Christian S Posted May 6, 2015 Share Posted May 6, 2015 Hi, On a grid, I used a VOPSOP with a point cloud lookup to find the closes point around my current point that has a specific attribute. And then I can measure the distance between them and compute other stuff. But, this system is slow (We have a big pipeline with many different things, this is just part of it). We decided to swtich to COP since we can treat the grid as an image. 1 point == 1 pixel. What I want to know, can I use the point cloud nodes in a VOPCOP2FILTER inside a COP2NET? Pixel position is the same as point position right? But how do I specify the Point Cloud Texture (file) to be the COP image? Is it posible at all to use Point Cloud nodes in COP context? Thx for your input. C Quote Link to comment Share on other sites More sharing options...
anim Posted May 7, 2015 Share Posted May 7, 2015 you can use point cloud nodes in cop context, however still only for sampling points from file or sop geo I guess for querying pixels around certain pixel position you will need to write custom functions, luckily it's really predictable, since pixels are always in a grid and not sparse as point clouds Quote Link to comment Share on other sites More sharing options...
Krion Posted August 23, 2021 Share Posted August 23, 2021 I wonder if such a feature, function or script has been published somewhere. Now 6 years later. If anyone knows something, I'd appreciate if you let me know. :-) Quote Link to comment Share on other sites More sharing options...
