Public Sub ProjectFromScreen ( 
	ByRef src As SbVec3f,
	<OutAttribute> ByRef dst As SbVec3f
)

public:
void ProjectFromScreen(
	SbVec3f% src, 
	[OutAttribute] SbVec3f% dst
)

member ProjectFromScreen : 
        src : SbVec3f byref * 
        dst : SbVec3f byref -> unit 

Parameters

src

Type: OIV.InventorSbVec3f
Input point in normalized screen coordinates.

dst

Type: OIV.InventorSbVec3f
Output point in world coordinates.

The resulting Z coordinate represents the normalized distance at which the point would be back projected, ranging from 0 at the near clipping plane to 1 at the far clipping plane. This method is simply the inverse of ProjectToScreen(SbVec3f, SbVec3f). See also GetPlanePoint(Single, SbVec2f).

Note: This is a convenience function that calls the GetMatrix method and apply Inverse on it, then transforms the point. The GetMatrix and Inverse calls are somewhat expensive, so if you need to project a large number of points you should call these methods just once and apply the matrix to each point using MultVecMatrix(SbVec3f, SbVec3f).
