Does FW Pres. Need Sunnies?

The big window behind the pulpit faces southeast. A few Sundays a year the sun lines up with it and shines straight into somebody's eyes during the sermon. This is the sanctuary, rebuilt from photos, so you can see exactly whose.

This browser can't draw the 3D sanctuary, but every forecast below still works.

    The view from the pulpit

    How it works

    The sun is far enough away that its rays arrive parallel. For any seat, draw a line from your eyes toward the sun. If it passes through the stained glass, you're squinting.

    The sun's position comes from NOAA's solar equations for 6251 Oakmont Trail, with daylight saving handled. That's why the glare jumps across the center aisle when the clocks fall back in November.

    The room was rebuilt from seven phone photos, aerial imagery and the church's drone video. Rendered from the same spots, the model lines up with the photos, and it puts the early-morning colored light on the same right-center pews where it shows up in them. The window faces about 135°. The glass is roughly 2.9 m wide and runs from 2.6 m to 14.6 m off the floor.

    Model settings

    Calibrate from a sighting. Pick the seat where the sun hit you, set the date and time below, then press Fit. The window's direction is adjusted so the sun sits dead center for that seat.
