Since we use an iterative approach, Architectural specifications can be revised on a design-build basis (like most real-world projects). The client is not bound by a final submission. Production begins with the massing of 3d modeling via wireframes. During this step, black and white 3d renderings (ambient occlusion) are produced and submitted to the client as required to reinforce project direction. This step is extremely useful because the client sees preliminary massing in black and white without being persuaded or distracted by textures and lighting. Here is where the ongoing feedback loop keeps the project moving forward.Although, some clients are satisfied with ambient occlusion as final, most prefer the full experience of photo-realistic 3d rendering.
