Touchdesigner visual part 2 – Thresh node

Based on B2BK (20223) tutorial video, I learned about the knowledge of the thresh node. Through the thresh node, we can process a portion of the particles. I connected it to a constant node and adjusted the green and blue values in the constant node’s RGB to 0. This allows us to manipulate the particles that belong to the red portion. As shown in Figures 1 and 2 and 3, I attempted to cut this staircase into two parts.

Figure 3

However, when I tried to manipulate parts of the image other than the red section, such as the green or blue sections, the changes were not noticeable. Therefore, we abandoned the use of this node.
