Struct gemini_engine::elements3d::view3d::transform3d::Transform3D

pub struct Transform3D {
    pub translation: Vec3D,
    pub rotation: Vec3D,
    pub scale: Vec3D,
}

The Transform3D struct is used to manipulate the position of objects in 3D space

Fields

translation: Vec3D

The position of the object in 3D space

rotation: Vec3D

The rotation of the object, applied in radians

scale: Vec3D

The object’s scale
