Math::Matrix3 struct
#include <Spore ModAPI/Spore/MathUtils.h>

A 3x3 matrix.

Public static functions

static auto FromEuler(const Vector3& angles) -> Matrix3: Builds a 3x3 rotation matrix equivalent to the euler angles provided.
static auto FromAxisAngle(const Vector3& axis, float angle) -> Matrix3: Builds a 3x3 rotation matrix that rotates angle radians around the given axis.
static auto LookAt(const Vector3& position, const Vector3& target, const Vector3& up = Z_AXIS) -> Matrix3: Builds a rotation matrix that can be used in cameras, for a camera at position looking towards target.

auto Row(int index) const -> Vector3
auto Column(int index) const -> Vector3
auto SetIdentity() -> Matrix3&: Turns this matrix into the identity matrix (1.0s in the diagonal, everything else 0.0s).
auto ToEuler() const -> Vector3: Returns the euler angles (in radians) equivalent to the rotation of this matrix.
auto ToQuaternion() const -> Quaternion: Returns a Quaternion that represents the same rotation as this matrix.
auto Transposed() const -> Matrix3: Returns the transpose of this matrix, switching the rows and columns. transposed[i][j] = matrix[j][i]

Builds a 3x3 rotation matrix equivalent to the euler angles provided.

Parameters
angles	The euler angles, in radians.

The euler angles must be in radians, and each value represents the rotation around the X, Y and Z axes respectively.

Builds a 3x3 rotation matrix that rotates angle radians around the given axis.

Parameters
axis	The axis of rotation, which stays fixed.
angle	The angle, in radians.

This is equivalent to Quaternion::FromRotation(axis, angle).ToMatrix().

Builds a rotation matrix that can be used in cameras, for a camera at position looking towards target.

Parameters
position	The "eye" position
target	The position where the "eye" is looking at
up	[Optional] The up vector, Z axis by default.

Optionally, the vector that represents the up direction in the world (which usually is the Z axis) can be specified.

This method might give unexpected results if target and position are aligned.

Turns this matrix into the identity matrix (1.0s in the diagonal, everything else 0.0s).

Multiplying a matrix/vector with an identity matrix has no effect.

Returns the euler angles (in radians) equivalent to the rotation of this matrix.

The euler angles are a vector of 3 values that represent the rotation around the X, Y and Z axes respectively.
