pynodegl is the Python binding for libnodegl. It is
automatically generated from to the libnodegl node specifications file. For
detailed information on how the pynodegl binding is created, refer to the
corresponding pynodegl explanation.
In order to use the pynodegl, you will have to rely on the reference node
specifications. The Python binding classes and parameters are
directly named after the names found in the specifications. For example, to get
an instance of a Group, one has to instantiate a Group
such as g = Group(children=(r1, r2, r3)).
In the constructors, the expected Python parameter types follow this table:
| Parameter type | Python type | Example |
|---|---|---|
*Dict |
dict |
render = Render(geometry, frag_resources={'tex0': t0, 'tex1': t1}) |
vec*, mat*, *List |
Iterable such as tuple or list |
scale = Scale(child, factors=(0.3, 1.2, 1.0)) |
| All the others | - |
circle = Circle(radius=0.5, npoints=128) |
Every parameter also has a setter method associated, named according to the parameter name and its type.
| Parameter type | Node method | Python type | Example |
|---|---|---|---|
*Dict |
update_<param>(self, <param>) |
dict or named arguments |
render.update_frag_resources(tex0=t0, tex1=t1) |
*List |
add_<param>(self, *<param>) |
positional arguments | group.add_children(r1, r2, r3) |
| All the others | set_<param>(self, <param>) |
positional arguments | camera.set_center(1.0, -1.0, 0.5) |
