RotateX()

Matrix33 & SRL::Math::Types::Matrix33::RotateX ( const Angle & angleX )

inlineconstexprinherited

Apply X-axis rotation to the current matrix.

Modifies the current matrix by applying a rotation around the X-axis. This is equivalent to multiplying the current matrix by a rotation matrix.

The X-axis rotation matrix is: | 1 0 0 | | 0 cos(θ) -sin(θ) | | 0 sin(θ) cos(θ) |

Parameters

angleX

Rotation angle around X-axis.

Returns

Reference to this matrix after rotation.

Note

This is ideal for continuous transformations like animation as it modifies the existing matrix rather than creating a new one.

Matrix33 transform = Matrix33::Identity();
transform.RotateX(Angle::FromDegrees(45)); // Rotate 45° around X
