Detailed Description

Extended RRMatrix3x4, has built-in inverse matrix and several functions that use it.

Constructor & Destructor Documentation

◆ RRMatrix3x4Ex() [1/2]

rr::RRMatrix3x4Ex::RRMatrix3x4Ex ( )
inline

◆ RRMatrix3x4Ex() [2/2]

rr::RRMatrix3x4Ex::RRMatrix3x4Ex ( const RRMatrix3x4 &  a)
explicit

Member Function Documentation

◆ updateInverse()

void rr::RRMatrix3x4Ex::updateInverse ( )

Updates inverse and scaleSign from m. To be called each time you modify matrix.

◆ transformNormal()

void rr::RRMatrix3x4Ex::transformNormal ( RRVec3 &  a) const

Transforms normal in 3d space. Result is not normalized.

Unlike transformDirection(), transformNormal() ensures that normals perpendicular to surface stay perpendicular even for matrices with non-uniform scale.

◆ getTransformedNormal()

RRVec3 rr::RRMatrix3x4Ex::getTransformedNormal ( const RRVec3 &  a) const

Returns normal transformed in 3d space. Result is not normalized.

Unlike getTransformedDirection(), getTransformedNormal() ensures that normals perpendicular to surface stay perpendicular even for matrices with non-uniform scale.

◆ transformPlane()

void rr::RRMatrix3x4Ex::transformPlane ( RRVec4 &  a) const

Transforms plane in 3d space.

◆ getTransformedPlane()

RRVec4 rr::RRMatrix3x4Ex::getTransformedPlane ( const RRVec4 &  a) const

Returns plane transformed in 3d space.

Member Data Documentation

◆ inverse

RRMatrix3x4 rr::RRMatrix3x4Ex::inverse

Inverse matrix.

◆ scaleSign

RRReal rr::RRMatrix3x4Ex::scaleSign

-1 if scale is negative, 1 if positive.
