Re: PointLocators in ICE

locators are more or less that, barycentric coordinates coupled with a facet index kinda thing. Why they are not exposed atomically isn't 100% clear. It might be some eval issues with those atoms if they were to be exposed, just lack of foresight in the implementation somewhere back then, simply so

PointLocators in ICE

Figured I'd start a new thread. This has been arousing my curiosity for a while and I need your wisdom :-) In Houdini I build locations by providing a polygon index and what is called a "uv parametric location". The term uv is misleading here. All it is, is a coordinate on each polygon plane. Sof

Re: getting subsurface index

I understand the problem, I had to work with combined curves and found difficult (impossible?) to access subcurves. Looks like an area of ICE that could be improved a lot by exposing the right attribute. Good luck and keep us posted with your discoveries. On Tue, Jun 11, 2013 at 5:10 PM, Matt Lin

Re: placing random sized shapes in ICE

These are bits of textured geometryunfortunately rather specific shaped bits of geometry, though simple rectangular-ish boxes. I thought it might be tough :) I might try emitting in em flock to use the particle avoidance, and use their initial positions on another cloud to emit the instance

Re: placing random sized shapes in ICE

Finding the distance across a parametric surface is a miminization problem (there is no direct solution to just go from this point give me a point at this distance along this axis, you have to integrate your way to it), and setting rectangles flush within boundaries is a packing problem, which is a

placing random sized shapes in ICE

hello all, i need to place particle instances.on a surface. each of 5 instances in a group are rectangular, but of different lengths. like boards in a floor. there can be no gaps. i can do this with similarly sized rectangles but fail in arranging these randomly and sensing their sizes/shap

RE: getting subsurface index

BTW - you get the UVW coordinates from the polygon node index array returned from the PointLocator. The UVW coordinates are stored in a ClusterProperty of type 'uvspace'. You need to use the Polygon Node Indices returned from the PointLocator to look them up in the uvspace property. Matt

RE: getting subsurface index

You only need that method when comparing PointLocators across multiple subsurfaces to make decisions. In my case I only need the nearest location on the surface mesh. NURBSSurfaceMesh.GetClosestSurfacePosition2() returns the subsurface index as part of the PointLocator object. In the case of

Looks like this methodwould be useful to you if it was implemented in ICE. It'd be perfect with t

Hi, I thought a few people in the list might be interested in a little bit about how I use Softimage as the core of the 3d asset pipeline I have created for my game engine. A mini post mortem, if you will. I'm always promoting Softimage in the various social spaces I hang out in, giving advice

Voronoi, but only on surface, no thickness

Hi people, i was wondering if there is a simple way to fracture (voronoi or else) an object but without any thickness. For example when you shatter an object with the old Kratos, it gives you big fat volumic chunks . What if I want only the surface ? I'd like to prepare a pealing effect. Hop

No anti aliasing while navigating?

Hi list, I turned on the High Quality viewport in SI 2014 in my scene to get anti-aliasing. But the anti-aliasing only works when the camera is stationary. As soon as start navigating, I get the old pixelated mess. I want it to be enabled all the time, not just when I stop navigating. What gives?
