Comfortable camera navigation helper for WorldViz Vizard 8

GoodNavigate

GoodNavigate is a camera navigation helper package for WorldViz Vizard 8. It adds comfortable editor-style camera controls to a Vizard scene with one call.

This package depends on Vizard's viz and vizact modules, so it is intended to run inside a Vizard 8 Python environment. It is not a standalone Python camera library.

Features

• Mouse-look camera rotation
• WASD camera movement
• Height-locked horizontal movement mode
• F key toggle for height lock
• Customizable movement keys
• Runtime speed and mouse sensitivity setters
• Current status dictionary
• Stops movement when the Vizard window loses focus
• Space to move up
• C to move down
• Shift for temporary fast movement
• Mouse wheel speed adjustment
• Center-screen speed multiplier overlay
• Rounded gray overlay background
• No automatic viz.go() when imported
• pause(), resume(), and disable() control helpers

Installation

Install it into the Python environment used by Vizard 8.

python -m pip install git+https://github.com/cuber244/goodnavigate.git

If python is not Vizard's Python, run pip through the Vizard Python executable instead. The exact path depends on your PC, but the command will look like this:

"C:\Path\To\Vizard8\python.exe" -m pip install git+https://github.com/cuber244/goodnavigate.git

After the package is published to PyPI, installation becomes shorter:

python -m pip install goodnavigate

Basic Usage

Use the lowercase package name for new Vizard scripts.

import viz
import goodnavigate

viz.go()

goodnavigate.enable()

Importing goodnavigate does not start Vizard and does not add scene objects. Call goodnavigate.enable() after viz.go() in the script that owns the scene.

For compatibility, import GoodNavigate is also included after pip installation:

import viz
import GoodNavigate

viz.go()
GoodNavigate.enable()

Controls

Input	Action
Left mouse drag	Horizontal yaw rotation, pitch is leveled when drag starts
Right mouse drag	Free-look yaw and pitch rotation
W / S	Move forward / backward
A / D	Move left / right
Space	Move up
C	Move down
Shift	Temporary fast movement
Mouse wheel	Change movement speed multiplier
F	Toggle height lock

F is handled through Vizard's key-down callback when available. If that callback is unavailable, GoodNavigate falls back to polling the key state each frame.

Height Lock

Height lock is enabled by default.

When height lock is enabled, WASD movement stays horizontal even if the camera is looking up or down. This is useful for walking-style navigation.

When height lock is disabled, W and S move forward and backward along the camera's pitch direction. Looking up and pressing W moves upward and forward; looking down and pressing W moves downward and forward. A and D strafe relative to the current yaw.

Toggle height lock while running:

# Press F in the Vizard window

Configure the initial mode:

goodnavigate.enable(height_lock=True)   # default
goodnavigate.enable(height_lock=False)  # free fly movement

Programmatic control:

navigator = goodnavigate.enable()

navigator.set_height_lock(False)
navigator.toggle_height_lock()
locked = navigator.is_height_locked()

Custom Keys

You can customize movement keys when enabling GoodNavigate.

goodnavigate.enable(
    forward_key='i',
    backward_key='k',
    left_key='j',
    right_key='l',
    up_key='u',
    down_key='o',
    toggle_height_lock_key='h',
)

Temporary fast movement keys can also be changed. Pass a tuple or list of Vizard key constants or key strings.

goodnavigate.enable(fast_keys=(viz.KEY_SHIFT_L, viz.KEY_SHIFT_R))

You can change keys after enabling:

navigator = goodnavigate.enable()
navigator.set_keys(forward='i', backward='k', toggle_height_lock='h')

Speed Adjustment

The mouse wheel changes the movement speed multiplier.

• Default multiplier: x1.00
• Minimum multiplier: x0.25
• Maximum multiplier: x5.00
• Step per wheel operation: 0.25

When the speed changes, or when the user scrolls at the minimum/maximum limit, the current multiplier is shown in the center of the screen for 1 second.

Configuration

You can customize the base movement speed, fast movement multiplier, mouse sensitivity, initial speed multiplier, and initial height lock mode.

goodnavigate.enable(
    speed=2.0,
    fast_mult=3.0,
    sense=1.0,
    speed_mult=1.0,
    height_lock=True,
    check_window_focus=True,
)

Disable the speed overlay if needed:

goodnavigate.enable(show_speed_overlay=False)

Mouse sensitivity uses a normalized scale. sense=1.0 is the standard mouse sensitivity and maps to the previous internal value 0.1.

Runtime setters:

navigator = goodnavigate.enable()

navigator.set_speed(3.0)
navigator.set_fast_mult(4.0)
navigator.set_sense(1.0)
navigator.set_speed_mult(2.0)
navigator.reset_speed_mult()

Status

Get the current controller state as a dictionary:

navigator = goodnavigate.enable()
status = navigator.get_status()

The dictionary includes values such as enabled, height_lock, speed, fast_mult, sense, speed_mult, and current key bindings.

Window Focus Safety

GoodNavigate stops movement when the Vizard window loses focus. This prevents held movement keys from remaining active after clicking another window.

This behavior is enabled by default:

goodnavigate.enable(check_window_focus=True)

If you need to disable the focus check for a special setup, pass:

goodnavigate.enable(check_window_focus=False)

Pause, Resume, Disable

Pause GoodNavigate controls without returning Vizard mouse handling to its default behavior:

goodnavigate.pause()
goodnavigate.resume()

Disable GoodNavigate controls and return mouse handling to Vizard defaults:

goodnavigate.disable()

You can also call these on the navigator object:

navigator = goodnavigate.enable()
navigator.pause()
navigator.resume()
navigator.disable()

Using A Different View

By default, GoodNavigate controls viz.MainView. You can pass another Vizard view object.

my_view = viz.MainView
goodnavigate.enable(view=my_view)

Repository Layout

pyproject.toml
README.md
src/
  goodnavigate/
    __init__.py
    goodnavigate_overlay_bg.png
  GoodNavigate.py

src/goodnavigate/goodnavigate_overlay_bg.png is packaged with the module and is used for the rounded gray speed overlay background.

The root-level GoodNavigate.py file can still be copied directly into a Vizard project if you want a no-pip workflow, but pip users should use the src/ package.

Requirements

• WorldViz Vizard 8
• Vizard Python environment with viz and vizact
• pip available in the Vizard Python environment
