true</code>, will only compute an intersection with the front face of the triangle and return undefined for intersections with the back face.
result?
The <code>Cartesian3</code> onto which to store the result.
返回
The intersection point or undefined if there is no intersections.
