Public / Constructors

Camera

public constructor Camera → (1)

handedness opt : CartesianHandedness = CartesianHandedness.RightHanded

The coordinate system handedness.

Creates a new instance of Camera.

Public / Methods

FromMatrix

public method FromMatrix → (2)

view in : Mat4D

The combined model-view transformation matrix.

projection in : Mat4D

The projection matrix.

Updates this camera view from the view and projection matrices.

LookAt

public method LookAt → (2)

target in : Vec3D

The target to look at.

up in : Vec3D

The up direction.

returns → bool

true if the camera has been updated, false if not because the given target and/or up direction are invalid.

Lets the scene camera look at the given target from its current position.

MatrixPerspective

[Pure]
public method MatrixPerspective → (5)

width in : int32

[>0]
The viewport width.

height in : int32

[>0]
The viewport height.

nearAtZero in : bool

When true, the near clipping plane will be mapped to 0 in clip-space (e.g. Direct3D); when false it will be mapped to -1 (e.g. OpenGL).

zNear opt : float64 = 0.001

Z-value of near clipping plane.

zFar opt : float64 = 20000000

[Pure]
public method MatrixView → ()

returns → Mat4D

The view matrix.

Creates a view matrix for the current camera settings.

MatrixViewLocal

[Pure]
public method MatrixViewLocal → ()

returns → Mat4D

The view matrix.
