alloc

matrixAlloc Source #

Arguments

:: (HasCallStack, MonadIO m)
=> m Matrix	Returns: the newly allocated `Matrix`

Allocates enough memory to hold a Matrix.

Since: 1.12

free

matrixFree Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Maybe Matrix	`matrix`: a `Matrix`
-> m ()

Frees the memory allocated by matrixAlloc.

Since: 1.12

initFromArray

matrixInitFromArray Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Matrix	`matrix`: a `Matrix`
-> [Float]	`values`: a C array of 16 floating point values, representing a 4x4 matrix, with column-major order
-> m Matrix	Returns: the initialzed `Matrix`

Initializes matrix with the contents of a C array of floating point values.

Since: 1.12

initFromMatrix

matrixInitFromMatrix Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Matrix	`a`: the `Matrix` to initialize
-> Matrix	`b`: the `Matrix` to copy
-> m Matrix	Returns: the initialized `Matrix`

Initializes the Matrix a with the contents of the Matrix b.

Since: 1.12

initIdentity

matrixInitIdentity Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Matrix	`matrix`: a `Matrix`
-> m Matrix	Returns: the initialized `Matrix`

Initializes matrix with the identity matrix, i.e.:

 .xx = 1.0, .xy = 0.0, .xz = 0.0, .xw = 0.0
 .yx = 0.0, .yy = 1.0, .yz = 0.0, .yw = 0.0
 .zx = 0.0, .zy = 0.0, .zz = 1.0, .zw = 0.0
 .wx = 0.0, .wy = 0.0, .wz = 0.0, .ww = 1.0
