Hi, below is code to extract four corner points of wall from its dimensions and transform matrix.
center = transform[3]
rightVector = transform[0]
upVector = transform[1]
angle = atan2f(dimensions.y/2, dimensions.x/2)
diagonalDistance = sqrt(dimensions.x/2 * dimensions.x/2 + dimensions.y/2 * dimensions.y/2)
move = CGPoint(x: diagonalDistance * cos(angle), y: diagonalDistance * sin(angle))
topLeftPoint = center.translate(x: rightVector.x * move.x + upVector.x * move.y,
y: rightVector.y * move.x + upVector.y * move.y,
z: rightVector.z * move.x + upVector.z * move.y)
