API¶

class simvx.core.nodes_3d.Node3D(position=None, rotation=None, scale=None, **kwargs)¶

Bases: simvx.core.node.Node

3D spatial node with position, rotation, and scale.

Extends Node with a 3D transform and cached global-transform propagation through the hierarchy. All 3D objects – meshes, cameras, lights – inherit from this.

Attributes: position: Local position as Vec3. rotation: Local rotation as Quat (quaternion). scale: Local scale as Vec3 (default (1, 1, 1)).

Example::

cube = Node3D(position=(0, 2, -5), name="Cube")
cube.rotate_y(math.radians(45))
print(cube.forward)  # unit vector along the local -Z axis

class simvx.core.nodes_3d.Camera3D(position=None, rotation=None, scale=None, **kwargs)¶

Bases: simvx.core.nodes_3d.Node3D

3D perspective camera providing view and projection matrices.

The first Camera3D found in the scene tree is used by the renderer. Position and orientation are inherited from Node3D; the camera adds projection parameters (field of view, clip planes).

Attributes: fov: Vertical field of view in degrees (1 – 179). near: Near clip plane distance. far: Far clip plane distance.

Example::

camera = Camera3D(position=(0, 5, 10), name="MainCamera")
camera.look_at((0, 0, 0))
camera.fov = 75.0
