class Colord.Vec3

add(src2, dest)

Parameters:

• src2 (Colord.Vec3) – the other source

• dest (Colord.Vec3) – the destination

Adds two vector quantaties The arguments src and dest can be the same value.

clear()

Clears a vector, setting all it’s values to zero.

copy(dest)

Parameters:

dest (Colord.Vec3) – the destination

Copies the vector into another vector. The arguments self and dest cannot be the same value.

get_data()

Returns:

the pointer to the data segment.

Return type:

float

Gets the raw data for the vector.

init(v0, v1, v2)

Parameters:

• v0 (float) – component value

• v1 (float) – component value

• v2 (float) – component value

Initialises a vector.

scalar_multiply(value, dest)

Parameters:

• value (float) – the scalar multiplier

• dest (Colord.Vec3) – the destination

Multiplies a vector with a scalar. The arguments self and dest can be the same value.

squared_error(src2)

Parameters:

src2 (Colord.Vec3) – another vector source

Returns:

the floating point MSE.

Return type:

float

Gets the mean squared error for a pair of vectors

subtract(src2, dest)

Parameters:

• src2 (Colord.Vec3) – the other source

• dest (Colord.Vec3) – the destination

Subtracts one vector quantity from another The arguments src and dest can be the same value.

to_string()

Returns:

the string. Free with GLib.free()

Return type:

str

Obtains a string representaton of a vector.
