  1. Congratulations, SideFX -- and a priceless still frame! Best of luck for the future and keep innovating!
  2. Benchmarking Ray Tracing for Realistic Light Transport Algorithms For those interested in low-level raytracing performance, a comparison of acceleration structures. http://bwfirt.sourceforge.net/

    Oh you want to do this directly in the viewport? I was hoping Render COP pointing to a OpenGL ROP would let you grab the viewport, or failing that some kind of python function to yank the GeometryViewport and then do your thresholding and use that to scatter colored points on the viewing plane - your sprites. Sadly the very first step doesn't support opengl rendering directly into COPs, and I can't find an appropriate python function. What speeds are you looking at wanting? Realtime? If so you might be in HDK Viewport Render Hook territory.

    Isn't that cool?!!
  5. Fly mode

    Looks interesting; I'll give it a try. Thanks for sharing, Jason

    Or get to know the Point Replicate SOP!
  8. Convert to RAT Shelf Tool

    Hi, Good luck with your toolset! I've written a RAT converters a few times over the years, and I'll make just one suggestion -- using the multiprocessing module and perform 5-10 conversions simultaneously in a multiprocessing pool. Super easy to add and improves the turnaround time immensely.

    I would imagine this is not very applicable to VEX, really because it's executed in SIMD fashion -- ie. Single Instruction Multiple Data -- which basically means that data isn't laid out in single data units as it appears in the code, but instead are each large uniform arrays in memory, loaded with data from the entities it's processing (eg. points, prims, etc). These arrays are dense and chewed through in a processor-pipeline-friendly fashion. If you look at the runVex() HOM command you can see how you need to provide arrays of data.
  10. Houdini 16.5 Sneak Peek

    This is definitely a masterful release - bringing lots of great new functionality. Thanks, SideFX!
  11. Graphing bitcoin in Houdini with python

    Interesting, I didn't know that. Perhaps SideFX would have some insight if you wanted to solve this puzzle. FWIW, we have implemented our own URI handlers pointed at our asset system using that class. It can be very intuitive if done right.
  12. houdini theme

    It looks really good -- does it exist on Orbolt, and for H16?
  13. fmx 2017 // Houdini od-lunch // Wed May 3

    Wish I could join you all! Have fun!
  14. Games-related interesting links

    Welcome to the odforce Games forum! Please post material related to game development using Houdini and Houdini Engine in here.
  15. Graphing bitcoin in Houdini with python

    Note sure if totally related, but did you know that you can use http:// and ftp:// URI's directly in file fields in Houdini? For example, you can refer to an image fetched by an http request directly in COPs, textures, backgrounds or wherever you encounter image paths. PS. You can add your own -- see the FS_ReaderHelper/etc docs

    Aw I love trip hop from the naughties! And yes; love Alexey's austere work

  18. Mantra vs Redshift

    I would say some huge studios are spinning up some departments upon some scope of work on Redshift. Most huge studios have thousands of headless blades in their render farm and far fewer with matching GPU resources. Software rendering will be around for years to come. Switching renderers is not trivial for for large, established pipelines for very many reasons. That said, Redshift does a great job. It's not nearly as flexible, broad and pipelineable (from Houdini) as Mantra, but produces good images, fast.
  19. Learning DOPS, motors, constraints etc

    These are seriously very cool experiments to watch. Thanks for these!
  20. Random link of interest

    Interesting little study on 'wrinkles' vs 'waves' over medium of varying viscosity, from a geeky blog with one of the best names! http://fuckyeahfluiddynamics.tumblr.com/post/157782397936/if-youve-ever-sat-out-on-a-lake-and-just-watched
  21. Houdini 17 Wishlist

    Houdini 16.0.535 Show VDB Voxel Size even in non-verbose mode to match H15.5 info. Well done!
  22. Houdini 17 Wishlist

    ... Except for the kitchen sink nodes: Facet and Divide. The functions in these nodes are so undiscoverable, IMHO. I would still live a true Tesselate function, and a Dice function (based on Mantra's dicing, adhering to the Measurer strategy).
  23. Houdini 17 Wishlist

    This sounds like an oversight (bug)
  24. Mesh Blend

    That's pretty impressive - the results look pretty good. Perhaps you could consider uploading that to Orbolt?
