Display functions

type Render = forall a b. (Arrays a, Arrays b) => (Acc a -> Acc b) -> a -> b Source #

The type for executing Accelerate computations. This matches the run1 style of executing programs.

Some variants of the display functions take an argument of this type, which determine how computations are executed.

data Display #

Describes how Gloss should display its output.

Constructors

InWindow String (Int, Int) (Int, Int)	Display in a window with the given name, size and position.
FullScreen	Display full screen.

animateArrayWith Source #

Arguments

:: Render	Method to render the array (backend `run1` function to use)
-> Display	Display mode
-> (Int, Int)	Number of pixels to draw per point
-> (Exp Float -> Acc (Array DIM2 Colour))	A function to construct an array of colours. The function should return an array of the same extent every time it is applied. It is passed the time in seconds since the program started.
-> IO ()

Animate a bitmap generated by an Accelerate computation, specifying the backend used to render the image.

animateArrayIOWith Source #

Arguments

:: Arrays world
=> Render	Method to render the array (backend `run1` function)
-> Display	Display mode
-> (Int, Int)	Number of pixels to draw per point
-> (Float -> IO world)	Extract world from time in seconds since the program started
-> (Acc world -> Acc (Array DIM2 Colour))	A function to construct an array of colours. The function should return an array of the same extent every time it is applied. It is passed the world
-> IO ()

Animate a bitmap generated by an Accelerate computation and IO actions, specifying the backend used to render the image.

playArrayWith Source #

Arguments

:: Arrays world
=> Render	Method to render the world (backend `run1` function)
-> Display	Display mode
-> (Int, Int)	Number of pixels to draw per point
-> Int	Number of simulation steps to take for each second of real time
-> state	The initial state
-> (state -> world)	Extract the world state
-> (Acc world -> Acc (Array DIM2 Colour))	Compute the colour of the world
-> (Event -> state -> state)	Handle input events
-> (Float -> state -> state)	Step the world one iteration. It is passed the time in seconds since the program started.
-> IO ()

Play with a bitmap generated by an Accelerate computation, specifying the method used to render the world.

playArrayIOWith Source #

Arguments

:: Arrays world
=> Render	Method to render the world (backend `run1` function)
-> Display	Display mode
-> (Int, Int)	Number of pixels to draw per point
-> Int	Number of simulation steps to take for each second of real time
-> state	The initial state
-> (state -> IO world)	Extract the world state
-> (Acc world -> Acc (Array DIM2 Colour))	Compute the colour of the world
-> (Event -> state -> IO state)	Handle input events
-> (Float -> state -> IO state)	Step the world one iteration. It is passed the time in seconds since the program started.
-> IO ()

Play with a bitmap generated by an Accelerate computation and IO actions, specifying the method used to render the world.

Picture creation

makePicture Source #

Arguments

:: Arrays world
=> Render	method to compute the image
-> Int	pixel width
-> Int	pixel height
-> (Acc world -> Acc (Array DIM2 Colour))	function to create the image
-> world -> Picture	new function that generates the picture

Lift an Accelerate computation from a world to an image into a real Haskell-land function that executes the computation of the image and wraps it as a Gloss picture ready for display.
