# How to make a spiked sphere?

I know how to make it manually with cone rotation around the sphere. but maybe there's much simpler solution or addon that has that option, preferably not very high poly solution.

Also if possible I would like the spikes not to be very pointy if that makes any sense

Here is what I kinda have in mind

Thanks

If you want to model it as a one mesh you may achieve it beveling the Ico Sphere.

Add the Ico Sphere (Shift+A-->Ico Sphere) with the 3 subdivisions.

In Edit Mode (with edge selection type) select the whole mesh (A), press Ctrl+B, then V to bevel the vertices only. With a cursor placed in the middle of the mesh and a pivot center type set to 3D Cursor extrude selected elements and then scale them (E,S). Next change the pivot center type to Individual Origins and scale all tips with S.

Give the object the Subsurf Modifier. Select the edge loop at the bottom of the spike, click Select-->Select Similiar-->Face Angles. Then press Shift+E to crease them.

• Hey what software did you use to do the screen-caps? I like the box showing input. – beppe9000 Jun 23 '16 at 22:08
• @beppe9000 I use LICEcap. I highly recommend it to you. For other solutions please check out this post:: meta.blender.stackexchange.com/questions/963/… – Paul Gonet Jun 23 '16 at 22:11
• @beppe9000 - If you're referring to the screencast keys (mouse and key presses), that an add-on that comes with Blender. – Chris Dunaway Jun 24 '16 at 16:25
• @ChrisDunaway and beppe9000 Blender has removed the screencast key addon (somewhere around 2.70 I think). See this answer for how to get them back. – Gliderman Jun 25 '16 at 14:46
• @PaulGonet Nitpicking: you've missed the small notches around the spikes ;) – p2or Jun 28 '16 at 20:48

You can easily do it with Dupliverts if you don't need a single continuous mesh surface.

Model your spikes however big and rounded you want them to be as any independent mesh object; you may need to rotate them $$-90º$$ in the X axis so they point up towards $$Y+$$ axis.

Parent it to an icosphere with Ctrl+P and activate the option Dupliverts in the Properties Window > Object > Duplication > Verts also activate Rotation.

Adjust the subdivision non destructively with a Subdivide modifier and then control the scale of the spikes.

You can still adjust the spikes independently by editing the original spike object.

• Ok i followed it, its kinda fast to me all is fine until i check the rotation checkbox then all spikes goes randomly different directions – notverybright Jun 23 '16 at 18:46
• You have to modify the cone in edit mode to make it match the expected rotation so all spikes point outwards. For me rotation in edit mode -90º in the X axis did it fine. Make sure you apply the ration and scale to the cone – Duarte Farrajota Ramos Jun 23 '16 at 18:50
• Thanks i think i got it. Just need to practice. Thank you for your time Oh. how can i make it as solid object? if i delete the cone inside the sphere it deletes all the spikes – notverybright Jun 23 '16 at 19:04
• You can use the Operator "Make Duplicates Real" search for it in the spacebar menu or use Shift + Ctrl + A – Duarte Farrajota Ramos Jun 23 '16 at 19:20

You could also use the Poke tool. Start with an icosphere, go into edit mode, select all, then use Alt-P. In the Tools panel on the left, at the bottom, you can adjust how much they stick in or out, or use F6 to bring up its options.
