Click the green flag, then click the stage to use the keyboard. CONTROLS W / S: walk forward / backward A / D: move sideways Left / right arrows: turn Up / down arrows: also walk forward / backward Q / E: look up / down. Release to keep that view. Space: jump R: return to the starting position and reset your view THINGS TO TRY Walk underneath the bridge, then find the stairs along the left wall and climb onto its deck. Stairs climb automatically as you walk. Look for the spinning green crystal. Move behind the low wall and watch it cover part of the crystal. This is an exploration and rendering demo. There is no score or finish line.
STRATA combines a 120-column raycaster for the room with projected polygon faces for the spinning crystal. The bridge has a walkable top and an open passage underneath. Wall shading and distance fading help show depth. When the camera is still, the renderer reuses the room's projected surfaces while the crystal keeps rotating. The number in the top-right corner is the current FPS; performance varies by device and view. Looking up and down uses a limited horizon shift to simulate tilt. It cannot look straight up or straight down. The scene currently supports the ground plus one solid height interval per map cell. Created with help from VibeScratch. The interface artwork was drawn for this project.
