How to move the viewpoint freely?

Navigation Mode

The Navigation mode in the upper right corner is divided into three types: Orbit, Fly and Walk.

Orbit

The viewpoint moves around the object in the center of the screen, using a combination of the mouse wheel, the right mouse button, and the Shift key.

• In the Orbit mode, when you press the right mouse button or the scroll wheel to click on the model, the intersection point of the mouse and the model will be regarded as the orbit point, and the object will rotate around this point.

• In the Orbit mode, when you press the right mouse button or the scroll wheel to click on the background, the gizmo of the selected object or the object closest to the center of the screen in the current viewport will be regarded as the orbit point.

• Orbit view supports visual icon to help users identify the center point of the current rotation, improving operational feedback and sense of control.

Fly

Use the right mouse button with the WASD on the keyboard to Use the center of the screen as a moving target.

Walk

Walk and view the scene in the first person, right mouse button with WASD on the keyboard to move around.

• After switching to Walk Mode by clicking on the upper right corner of the interface, the viewpoint will drop down to the object below according to the set height.

• When using WASD to walk, always keep the camera height to move, such as encountering a wall will cause collision and can not pass through.

Parameter Adjustment

1. Movement speed:

• Orbit Mode

In 'Orbit'Mode ,The speed is not adjustable.

The movement speed is related to the distance of the lens from the objects in the scene, moving slower when the distance is close and faster when the distance is farther away.

• Fly and Walk Mode

  • In 'Fly' and 'Walk' modes, when pressing the Shift key, the speed will become 4 times faster than the original speed. Press the Space key to decelerate the speed. Press the Shift+Space keys to accelerate by 2 times. When the speed is set at 1, pressing the Space key will lower the speed to 0.2 for tweaks.

  • You can press the right mouse button and scroll the wheel in Fly Mode and Walk Mode to modify the movement speed, scrolling the wheel fast to change the speed quickly, scrolling slow to fine-tune the speed.

2. Eye level:

Adjust the vertical height of the actual viewpoint of the lens from the horizontal plane of the scene origin coordinates, the range of the slider value of the lens height in the Walk mode is 0.8m-2.5m, and it does not support manually inputting a larger value.

3. Altitude

Adjust the vertical height of the actual point of view of the lens from the horizontal plane of the scene origin coordinates, the range of the slider value of the flight height in the Fly mode is 0m-50m, and it supports manually inputting a larger value.

4. Roll

Control the rotation angle of the camera in the horizontal direction.

5. Mouse Speed

Adjust freely the speed at which the camera rotates around the object in Orbit mode, and the speed at which the camera turns its head up, down, left, right, and center in both Fly & Walk modes.

FAQs

Q: Why does moving the viewpoint with WASD not work?

A: WASD shortcuts only work when the movement mode is fly and walk.

• In orbit mode, you need to use the mouse and scroll wheel to adjust.

Q: Why can't I use walk mode?

A: If the landing site is not captured in the current view, it will automatically switch from walk mode to fly mode or fail to switch to walk mode and display the ↓ prompt.
