Flythrough is a display mode intended to give you the impression you are inside the model looking around.
When setting up a flythrough mode, typically the screen is split with one viewport to show the camera position and one for flying through.
To flythrough your design
Click the Show Camera Options button in the Display tab
- Camera settings are per scene, not per window
- Click the button to activate Flythrough in Viewport 1
- Camera type will change to Perspective
- You can choose a camera type
- Orthographic - Parallel lens
- Perspective - Divergent lens
- In the Flythrough viewport, spin and zoom to fly through the model
- (Optional) Open a second viewport to control the camera position or trajectory.
To position the camera
- Click the Identify Viewport button to show viewport numbers
- In the Options , click the Show Camera button
- Choose a viewport for the camera in the Show Camera dialog box
- The camera position is shown in the selected viewport (default is 0) and your model as seen from the camera position is shown in the active viewport (default is 1)
- You can change the activate viewport by clicking in them or selecting them from the Active Viewport dropdown in the
- (Optional) Adjust the Width or Height of the camera film
- This adjusts the zoom level in the camera viewport
- When you click in either the Width or the Height inputs, the corresponding film edges highlight in the scene
- You can also hold the ALT key while zooming IN/OUT in the Flythrough window to increase/decrcease the width and height
- (Optional) In the camera viewport, position the camera using the tool
To move the camera with the Move tool
- Turn the Camera ON in a viewport
- Turn Flythrough ON in another viewport
- If Flythrough is OFF, you cannot select the camera to move it
- Enter the tool
- Select a part of the camera to move. Referring to the image below, you can select either the Sight (light blue line), End (blue dot), or Camera End (green dot).
- Use the Handle to position the camera
- Moving the green dot moves the Camera End. The End remains fixed as if you are walking around the End while keeping your eyes pointed at the End.
- The Handle reorients after the move to show that it remained pointed at the End during the drag.
- Moving the blue dot moves the End while maintaining the Camera End position. This has the effect of moving the object in space while keeping the Camera fixed (like moving the object while keeping your eyes pointed at the camera).
- The Handle reorients after the move to show that it remained pointed at the camera during the drag.
- Moving the Sight moves the Camera as a whole
- Dragging linear directions maintains the camera orientation during the move
- Dragging rotational directions pivots the camera about the sight line midpoint
- Use the Up To tool guide to attach the camera to selected geometry
- Attaching the Camera End and then moving the End linearly rotates the camera while it is fixed to the selected geometry
- Attaching the End and then moving the Camera End linearly is like walking around while keeping the camera fixed on the target
To move the camera along a predefined tragectory
With the Camera attached to a curve, you can use the Along tool guide to move the camera along a predetermined path.
- Select the Sight to
- Click the Up To tool guide
- Select the curve endpoint
- Orient the camera to establish the viewing direction
- Click the Along tool guide
- Select the curve
- Start dragging along the curve
- The camera follows the curve and the view direction moves accordingly
- Continue dragging until the end of the curve
