Medical Model Virus- Floating Hair Instances


#1

Hi - I’m populating the outside of a sphere with models - using ‘hair instances’ I attach an example:

However my instances are not penetrating the ground surface / sphere. Does anyone know if it’s possible to move them somehow?

I’m using a hair object and using ‘polygon center’ to position my models onto the sphere mesh…

Hope someone knows…

Nick

Sorry found solution - under hairs in hair object - Roots and ‘offset’ u can move them…

Cool looking spike proteins :slight_smile:

Using a mograph cloner would work much better in this context, and you would have all the control, you need over offsets, rotation etc. And you could use the awesome suite of effectors to modify or animate the instances.

Here’s a recent example I created: SARS-CoV-2

was wondering why you went with hairs for distribution as well. Are you looking to get dynamic/organic waviness in the spikes?

Real nice work Mr NWoolridge.

Very cool animation thanks for sharing - I think you’re actually quite accurate with your spikes looking at the virus under a microscope :slight_smile:

I’,m coming from Maya and am new to Cinema 4D - only had it for 4 months. In future I’ll go with a Cloner looking at your animation - however hairs have worked quite nicely for me - you can grow off of your selections and drop or delete hair instances where u want … however I can’t texture the instances …

yeh I’m going to animate a group of them with deformations on the sphere and slight waviness on the spikes - and also show the inside like with NWoolridge.

Nice. I will unabashedly throw my hat into the ring as well :slight_smile: Heres ours.

Cool :slight_smile:

Hi - sorry one question with the cloner option: how do you get your clones to point outwards from the normal of your object ?


#11

They should do that automatically depending on what Cloner settings you are using, however, you may also need to go to the Transform tab for the Cloner Object and alter the Pitch (usually) or Heading or Banking rotation to get it as desired. You may also need to make any primitives you’re using editable.

If that doesn’t resolve it for you, can you upload a test file that shows the problem.

Hi,

Thanks that’s kind of you - I attach an example scene file -

and this is the problem below:

Sorry found solution - like Drew Ker said - you change the rotation in Transform but also make sure your pivot point is at the base of your object. Thanks anyway :slight_smile:


#14

You should probably make the angle rotation mathematically precise in your example by changing R.P to 90° and R.B to 0°. If you chose those rotation angles for artistic reasons, ignore this post.

Glad you got it working :slight_smile:

Yeh the 1 degree slight rotation along one axis was an artistic choice :slight_smile:
