Sorbetto Relighting Tool

Ok if you don't have access to Pixar relighting toolset lpics like this...Sorbetto is a nice relighting tool which seems to be similar. It comes as part of the Gelato renderer.
Its FREE so no harm in giving it a go...A proviso is you will need to have a suitable nvidia graphics card.

3delight 8.5 Out Now

Info (Copy and Paste)

This release includes support for RSL 2.0 (shader objects and co-shaders) and further ray-tracing optimizations that should give significant performance gains when rendering displacements and motion-blur. 3Delight For Maya includes a new relationship editor to quickly explore and assign shaders and attributes as well as new "edge rounding" features to easily bevel edges on polygonal geometry.

zdepth in 3delight

Hello Atom,
I am new to 3delight as i've been using m.ray for a long, long time. I was wounding if u have a moment to explain in the basic terms how to set up z depth that would give me optimal results in 3Dlight ? Any help would be much appreciated.
With Respect Dantes.

-------------------------
Hi Dantes, who is atom? apologies in answering your email so late
try this.

1) select in secondary Displays in 3delight renderpass - Display AOV - luminance depth
2) set the far clip plane close enough under the camera attributes to a suitable distance. maybe the distance of the furthest geometry.
........... or
or use a 32bit z pass and extract the data you need in your compositing tool - you have much more control :) - swag

AMBIENT OCCLUSION POINT CLOUDS with deformations

AMBIENT OCCLUSION POINT CLOUD BAKING

1. Attach ptc_write shader to geometry, put in output name in eg "scene.ptc"
2. set attribute on geometry in 3delight- cull hidden surfaces, cull backfacing surfaces, raster orientated dicing to off
3. set up camera view to encompass the geometry
4. Render settings: Quality - Pixel Samples 1,1 Pixel Filter - Box Filter
, top camera. the quality can be cack cause your outputting the point cloud.
5. Render out .ptc file
6 Open ptc view and have a look at the .ptc file. spin it around like a crazy fool.
5 create bkm ( brickmap) file from ptc on command line put in ptc2brick "C:\scene.ptc" "C:\scene.bkm"
There other commands you can put in to vary quality etc, but that will get you going.
6, Attach bake_occlusion_Pref shader to geometry. Put in scene.bkm into the shader.
7 set bias in shader low to avoid white creases
, set the other setting how you see fit.
8. set attribute on geometry - cull hidden surfaces, cull backfacing surfaces, raster orientated dicing to on
set 3delight geometry attribute Visibilty to diffuse Rays(occlusion) Shader Color & opacity
10 Reset the rendering quality setting to the default or whatever you want.

POINT CLOUD BAKING FOR GEOMETRY THAT IS GOING TO DEFORM
1) Select Geometry - Maya Menu - Rendering - Texturing - Create Texture ref object.
2) Add attribute Reference Geometry in 3delight, output Pref, output Nref

3) Follow steps 2-10 above

shader (modified following instructions by mkesson, check out the 2 previous entry)

surface
bake_occlusion_Pref
(
string bake_file = "";
float maxtDist = 1;
float samples = 64;
float bias = 0.05;
varying point Pref=(0,0,0);
)
{
extern point Pref;
extern normal N;
normal Nn = normalize(N);
color ao = occlusion ( Pref, Nn, samples, "maxdist", maxtDist, "bias", bias );
ao = 1 - ao;
bake ( bake_file, s, t, ao );
Ci = ao;
Oi = 1;

Hi,
this is my basic tutorial for a simple occlusion pass.

Hi guys,
this is my basic tutorial for a simple deep shadows workflow...special thanks for olivier, jmxd and lazzhar for help me (post of colored shadows).

New Book

I ponied up for this book. Put together by Rudy from RendermanAcademy fame and Saty Raghavachary,I would say its worth your time. Only minus point is there isnt a included CD-ROM or website that works with all the shaders. Apart from that ace.

3Delight 7.0 and 3Delight For Maya 3.0 released

This is a blatant copy and paste!!!


Original message via Google News.
Remember that the first full license of the renderer is free!
Some of the most important features and improvements:

3Delight

Rendering Features

* New Image Based Lighting Algorithm. A more flexible and powerful approach to image based lighting is introduced.
* Point Based Occlusion and Color Bleeding.
* Brick Maps (3D Textures) for efficient and anti-aliased 3D data lookup.
* Display subsets. A unique feature that enables rendering of many layers, each with its own alpha channel and output variables, in one render pass.

Performance

* Multi-threading efficiency has been improved for scenes with high depth complexity.
* Point cloud files are not read in memory all at once any more: proper caching enables memory-efficient access to point cloud data.
* Subsurface scattering has been optimized and the pre-processing step is now run in multi-threaded mode.
* Deep Shadow Map creation is now multi-threaded.
* occlusion() and indirectdiffuse() have been accelerated through the use of adaptive sampling.

Texture Converter (tdlmake)

* A new -preview option makes textures appear as TIFFs of lower resolution to software such as Maya; this enables you to use a single texture for both Maya previews and final renders. Additionally, tdlmake now supports the TARGA file format.

New Tools

* ptc2brick is a tool to convert point cloud files to brick maps.
* ptcview is a tool to view point cloud files.
* ptcmerge is a tool to merge point cloud files.

Pipeline

* A new API to access point cloud files is available.
* A more advanced C++ API for DSO plug-ins is available.

3Delight For Maya

* The plug-in is better integrated into Maya. It now registers itself as a standard Maya renderer and is thus accessible through the Render Settings. Batch rendering and command line rendering (through the standard Maya Render command) is now possible.

* Improved HyperShade Translation:
o 3Delight For Maya tracks HyperShade network modifications and only translates and compiles shaders which have changed.
o The following hypershade nodes are now supported: ocean, remapValue, lightInfo, layeredTexture and volumeLight.
o The Image Sequence options of the File texture node are now upported.
o HyperShade networks for light sources are correctly translated into their RenderMan SL equivalent.
o The RenderMan Code shader can now declare output variables and those can be output using secondary displays (advanced).

* Support for RIB archives creation and reading using a user friendly, yet flexible, interface.
* Out-of-the-box support for Shave & a Haircut and much improved Maya Fur support.
* Object Instancers are fully supported.
* Shadow Maps can be rendered using arbitrary cameras. This allows for better shadow map view framing and thus better quality.
* More output variables added to secondary displays.
* Maya 2008 support.

ANISOTROPIC Shader

Hi,
nice blog!
I have create this shader for my work, for silk, velvet and aniso -
metal....(based on some shader of Renderman Sigg. couse)
it is not like a Bertrand's best shader, but have a some tex multiply
option......
and works with polygons.

Test with low raytrace:
give a look.
ciao
