Instance Noodles update: Alpha 0.3 "Tonkotsu"

New Noodles: Alpha 0.3 "Tonkotsu"

Some new & improved nodes + bugfixes but the tasty new flavors are Noise & CSG implementations.

Noise

New textureless magic noise suite based largely on the great GLSL postings of http://briansharpe.wordpress.com/
to use in a shader see InstanceNoodles\nodes\modules\Common\NoodleNoise.fxh
Of course there are nodes for people that don't want to mess with shader code though.

Includes 2D and 3D Perlin, Simplex and Worley, all with single octave noise as well as FBM, Turbulence & Ridge flavors. Worley comes with various distance metrics & cell functions. To get an idea of the (many) Worley combinations here's a nice reference:

CSG

Constructive Solid Geometry finally... Realtime implementation using distance fields stored in 3D textures or 'volumes'. Picture speaks a thousand words:

As well as the standard Union, Intersection & Difference operations as pictured above, 16(!) other combination operations ported from the very sexy GLSL raymarch lib: http://mercury.sexy/hg_sdf/

New DX11.TextureFX nodes

Noise3D (DX11.TextureFX)

New Compute nodes

Noise2D (Value Buffer)
Noise3D (Value Buffer)
NoiseDerivs2D (Value Buffer)
NoiseDerivs3D (Value Buffer)
min (Value Buffer)
max (Value Buffer)
S+H (Vaule, 2D, 3D, 4D versions)
SumUp (Vaule Buffer)
Vector4DSplit (Vaule Buffer)
Normalize (3D Buffer)

New DX11.Geometry nodes

Kinect2GS (DX11.Geometry) kinect2 texture maps to mesh, with optional player filtering
SplineTrails (DX11.Geometry)
SplineBuffered (DX11.Geometry) now has ribbon mode
SDFtoMesh (DX11 Geometry) conversion of signed distance fields (as 3D texture) to mesh using marching cubes. This allows constructive solid geometry to be integrated with normal geometry pipeline

New DX11.Volume nodes (mostly for CSG ops)

CombineSDF (DX11.Volume)
BoxSDF (DX11.Volume)
SphereSDF (DX11.Volume)
TorusSDF (DX11.Volume)
CylinderSDF (DX11.Volume)
PrismSDF (DX11.Volume)
ExtrudeTextureSDF (DX11.Volume)
NoiseSDF (DX11.Volume)
Resize (DX11.Volume)

for fast peek at the results:

PreviewVolume (DX11.Layer)

Changed /fixed Nodes
DX11.GeomFX modules now have max elements pin. Set to 0 by defualt, which will use the old automatic behavior, or any other positive number for manual setting

+ various small bug fixes that I'm too lazy to type.

Wow..incredible stuff. Thanks so much for sharing!

tekcor 23/07/2016 - 15:53

wow big up for the work!!

CSG... how hard was that?

u7angel 23/07/2016 - 20:05

do you have a CSG demo patch ? cheers...

everyoneishappy 24/07/2016 - 03:39

@tekor
well it's a fairly naive implementation, you may find the resolution to be a limiting factor. But after playing with raymarching it was actually very easy to make.

@u7angel
check help patches for combineSDF or SDFtoMesh. Basically you can keep combining primitives with the combine node in a chain.

THANK YOU!!!!!

hm, for some reasons csgs dont render. neither with previewvolume nor with SDFtoMesh. No red nodes, no error messages...

GPU is GTX 980 Ti

@elektromeier
Someone else had that, we worked out that they were not having shader uint types come up as pins in patch. I'm not sure what the fix is for that yet (are you using current DX11?), but as a workaround you can change uint to int. So for example in SphereSDF change

uint tranformCount, radCount, maxCount;

int tranformCount, radCount, maxCount;

elektromeier 26/07/2016 - 12:07

was not using the most recent dx11 pack. installing version 0.6.1-x64 from here directx11-nodes-alpha solved the issue.

thx kyle.

thank you for this great update! sdfs! i´ve got problems: surface distortion shader throws error in line 71:...GET seems to be unknown.

downloaded the update twice to make sure: my fxh folder is empty. is this on purpose? shouldn´t the noise.fxh be in there?

allthebest, dd

everyoneishappy 04/08/2016 - 13:41

can change lines 71-73 to:

uv0 = uvMode.Map(p0,0,0)*scale+offset;
    uv1 = uvMode.Map(p1,0,0)*scale+offset;
    uv2 = uvMode.Map(p2,0,0)*scale+offset;

fixed for next release, thanks.

thank you! works perfectly.
