- Description
The TDx_3DDevice::GetClipPlane() method will retrieve the coefficients of the user defined clipping plane for this device.
The plane equation exists in world space and is set using TDx_3DDevice::SetClipPlane().
The coefficients returned take the form of the general plane equation.
Eg: If values A, B, C, and D were returned in PlaneEquation they would fit the general plane equation such that Ax + By + Cz + D = 0.
A homogeneous coordinate point (x, y, z, w) will be visible where Ax + By + Cz + Dw >= 0.
If the method call fails, the OnError event will be triggered with one of the following values:
DDERR_INVALIDPARAMS
- Parameters
Index
The Index parameter identifies the clipping plane for which the coefficients are being retrieved.
PlaneEquation
The PlaneEquation parameter references a 4 element floating point array for holding the coefficients if this method returns successfully.
