simvx.editor.panels.viewport3d

3D Viewport Panel – Interactive 3D scene view with camera, grid, gizmos.

Renders the edited scene through an EditorCamera3D with orbit/pan/zoom controls, draws a reference grid on the XZ plane, and provides gizmo-based transform manipulation for the selected node.

class simvx.editor.panels.viewport3d.Viewport3DPanel(editor_state: simvx.editor.state.EditorState, **kwargs)

Bases: simvx.core.Control

Interactive 3D viewport panel for the SimVX editor.

Features:

• Orbit / pan / zoom camera controls (middle-drag, shift+middle, scroll)

• Laptop-friendly: Alt+left-drag = orbit, Alt+Shift+left-drag = pan

• XZ ground grid (major + minor lines)

• RGB axis indicator in corner

• Object selection via ray picking

• Gizmo overlay for translate / rotate / scale

• Undo-integrated gizmo interactions

• Camera info overlay

Initialization

process(dt: float)

Per-frame update: keep gizmo position in sync with selection.

draw(renderer)

Main draw entry point called each frame by the editor.

handle_scroll(delta: float)

External scroll event forwarding (e.g. from GLFW callback).

set_viewport_size(width: float, height: float)

Resize the viewport panel.
