1970s Carpet

1970s Carpet

This material is an example of how quickly you can get from simple to complex in the Poser material room. This pattern only requires four nodes, two to produce the pattern and two to control the results. The result reminds me of the patterned carpets common during the 1970s.


Fig 1: Our Target

We start with a simple Wave2d node. In this example I have set frequency to 8 and phase to 2. These values work in tandem - the higher they are the more complex our final material becomes.


Fig 2: Our Starting Point

We are now going to modify the output of our Wave2d node using a weave node. The only significant change I have made to the weave node is to change the U_Scale and V_Scale settings to 5. This produces a weave with ten strands across and ten strands down. When the output of this weave is plugged into the frequency channel of the Wave2d, the neat circles of the wave are totally distorted, producing the pattern seen in Figure 3.


Fig 3: Sudden Complexity

Finally, we need to modify the output of the Wave2D node so that we can use it to drive a ColorRamp. Wave2d outputs a number between -1 and 1. We could use that directly in the ColorRamp, but we would loose half of the detail present in the wave. Instead we are going to modify the output of the wave to bring it into the range 0 to 1. To do this, we create an Add maths node. Both Value_1 and Value_2 are set to 0.5. The output of the Wave2d node can then be plugged into either node. This first reduces the range of values produced by the Wave2d node to -0.5 to 0.5, then adds 0.5 to the result, giving us our 0 to 1. Finally, we plug the output of the Add node into the Input channel of the ColorRamp node, and select our colours.

Modifying the Material

The U_scale and V_scale values of the weave controls the number of squares in the final patterns. Bias and Gain control the details of the pattern.

On the Wave2d node the phase and frequency settings control the level of detail within the squares - the higher the settings the more detail.
