Houdini Find Shortest Path

Use find shortest path to generate paths to the center point of the grid Create a u-coord for each path create a point for each path animate it down the path delaying the timing per point either randomly or by a ramp or by distance. However Ben managed to come up with a neat compact setup that relys purely on Houdinis built in tools to achieve effects of similar complexity without the need for any coding.

This node can be used to measure the distance along a surface which is useful when masking operations based on distance.

Houdini find shortest path. You can change this using the Forward direction parameter on the Capture and Align tab. This node only bends the parts of the geometry inside a capture region. The reason this setup creates a bunch of overlapping polylines is that the find shortest path node is setup to connect a few starting points to a big number of end points.

It is built out of these 4 nodes. Lets apply the Remesh the 3d model will be remeshed into triangular polygons after that will create a Group Create Group by Range selected a point and create a start and an endpoint group. Using shortest path to draw curves from start to these 3 endpoints.

Since the HF Layers have transferred over to the primitives as attributes I use the water attribute to isolate and promote the water primitives into a group so we can avoid running paths through them. This node finds the shortest paths through edges of the input surface geometry between all pairs of start and end points creating polygon curves along those paths. There are many options for specifying path costs other than just the length of the path for example costs for visiting certain points.

Houdini Beginner Tutorial Improved Shortest Path Growth Original tech and workflow from Ben Watts and Toadstorm. Parts of the model outside the capture region still move with the rest of the model but do not. Measures the distance of the shortest path along the geometrys edges or surfaces from each start point.

Thus the paths needed to form all the connections end up using parts of the same paths to get to the individual end points similar in a highway network where the big cross country highways are the biggest and most frequented roads. By default the node assumes the geometry is modeled along the Z axis with the front in the positive Z direction this is the standard default for Houdini tools. This node finds the shortest paths through edges of the input surface geometry between all pairs of start and end points creating polygon curves along those paths.

In video 2 well learn how to Find Shortest Path and VDB modeling in Houdini after this process well see how to create a Path Growth effect on the 3d mesh in Houdini. This one will be a bit more abstract yet still very useful procedural generations of new geometry based on other geometryThe free Mantra rendering works. Once weve grouped the start and end points on the landscape we can then start generating the paths.

There are many options for specifying path costs other than just the length of the path for example costs for visiting certain points. The next step is making the root growth path and animate it. This node is the key to making a root mesh it finds the shortest paths through edges of the geometry between all pairs of start and end points we chose earlier creating polygon curves along those paths.

Followed Entagma shortest path tutorial by Ben Watts This question was asked before In fact the resulting growing curves have point number changing every frame and I cant manage to sort the points so that their number dont change anymore.
