Batter’s Eye

See the pitch from the hitter’s perspective

Overview

Batter’s Eye places the camera at the batter’s eye position in the batter’s box. You see the pitch coming toward you — just as the hitter does.

Activating Batter’s Eye

Click one of two buttons in the toolbar:

Button Description
Batter’s Eye View from the batter’s box matching the current batter’s handedness
Opposite Eye View from the opposite batter’s box

The camera moves to the batter’s eye position. The 3D batter figure hides so it doesn’t block your view.

Camera Position

The eye position is determined by:

  • X (lateral): ±0.65 m from center, based on batter handedness (R = right box, L = left box)
  • Y (depth): 0.216 m behind home plate
  • Z (height): When Statcast data is available, the height is set to sz_top + 0.3 m (strike zone top + 30 cm). Without Statcast data, it defaults to 1.45 m (batter model head height).

Controls in First-Person Mode

Looking Around

  • Mouse drag — rotate your view (turn your head)
  • Scroll wheel — adjust field of view (FOV)

Moving Position

You can fine-tune the eye position with keyboard controls:

Key Direction Amount
W Forward (toward pitcher) 1 cm
S Backward (toward catcher) 1 cm
A Left (toward 1st base) 1 cm
D Right (toward 3rd base) 1 cm
E Up 1 cm
Q Down 1 cm

The offset from the original position is displayed in the top-left overlay:

Eye offset: X +3cm  Y -1cm  Z +2cm

Ball Tracking

Mode Description
Track: Ball (default) Camera automatically follows the ball during playback
Track: Pitcher Camera stays fixed, looking toward the mound

Click the toggle button in the overlay to switch.

Best Uses

Tunnel evaluation

Enable overlay, simulate a fastball and a changeup, then switch to Batter’s Eye. Play the animation and watch both balls approach. If you can’t tell them apart until the last moment, the tunnel is effective.

Pitch recognition training

Watch a pitch in Batter’s Eye mode at slow speed (use frame stepping with ← → keys). Notice when you can first see the difference between a fastball and a slider.

Video export

Record the Batter’s Eye view as MP4 with the REC Slow button. Share the video to show what the batter sees.

TipCombine with Spin Axis

Enable the Spin Axis button while in Batter’s Eye. You’ll see the spin axis arrow on the approaching ball — this is the visual cue that elite hitters use to identify pitch type.
