Description

Bindings to rcamera (rcamera.h)

These were rewritten in Haskell instead of binding to C. All the functions are pure.

Documentation

getCameraForward :: Camera -> Vector3 Source #

The camera's forward vector (normalized)

getCameraUp :: Camera -> Vector3 Source #

The camera's up vector (normalized)

getCameraRight :: Camera -> Vector3 Source #

The camera's right vector (normalized)

cameraMove :: Camera -> Vector3 -> Camera Source #

Move the camera by a specific vector

cameraMoveForward Source #

Arguments

:: Camera
-> Float	Distance to move
-> Bool	Move in world plane (i.e. no vertical movement if enabled)
-> Camera

Move the camera in its forward direction

cameraMoveUp Source #

Arguments

:: Camera
-> Float	Distance to move
-> Camera

Move the camera in its up direction

cameraMoveRight Source #

Arguments

:: Camera
-> Float	Distance to move
-> Bool	Move in world plane (i.e. no vertical movement if enabled)
-> Camera

Move the camera in its right direction

cameraRotate Source #

Arguments

:: Camera
-> Vector3	Axis of rotation
-> Float	Angle to rotate by
-> Bool	Rotate around target (if false, the camera rotates around its position)
-> Camera

Rotate the camera using an axis and angle

cameraYaw Source #

Arguments

:: Camera
-> Float	Angle in radians
-> Bool	Rotate around target (if false, the camera rotates around its position)
-> Camera

Rotate the camera around its up vector. Yaw is "looking left and right".

cameraPitch Source #

Arguments

:: Camera
-> Float	Angle in radians
-> Bool	Lock view (prevents camera overrotation, aka "somersaults")
-> Bool	Rotate around target (if false, the camera rotates around its position)
-> Bool	Rotate the camera's up vector to match the new pitch
-> Camera

Rotate the camera around its right vector. Pitch is "looking up and down".

cameraRoll Source #

Arguments

:: Camera
-> Float	Angle in radians
-> Camera

Rotates the camera around its forward vector. Roll is "turning your head sideways to the left or right".

getCameraViewMatrix :: Camera -> Matrix Source #

View matrix from camera

getCameraProjectionMatrix Source #

Arguments

:: Camera
-> Float	Aspect ratio
-> Float	Near clipping plane distance (recommended: 0.01)
-> Float	Far clipping plane distance (recommended: 1000)
-> Matrix

Projection matrix from camera
