HDK tools - Houdini development kit tools - these tools are compiled here for various windows builds along with the source code for users to compile themselves for Linux or alternative Windows versions of Houdini. For more information on the HDK and compiling for Houdini see odWiki>>> General installation information for these tools can be found here>>> Note: unfortunately any Linux builds may not be as up to date as the windows ones, so if you can it is best to compile from the source. This is because at present I have to rely on people kindly donating Linux builds.

		RBF Morpher Sop A powerful feature based deformer that uses a radial basis function to calculate the weights of the input geometry relative to a set of feature points. A deformed set of feature points then let you morph the geometry into the target shape.	more>>>
		PGMVC Capture & Deform Sops Positive General Mean Value Coordinate capture deform system. Define a polygonal capture volume and this set of sops will then use it to define a coordinate system that can be used to capture and deform any geometry inside the volume. This method is very close to Harmonic coordinates, the coordinates are always positive making them suitable for character animation. The calculation of the coordinates is more accurate than harmonic.	more>>>
		SBC Capture, Deform & Transfer Sops Spherical barycentric coordinate capture deform system. Define a polygonal capture volume and this set of sops will then use it to define a coordinate system that can be used to capture and deform any geometry inside the volume.	more>>>
		UV Uniform Sop Automatically edit uv coordinates so that the coordinates are uniformly distributed. Attempts to automatically remove pinching and stretching caused by processes like uvpelting.	more>>>
		Poly Crease Sop Procedural version of the polysplit sop.  Poly crease takes a set of curves as a second input that define where the splits should be made.  It also allows for easy patitioning of cut pieces when the curves are closed.	more>>>
		Wrap Capture & Deform Sops Capture and deform one surface with another. A simple deformation system that uses the weighted positions of a set of polys to influence the position of another piece of geometry.	more>>>
		Flex Deformer System Complete asset based Complete asset based solution for linking object animation to geometry to create a deforming surface.
		Partition by Colour Sop Create named groups from primitive colours. Automatically detects existing colours and sorts them, the user can then change the default group names to something more useful.	more>>>
		Point Slide Sop Simple utility sop where the user supplies a set of edges and directions and one parameter lets you slide the root point of each edge parametrically along its parent edge in the direction of the second point defining the edge. Now with added local variable support for edge and point numbers.	more>>>
		Poly Cusp Bevel Sop Procedural version of the polybevel sop.  By specifying a cusp angle the input can be automatically bevelled where the angle between polygon edges is greater than the threshold.	more>>>
		Driven Obj Object utility node allowing for the motion of one node to be `driven` by the animation of another channel.  Key positions are stored in the driven node and indexed into by the specified reference channel, expression or manually keyed animation channel.	more>>>
		Parents Sop Parent points and primitives at sop level to objects at object level. Multiple parents and element types can be defined all in one sop.	more>>>
		Edge Depth Attribute Sop Simple utility sop for adding a falloff attribute to a mesh based on edge count or distance along edges calculated from a source group.  Not a true 100% accurate edge length calculation but useful in situations where an approximation will do.	more>>>
		Tri To Quad Sop An experimental sop for converting triangulated meshes into quad meshes.  A simple algorithm that just removes edges between pairs of triangles falling within certain constraints.  Not a perfect solution but works well in some cases.	more>>>
		Measure Distortion Sop A sop for analysing the distortion introduced by geometry deformation sops.  The attributes it creates can then be used to add procedural smoothing to the geometry.  This is very useful for correcting sharp corners created in character defomation.	more>>>
		UV unwrap LSCM Sop A sop for creating uv texture coordinates. Similar to UV Pelt but using a completely different technique.  This method is used by Blender and RoadKill amongst others. Tutorial movie1	more>>>
		Group Edges Sop Simple utility sop that will convert point groups into an edge group string that can be referenced anywhere you need to use an edge group.  This therefore allows you to effectively create procedural edge groups which are otherwise unsupported.	more>>>
