"A Torus Line"

Fast additive line-rendering in Mantra + DOF...

Best look at it in full size, scaling doesn't like it too well.

Cheers,

Tom

Very nice!  How did you derive the curve normals for the spec highlight?

In a mantrasurface you dive into the network after making it editable and then replace the two normal inputs in the main surface node with the output of a "Hair Normal" node, that will give it a roundish look.

And another one based on the setup by petz here:

I extended it a bit and got this:

Rhinos Grasshopper had pretty cool field line components, but this is even better - thank you petz!!!

This one is heavily post-processed in Photoshop with the "Oilpaint" filter. If you deactivate it's specular component, you basically get a directional blur which sometimes works great on images with clear lines.

The displacement texture is a modified version of this GLSL shader: https://www.shadertoy.com/view/XddSRX

I currently look into GLSL using this IDE: http://synthclipse.sourceforge.net/index.html

Otherwise its a simple displacement on a grid :-)

Cheers,

Tom

Thanks a lot for the info! That shadertoy site is awesome, lots to learn.

One last question, on the shader toy site there are 2 codes (Buf A and Image), by curious I tried putting in a wrangle but didnt work, there is any way to translate this stuff to houdini? 

Will read more about these sites, thanks again! and keep sharing your art!

Cheers

I made a big screenshot of the result after some time of painting in synthclipse... ;-)

There is a GLSL node in Houdini, but I think I read somewhere that it's for the viewport only.
Can't help you there, I haven't tried it yet.

Cheers,

Tom
