Blender - Array along Curve

Recommended Posts

Hello I am mainly a blender users. I would like to learn Houdini, it's procedural and non-destructive workflow is quite appealing to me.

In blender it is quite easy to create an array along a curve. It is also easy to project a curve onto a surface. I would like some help with creating something in Houdini.

I have created a piece of a wall. It is a small tillable section of the wall.

this is a single mesh that I exported from blender. I also have a terrain. I know how to draw curves in Houdini. I would like to create an array of the wall along the curve. Also how can I project the curve on to the underlying terrain?

Thanks Poen. Your approach to the problem is interesting. Unfortunately it does not orient the wall to the path, it just copies the y axis position.

Hi!

 

Have you found solution to your problem? I'm also missing this usefull easy to use modifier :)  I'm mainly missing coping GEO with exact distance, to make an seamless array.

 

I found this: http://www.sidefx.com/index.php?option=com_content&task=view&id=1242&Itemid=255

 

 

cheers to fellow blender user :)

If you need an exact distance between points you can use the resample SOP. In the resample you can specifiy the maximum length of a single segment.

checkout the creep sop :)
then make planes that are connected and it will put the bricks together distorting that as required.

The creep node is a bit more complex to use though

(having the correct 0.5,0.5 offset and the correct polygon orientation),

and probably a bit slower than a direct copy.

 

But it will indeed take care of the deformation.

So if you need this fidelity the creep sop is probably the way to go.

 

For quick and dirty results,

 

Resampling the Raycasted curve and possibly smoothing it,

should more or less give you the blender result.
