static constexpr Matrix43 SRL::Math::Types::Matrix43::CreateLookAt ( const Vector3D & eye, const Vector3D & target, const Vector3D & up = Vector3D::UnitY() )

inlinestaticconstexpr

Creates a look-at matrix for positioning a camera in 3D space.

This function generates a view matrix that can be used to position a camera looking at a specific target point from a given eye position, with an up vector to define the camera's vertical orientation.

Template Parameters

P	The precision level for calculations, defaulting to Standard.

Parameters

eye	The position of the camera in world coordinates.
target	The point in world space that the camera is looking at.
up	The up vector, which defines the camera's vertical direction (default is Vector3D::UnitY()).

Returns

A Matrix43 representing the look-at transformation.

Note

This function assumes that the up vector is not collinear with the look vector.

Matrix43 viewMatrix = Matrix43::CreateLookAt(
    Vector3D(0.0, 0.0, 5.0),  // Eye position
    Vector3D(0.0, 0.0, 0.0),  // Target position
    Vector3D::UnitY()            // Up vector
);

This function is used to create a view matrix that can be used to position a camera in 3D space. The resulting matrix can be used to transform points from world space to the camera's local space.
