How to connect points of PFI with wireframe?

Beginners

I’m quite new to touchdesigner, and I want to model a humanoid 3D model I have with a wireframe. However, whatever method I use seems to just apply a point sprite to each co-ordinate of the file, rather than connecting them in a wireframe. I have tried phong with wireframe enabled, wireframe, line and constant MATs and all do the same. Can anyone suggests how to achieve this? Any help will be much appreciated :slight_smile:

To clarify, I have instanced the GEO I’m using with the PFI coordinates, and used an add + convert SOP as the GEO input. I understand this may be the issue, but if it is how do I address this?

Hi @FinnJOrchard,

it sounds like what’s happening is that you are instancing a point onto the points of the 3D model. So the geometry now being rendered is a collection of points.

To render the model instead, turn off instancing and connect the SOP that brought in the model to a Geo COMP.

Hi! Thanks for the reply. That makes sense, but the PFI input is a TOP not a SOP so surely it wont work if I just connect it straight to the GEO, no?

Thanks

Hi @FinnJOrchard,

I missed that PFI means Point File In TOP, can you not bring the geometry in via a File In SOP?
There is no native operation in TouchDesigner to remesh a pointcloud.

No problem! And ahhh I completely neglected the fact that there is a file in SOP, but you have taught me something there too, haha. Thank you so much! Got it working how I want now :slight_smile:
