◆ base()

Vector3f EGG::Matrix34f::base ( size_t col ) const

inlinenodiscard0x80537B80

Get a particular column from a matrix.

Definition at line 70 of file Matrix.hh.

◆ inverseTo33()

void EGG::Matrix34f::inverseTo33 ( Matrix34f & out ) const

0x8022F90C

Inverts the 3x3 portion of the 3x4 matrix.

Unlike a typical matrix inversion, if the determinant is 0, then this function returns the identity matrix.

Definition at line 262 of file Matrix.cc.

◆ makeOrthonormalBasis()

void EGG::Matrix34f::makeOrthonormalBasis	(	const Vector3f &	forward,
		const Vector3f &	up )

0x805AE7B4

Sets a 3x3 orthonormal basis for a local coordinate system.

In a vector's orthogonal space, there are infinitely many vector pairs orthogonal to each other. To specify a particular pair and create a local coordinate system, a reference up vector from an existing coordinate system is provided.

Parameters

forward	The forward axis of the local coordinate system.
up	The reference up axis from an existing coordinate system.
