DXSceneCalculateCameraPlanes(Matrix, Boolean, Boolean, Vector3, Boolean, Single, Single) Method

CalculateCameraPlanes sets the zNear and zFar parameters to camera near plane distance and camera far plane distance. When adjustValues Boolean parameter is true, the zNear and zFar values are slightly adjusted to increase the distance between zNear and zFar (recommended). CalculateCameraPlanes returns false if the calculated values are not correct (are 0, NaN or Infinity). This can happen when camera's matrices are not set.

Namespace: Ab3d.DirectX
Assembly: Ab3d.DXEngine (in Ab3d.DXEngine.dll) Version: 7.0.8865.1045
Syntax
C#
Copy
public static bool CalculateCameraPlanes(
	ref Matrix viewMatrix,
	bool isOrthographicProjection,
	bool isRightHandedCoordinateSystem,
	Vector3[] boundingCorners,
	bool adjustValues,
	out float zNear,
	out float zFar
)

Parameters

viewMatrix  Matrix
viewMatrix
isOrthographicProjection  Boolean
true if camera is using Orthographic projection, false for Perspective projection
isRightHandedCoordinateSystem  Boolean
true when using right handed coordinate system (true for DXEngine)
boundingCorners  Vector3
array of Vector3 elements that represents corner positions for BoundingBox (use BoundingBox.GetCorners to get this array)
adjustValues  Boolean
When adjustValues Boolean parameter is true, the zNear and zFar values are slightly adjusted to increase the distance between zNear and zFar (recommended)
zNear  Single
out camera near plane distance
zFar  Single
out camera far plane distance

Return Value

Boolean
returns false if the calculated values are not correct (are 0, NaN or Infinity). This can happen when camera's matrices are not set.
