  1. Invert Matrix

    Hello! There is the following code and a very strange result which returns the function of invert. How does the invert function actually work for zero determinant matrices? matrix3 matA = { {1,2,3}, {4,5,6}, {7,8,9} }; // Find the determinant of the matrix // If the determinant value is zero, then an inverted matrix cannot be found for such a matrix. int det = determinant(matA); // det == 0 matrix3 matB = invert(matA); // { {-0.75, 0.5, 0.25}, {-0.5, 0, -0.5}, {0.5833, 0.5, -0.083} }
  2. Export Import alembic camera with Python

    To import a camera through alembic, a good solution is not to use the Build Hierarchy every time, but read the parameters directly from it using the module. >>> import _alembic_hom_extensions as abc http://www.sidefx.com/docs/houdini/hom/abc_extensions.html From it you can pull out all the transformations and some data on the camera. For export, it is better to have a HDA in which you could indicate the path to the camera where all its parameters would be read, after that the camera would be baked and then exported to Alembic.
  3. Drag&Drop Contents

    I think that the $HOUDINI_SCRIPT_PATH variable may simply not look in the folder with these scripts, maybe you didn’t have a typical Houdini installation. And what was the exact error there? I'll fix the script.
  4. sinus loop/cycle

    Try using this formula, sin( ($ FF + ($ PI / 2)) * 2).

  6. Drag&Drop Contents

    The script implements the ability to drag files of geometry, caches, textures, images right into the viewport. This project was open-source, so I spread it for everyone. Can someone come in handy. Thank you for watching! Projects: https://github.com/alexwheezy/python/tree/master/houdini/drag_drop_files
  7. Houdini 17 Wishlist

    If the deal with settings that offer, then we can achieve the color scheme in the Pro version. The only thing that I could not do it properly edging around the node, it is not enough.
  8. Hello everyone! There is such a little problem here, it would be desirable in the context of ROP link multiple nodes to be considered locally and some tasks should be sent to the farm. What I want in an ideal? To the end of all nodes of the tree could click on the Render button and tasks of the beginning of the considered local, and some went to the farm. Is it possible at all to do? Thank you in advance!

    Thank you, zarti. I hope at least someone interested and if it helps then I'll be happy

    Well, we have to wait a little bit)
  11. Character Setup

    Hi everyone! This is my new rigging. This time I chose a car for their test. I tried to combine the two types of behavior in a car, in which one type has the approximate form of a reality, and the other is a caricature. At the moment, this rigging is in the form in which you see now, maybe in the future I will modify it yet. If anyone is interested, I share otl library. As usual criticism, suggestions are welcome!

    I want to have the development of character animation, and that now is not very comfortable with that.; OOP in VEX?

    Thank you, angelia! There is still work to do. wurmdrin1111, I love rigging in Houdini and yet not to understand why it is not used on large projects, and why so little time to improve it spends SideFX. Rigging general theme is not easy, but Houdini sometimes not obvious. I made this rig using the knowledge and experience gained in Maya, but quite a bit. Basically it was a competition between me and my brains Approaches rigging in Maya and Houdini are quite different, so the standard things that worked in the Maya Houdini had to repeat the behavior of some operations using math expressions and simple logic. This rigging with the standard requirements before animators riggers, I is not touched upon the facial animation, muscle strain, dynamic simulation, and much more, so that more experiments will be enough. With regard to good tutorials on rigging in Houdini, I think the best fit course of lessons 3DBuzz, but unfortunately in our country they do not deliver, but in a different way as they did not seem to buy so I had to learn most from our mistakes. See lessons from other authors on the Maya, XSI they will greatly help you and advise in what direction to take to achieve the desired result. Hopefully, something made ​​clear
