Three ways to place the model in real space
For the model to match the real place, E-SPACE must know where the model is relative to the space the viewer sees. There are three ways to tell it, and each one is good for something different.
1. With QR markers: the most accurate
In Rhino you mark with EsMarker the points where the QR codes will go, print them with EsMarkerPrint and stick them on those same points in the real place. When the viewer sees a QR, it knows that point of reality.
- With one QR the position is fixed, but the rotation is not corrected.
- With two or more the model is oriented and always stays at 1:1 scale.
- With three or more the local error goes down, because the three closest to where you are are used.
When it fits: setting out on site, parametric walls, any case where you ask for centimeters. For ±1 to 2 cm, one QR every 1.5 to 2 meters on the wall itself, well placed with a tape measure or laser. And with EsPrecision you can see in Rhino, before going, where it will be accurate.
2. By hand: without scanning anything
With the controller tip or your index finger you tap the real corner of each marker, in the order the app asks. Holding a point pressed corrects it and, when finished, the model stays anchored and fixed.
When it fits: when QR codes do not read well (low light, reflections, distance) or you did not print them, but you still have the reference points. It is a good safety net. Accuracy depends on your hand: about 1 to 2 cm with a finger or the ray.
3. On the floor or a table: the fastest
No markers. The viewer detects the horizontal surfaces of your room and you rest the model where you point. For a table, you measure its height by resting the controller or your finger on it. You can rotate the model in 15° steps and choose any scale, from 1:1 to 1:100.
When it fits: scale models, classes and presentations. It is ideal for showing a project at 1:10 on a table. It is not the way to set out a wall.
A note on accuracy
E-SPACE's maps and indicators are an accuracy model, not a measurement. It is best to check against a measured reference, and critical measurements always with the instruments of your profession. More in How it works and in the user guide.
