3D view

Navigate

Drag to orbit, use the wheel to zoom, and pick a camera preset (isometric, top, front…). Hold Space — or turn on the Pan button in the toolbar — to drag the camera sideways instead of orbiting. Perspective and orthographic modes are available. A day/night button swings the light from sun to moon. Your last camera preset, projection and sun position are remembered between sessions.

Walkthrough

Enter first-person mode to walk through the rooms at eye level. Doors can open; free walls block the path like room walls. Keyboard shortcuts are listed under Help (or `?`). On a headset, the zen controls follow you into the scene as a small panel at your left wrist, pointed at with the other controller.

Render styles

Choose a look for the model: sketch, clay, blueprint, cute — where the volumes themselves get rounded edges — and Realistic, a physically based style lit by a studio environment. Styles change materials and lighting; a few also soften edges. The style is saved with your preferences.

Roofs and levels

Multi-level plans stack in 3D. Roofs can be shown or hidden when the level has a roof definition. The first time you orbit a house with its roof on, a short tip offers to hide it (`T`) so the rooms show from outside. Levels can be reordered by dragging their chip in the floor list — stairs and lifts are reconciled, and the whole move is one undo. House vs apartment changes the ground: a plot with margins, or a concrete slab that follows the footprint.

What to show

The visibility menu decides what the model shows: roofs, a section cut, door leaves, and a furniture-free view that strips all furniture from both 2D and 3D without deleting anything (`H`). Press `I` for a load readout — frames per second, draw calls, triangles, geometries and textures, plus the current style — handy for comparing what each render style costs.

Zen mode

Zen opens your model alone, full screen, in its own tab. It stays in step with the tab you are working in: edit on one screen, contemplate on the other. Nothing is lost when you close it — it is a way of looking, not a separate document.

A column of controls sits at the left edge and fades until you reach for it:

• Season — spring, summer, autumn or winter, with falling leaves or snow
• Day or night, with ambient sound you can mute
• The surrounding neighbourhood, which you can hide to keep the house alone — and a cat you can call over
• A slow rotation you can stop, and a switch between isometric and perspective
• A headset button to step inside the model, or place it in your room in augmented reality

Music

Three ambient tracks come with Planaira: Blueprint Garden, Blueprint Daydream and Blueprint Breeze. Click the music note in the top bar to open the panel: the track list, the one playing named above it, and the volume at the bottom. Closing the panel does not stop the sound.

One track follows on from the next, and the volume is remembered between sessions — the same level in the editor and in zen mode, where the player shrinks to a single play/pause button and shows the track name while it plays.
