  1. Hello there!! I have this sphere, and I want its extrusions to have a gradient in its colors. The pick to be the more intense and the base to have the same color with the base of the sphere. How can i do that? Please help!! cheers!
  2. color gradient in extrusions

    That is great! Thank you so much!
  3. Hello there!! I want to select all the primitives that have a specific attribute - @P = 0 - and assign a specific color to them. How can I do this in VEX or with nodes? cheers!!

  5. list of vertices

    thank you so much!! It works great!
  6. list of vertices

    Hello there!! I want to do something really easy I guess, to create a list with all the vertices for each primitive. - I am working with a polyedron- How can I do that in VEX? cheers
  7. list of vertices

    I want to store them as an attribute, for each primitive of the polygon (triangle) its three vertices; Could the expression be something like: int prim_vertices[]; @prim_vertices = primvertices(0, @primnum); The problem is I don't know how to use them correctly. Please can you tell me how I could write the full expression?
  8. Hello peeps! I want to do something really simple but for some reason it isn't working… I have an attribute P1 that I want to use in the distance scale of my polyextrude. For some reason the extrusions are infinite. Does anybody know why is that? cheers! extrusion.hipnc
  9. Hi!! I have subdivided the primitives of an icosaedron. What I want is for each primitive, to select a random number of subdivisions (the small black triangles) , extrude them and control their density with an attribute. How can I do that?? POPULATION -HAPPINESS.hipnc
  10. Hi there!! I want to work between frames, that means I want to do some calculations in t=1/frame 1 that will affect values of t=2/ frame 2. More presicely I am importing csv files that show happiness numbers per 50 years. For t = 1, happiness = x. What I want is to say that when t = 2 and happiness = y, substract from happiness 10% of its value, i.e. happiness = y - y*y%. In the end I want to apply this policy to all the coming frames; if (factor < 5%) { @hapiness -= hapiness*10%; } How can I do that?
  11. Hello!! I am working in a triangulated sphere and I want to make the different triangles glow with different idensity according to their primitive attributes. Any ideas? thanks!
  12. And how can i do that? Should I use some specific sop? Can you ypload an example? - maybe the question is silly but I am still struggling with the software-
  13. Hello!! I am new in Houdini, so I need your help! How can I smooth the transition of an extrusion? -I don't want the extruded pieces to suddenly pop up, instead I want the procedure to be done gradually- thanks
  14. Hi! I want to trace the adjacent triangles of an icosahedron in order to find the average of their values and equalize them. Any ideas? neighbors multiple values.hipnc
  15. Hi there! I really need some help because I am new in Houdini! I am working in a triangulated icosahedron. I have a list of neighboring triangles and attributes stored in each of the icosahedron primitives. I want to get the average of those attributes per neighborhood and then I want to invent a formula in order to make them more equal. - if the attribute of one triangle is really high and its neighbors really low, then I want some % of the attribute from the higher triangle to transfer to that of the lower-. thanks neighbors multiple values.hipnc
  16. FIND NEIGHBORS OF PRIMS HOUDINI

    Dan, one more question. It seems that now I have a list of points and a list of primitives with 5 attributes instead of three. I guess it is because I found the adjacent points. How can I create a list with the adjacent primitives - triangles?
  17. FIND NEIGHBORS OF PRIMS HOUDINI

    Oh yes, I keep forgetting that! thanks a lot! It works great!!
  18. FIND NEIGHBORS OF PRIMS HOUDINI

    Thank you very much Dan! Now, I am able to see the list of the neighbours on points but still, I can't see it in the primitives. Do you know what can be wrong?
  19. Hi there! I have just started with Houdini. I have already tryied to transfer data from a csv file to the triangles of a triangulated globe. Then I' ve colored this data and I've extruded the data according to the values of the csv files. Now what I want to do is to be able to manipulate this data. ex. If a specific value from one triangle is really high, when its neighbours is really low, I want to give some % of the higher value (triangle1) to the lower (triangle2). How can I do that? I' ve attached pictures of the modules and the simulation model. thanks!
