UKismetMathLibrary::Matrix_GetFrustumRightPlane

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticBlueprintPure

Description

Extracts the right clipping plane from a view-projection matrix. Returns false if extraction fails.

Caveats & Gotchas

• The plane normal points inward (toward the interior of the frustum), not outward — this is the opposite convention from some other engines.
• For asymmetric frustums (e.g. VR or off-axis projections) the right and left plane distances will differ; don't assume symmetry.

Signature

static UE_INL_API bool Matrix_GetFrustumRightPlane(const FMatrix& M, FPlane& OutPlane)

Parameters

Name	Type	Description	Default
M	const FMatrix&	The view-projection matrix to extract the right frustum plane from.	—
OutPlane	FPlane&	The extracted right plane of the frustum.	—

Return Type

bool

Example

Test if a point is inside the right frustum boundary C++

FPlane RightPlane;
if (UKismetMathLibrary::Matrix_GetFrustumRightPlane(ViewProjMatrix, RightPlane))
{
    bool bInsideRight = RightPlane.PlaneDot(TestPoint) >= 0.0f;
}
