Houdini交通系统模拟教程 VEX Traffic Simulation in Houdini 18

讲解在Houdini中利用VEX里模拟交通动画，Houdini 18的进阶教程

For the third project in my Houdini course, we had to create a crowd system. The first few lectures covered basic concepts about crowds and how they behave. We also learned techniques like how to implement Reynolds Boids behaviors (separation, alignment, and cohesion) in VEX mainly by using pcopen to gather information from neighboring particles; furthermore, we discussed how to make them react one way or another depending on various parameters, so that was pretty cool. Then we learned more about the built-in Houdini crowds tools that can automatically do all that for you in conjunction with the crowd solver. While the crowd solver and the built-in tools are pretty amazing, I really wanted to experiment and push what I could do with VEX, so I thought a traffic system would be unique. In my mind, the traffic system, being something so mechanical, would give me the opportunity to be in charge of controlling and setting up every necessary attribute like vectors and forces to make the traffic system feasible. At the same time, simulated traffic systems don’t seem to be your typical Houdini project, so I saw it as a double win.
