This API is experimental
Its behavior may change in a future version of p5.js.
Creates a 4x4 matrix inside a p5.strands shader callback.
mat4() is the same function as transform3D(), named the way it is in GLSL.
Passing a 3x3 matrix to mat4() extends it with the identity matrix, which turns a 2D transform into a 3D one that leaves the z-axis alone.
Note: mat4() can only be used inside a p5.strands shader callback.
Examples
Syntax
mat4(values1, values2, ..., valuesn)
Parameters
values1, ..., valuesn
Number: nothing for the identity matrix, one number, one matrix, 4 column vectors, or 16 values in column-major order.
Returns
a 4x4 matrix.
