Houdini 17.5 released
Update Houdini 17.5 is now available. You can find more information about all the new features on the updated Houdini page on the SideFX website.
The standout feature of this version is the introduction of the Procedural Dependency Graph (PDG) API. According to SideFX, this new technology is designed to “describe complex dependencies visually with nodes; transform that dependency description into a set of actionable, schedulable tasks; and distribute those tasks with the help of a scheduler and compute them in parallel”.
The PDG API is expressed in Houdini as a new operating context called Task Operators (TOPS), but also via a standalone application called PilotPDG.
Due to the scale of this new feature, it consumed most of SideFX’s development resources for this release. However there are still several other useful features, including alpha cutouts for heightfields; GPU accelerated volumes in the viewport; a principled shader with visual parity between apps, renderers and viewports; material based destruction with interactive RDB constraints; per-point friction, fibre constraints, and grooming tools in Vellum; sliced and clustered mode for distributed whitewater; distributed narrow-band sims; surface analysis in Measure SOP 2.0; and the ability to select polygons by pattern and face normal.
