How to visualize the data?

[danteppc]

Hey!

I'm writing a similar project, I collect acceleration and gravity data, but I have no idea on how to simulate the actual movement on a 3D space i.e. SceneKit

Any ideas?

Hey @danteppc did you ever manage to find a solution to this?

Great that you did. Do you have any screenshots of what it ended up looking like? Thanks, Jeremy

Yeah I did something like this: ` for i in 0..<xs.count { //let index: Double = Double(i + 1) agg_t += 0.01 // speed = lastSpeed + (currentAcceleration - lastAcceleration)/2 * INTERVAL let accel = shot.accelerationsOrdered[i] var speed = Velocity() var distance = Distance() speed.x = lastSpeed.x + lastAccel.x + (accel.x - lastAccel.x)/2.0 speed.y = lastSpeed.y + lastAccel.y + (accel.y - lastAccel.y)/2.0 speed.z = lastSpeed.z + lastAccel.z + (accel.z - lastAccel.z)/2.0 // location = lastLocation + (currentSpeed - lastSpeed)/2 * INTERVAL distance.x = lastDistance.x + lastSpeed.x + (speed.x - lastSpeed.x)/2.0 distance.y = lastDistance.y + lastSpeed.y + (speed.y - lastSpeed.y)/2.0 distance.z = lastDistance.z + lastSpeed.z + (speed.z - lastSpeed.z)/2.0 lastAccel = accel; lastSpeed = speed; lastDistance = distance; totalDistanceTraveled.x += distance.x totalDistanceTraveled.y += distance.y totalDistanceTraveled.z += distance.z let node = SCNNode(geometry: SCNSphere(radius: 0.4)) node.geometry?.firstMaterial?.diffuse.contents = UIColor.systemGray node.position = SCNVector3(distance.x/5, distance.y/5, distance.z/5) scene.rootNode.addChildNode(node) let line = SCNNode.lineNode(from: simd_float3(0,0,0), to: simd_float3(Float(speed.x/5),Float(speed.y/5),Float(speed.z/5)), radius: 0.3) line.position = SCNVector3(lastDistance.x/5, lastDistance.y/5, lastDistance.z/5) scene.rootNode.addChildNode(line) }` — You are receiving this because you commented.
