Movement is associated with line and closely related to balance.
The trunk-line is the core of the movement while root lines, branch lines and branch profiles also contribute.The stance of the tree has a considerable impact on the over all movement.
The tree below is planted on a rock. The angle that the rock makes with the ground and the line of the roots enhance the movement of the trunk. However the tree does not quite look natural.
Whether the movement is dynamic with strong angular changes or a gentle unwinding of curves, affects the mood of the tree and the image it conveys to the viewer. To make an integrated design the branch placement, primary branch lines and profiles created from secondary and tertiary branches should support the mood.
It should be clear that movement is a product of line and thrust.Here the trunk thrusts outwards from the rock, but then the energy of the curve is dissipated by the backward flow evident below.
However the thrust of the base is paralleled in the branch at A. This suggests an alternative to advance and integrate the design.
The tree on the left is a combination of angles and curves. The primary branches arise from the outside of curves, thus enhancing and continuing the movement and the branch profiles angle to echo the movements in subtle ways.The overall mood is one of controlled dynamism achieved in large measure through a balance of elements and masses around the central core of the trunk.
Below we see a possible line with the branch at A forming the new apex and the profile of the apical branch echoing the movement.The lower branch becomes a balancing factor to stabilise the design.
One should always be on the look out for repeating lines as they add a wholeness and connectivity to the image; subtle nuances can be developed to avoid any dullness.
