“The Pergola” is a project showcasing a mailbox landscape scene modeled in Houdini, aiming to create a charming, inviting, and richly detailed environment using entirely procedural generation methods.

My inspiration came from various mailbox landscape photos from Pinterest which give a cozy and welcoming aesthetic.

I was particularly interested in creating the specific, delicate forms of Wisteria flowers after learning the methods to create lavender bushes.

The foundation of this scene is a sophisticated set of point scattering and attribute wrangling systems. I used scatter techniques for the grass and for the lavender bushes, I mastered the Copy to Points technique, using VEX attributes to control pScale and N (normal) to randomize the size and rotation of the bushes, making the lavender look realistic. I’ve used procedural modeling techniques by utilizing poly extrude, poly bevel, and group nodes to create the mailbox and pathway lights, and fences.

My biggest technical challenge was creating the wisteria vine's realistic wrapping behavior. The solution was the Find Shortest Path SOP. This node was crucial because it calculates the minimal distance path across the pergola's geometry, essentially telling the vine where to grow and wrap naturally. Since the node outputs disconnected paths, I had to develop custom logic to merge the curves sequentially to form a single, continuous vine. This complex attribute and curve control, followed by copying the flower geometry onto the path, was a huge but rewarding hurdle that took a full week to refine

In terms of custom textures, I used Houdini’s COPs (Copernicus) to create a wood texture for the fences and the arch the wisteria creeps on. I’ve utilized noise, color ramp, and transform nodes to achieve the realistic texture.
