inline

Get the vector pointing to the right (positive X axis)

Returns: Right vector

◆ rotate()

void spatium::gfx3d::Transform::rotate ( const geom3d::Vector3 & euler )

inline

Rotate (relative to self/object space)

Parameters

[in] euler Degrees around x, y and z axis

Todo:: This doesn't work... Use TRS?

◆ rotation()

geom3d::Vector3 spatium::gfx3d::Transform::rotation ( ) const

inline

Get the rotation in world space.

Returns: Rotation in euler angles

Todo:: Check if should each column should be scaled first?
