jit.matrix

The Jitter Matrix!

Description

The jit.matrix object is a named matrix which may be used for data storage and retrieval, resampling, and matrix type and planecount conversion operations.

Examples

Attributes

adapt [int]

Matrix adaptation flag (default = 0 if matrix arguments are present, otherwise 1) When the flag is set, the jit.matrix object will adapt to the incoming matrix planecount, type, and dimensions.

Messages

bang

Outputs the currently stored matrix.

int

Arguments

values [list]
Sets all cells to the value specified by value(s) and output the data. Position is specified of a list whose length is equal to the number of dimensions (dimcount).

float

Arguments

values [list]
Sets all cells to the value specified by value(s) and output the data. Value is specified as a list whose length is equal to the number of dimensions (dimcount).

list

Arguments

values [list]
Sets all cells to the value specified by value(s) and output the data. Position is specified of a list whose length is equal to the number of dimensions (dimcount).

clear

Sets all matrix values to zero.

exportimage

Arguments

filename [symbol]
file-type [symbol]
Export the current frame as an image file with the name specified by the first argument. The second argument sets the file type (default = png). Available file types are png, tiff, and jpeg.
You can use the Max Preferences to specify a default image resolution for png image types.

exportmovie

Arguments

filename [symbol]
FPS [float]
codec [symbol]
quality [symbol]
timescale [int]
Exports a matrix as a movie. The exportmovie message takes an optional argument to specify a file name. If no filename is specified, a file dialog will open to let you choose a file.
See the jit.record object for information on the write arguments and their default values.

exprfill

Arguments

plane [int]
expression [symbol]
Evaluates expression to fill the matrix. If a plane argument is provided, the expression is applied to a single plane. Otherwise, it is applied to all planes in the matrix. See jit.expr for more information on expressions. Unlike the jit.expr object, there is no support for providing multiple expressions to fill multiple planes at once with different expressions. Call this method multiple times once for each plane you wish to fill.

fillplane

Arguments

plane [int]
value [int]
The word fillplane, followed by an integer that specifies a plane number and a value, will fill the specified plane with the single value.

getcell

Arguments

position [list]
Sends the value(s) in the cell specified by position out the right outlet of the object as a list in the form cell cell-position0 ... cell-positionN val plane0-value ... planeN-value .

importmovie

Arguments

filename [symbol]
time-offset [int]
Imports a movie into the matrix. If no filename is specified, a file dialog will open to let you choose a file. The time-offset argument may be used to set a time offset for the movie being imported (the default is 0).

jit_gl_texture

Arguments

texture-name [symbol]
Copies the texture specified by texture-name to the matrix.

op

The word op, followed by the name of a jit.op object operator and a set of values, is equivalent to including a jit.op object with the specified operator set as an attribute and this jit.matrix object specified as the output matrix. The additional value arguments may either be a matrix name or a constant. If only one value argument is provided, this matrix is considered both the output and the left operand. For example, "op + foo bar" is equivalent to the operation thismatrix = foo + bar, and "op * 0.5" is equivalent to the operation thismatrix = thismatrix * 0.5.

read

Arguments

filename [symbol]
Reads Jitter binary data files (.jxf) into a matrix set. If no filename is specified, a file dialog will open to let you choose a file.

setall

Arguments

values [list]
Sets all cells to the value specified by value(s). Position is specified of a list whose length is equal to the number of dimensions (dimcount).

setcell

Arguments

position [list]
group (optional)
plane [literal]
plane-number [int]
end group
val [literal]
values [list]
Sets the cell specified by position to the value specified by value. Position is specified of a list whose length is equal to the number of dimensions (dimcount). The optional arguments plane plane-number can be used to specify a plane. If a plane is specified, value should be a single number, otherwise it should be a list of numbers of size planecount - 1.

setcell1d

The word setcell1d, followed by a number specifying an x coordinate and a list of values, is similar to the setcell message but without the need to use a "val" token to separate the coordinates from the value since the dimension count (1) is fixed.

setcell2d

The word setcell2d, followed by a pair of numbers specifying x and y coordinates and a list of values, is similar to the setcell message but without the need to use a "val" token to separate the coordinates from the value since the dimension count (2) is fixed.

setcell3d

The word setcell3d, followed by three numbers specifying x , y , and z coordinates and a list of values, is similar to the setcell message but without the need to use a "val" token to separate the coordinates from the value since the dimension count (3) is fixed.

setplane1d

The word setplane1d, followed by a number specifying an x coordinate, a number specifying a plane, and a value, is similar to the setcell message but without the need to use a "val" token to separate the coordinates from the value since the dimension count (1) is fixed, or use the "plane" token to specify which plane to set.

setplane2d

The word setplane2d, followed by a pair of numbers specifying x and y coordinates, a number specifying a plane, and a value, is similar to the setcell message but without the need to use a "val" token to separate the coordinates from the value since the dimension count (2) is fixed, or use the "plane" token to specify which plane to set.

setplane3d

The word setplane3d, followed by three numbers specifying x , y , and z coordinates, a number specifying a plane, and a value, is similar to the setcell message but without the need to use a "val" token to separate the coordinates from the value since the dimension count (1) is fixed, or use the "plane" token to specify which plane to set.

val

Arguments

values [list]
Sets all cells to the value specified by value(s). Position is specified of a list whose length is equal to the number of dimensions (dimcount) and outputs the data.

write

Arguments

filename [symbol]
Writes matrix set as a Jitter binary data file (.jxf). If no filename is specified, a file dialog will open to let you choose a file.
