3Delight Studio Pro 11

June July 2013

Features

• Relighting: 3Delight is now able to continuously rendering scenes while accepting updates. For Maya users, this means IPR support and for Softimage users it means real-time render view updates.
• Introducing multiple-importance sampling to the trace() shadeop. This allows easy development of physically-plausible materials.
• New subsurface algorithms improves performance (up to 10x faster in global illumination contexts) and renders crisper images.
• Out-of-the-box support for MARI textures (UDIMs).
• Statistics in the multi-threading case are as precise as in the single-threaded case.

...

• Ray-tracing performance has been improved to such a degree that we now recommend using the ray-tracing hider as the default renderer for scenes with highly complex geometry (instead of REYES). Users can expect gains up to 20x faster when using multi-bounce global illumination and glossy reflections.
• Ray-tracing of motion-blur, even in the most extreme cases, is not a problem anymore. Performance is such that there are no objectionable speed differences between motion-blurred and static frames.
• Ray-tracing of dense and translucent surfaces, such as hair, is up to 3x faster.
• Ray-tracer startup time has been diminished. Space partition build has been multi-threaded and other, geometry specif optimizations, have been implemented.
• Sampling in the ray tracing algorithm has been greatly improved. This means that less samples are needed to obtain noise-free images, especially with image based lighting. 
• Subsurface scattering is 5x faster when combined with the path tracer. 
• Multi-threading scalability have been improved for both the REYES rendering algorithm as well as in the path tracer.
• Better multi-threading of texture reads. This can drastically improve render times when using a very large amount of texture files. We measured improvements of up to 25% faster.
• Rendering dense volume clouds (region with many interior shaders) is up to 2.5x faster.
• Point-cloud writing is now multi-threades.
• Shader compiler produces better code and is able to use up to 50% less varying variables as before. This translate to faster renders.
• Access to very large files have been improved by using memory mapped I/O when possible. This is especially useful when accessing large point-based files.
• Memory usage usage for very large polygonal meshes. We measured up to 4x less memory used on some typical production scenes.

• tdlmake is 2x faster.

i-display

i-display has been inproved to provide users with a more complete image viewing software. In this release, it provides the following improvements:

1. Thumbnails view.
2. Sequence management (deleting and moving images).
3. AOV viewing.
4. Image bookmarking.
5. Overhaul of the menu items and shortcuts to make i-display more consistent and easier to use and learn.

...

• Implemented the Rtx Plug-in interface. Meaning that users can provide reading functionality for their own texture formats.
• Curves now accept ’vertex’ width parameters (and not only ’varying’ as before). .

Documentation

• Online documentation has been improved and is now available through a new Wiki.

3Delight Studio Pro 10

August 2011

...

• A new point-based global illumination algorithm gives very high quality results and supports transparency, a first for this class of algorithms.
• Added support for Ptextures.
• Added support for multi-channel EXRs. Writing such files doesn’t require the installation of additional libraries anymore.
• Per-frame shading for multi-segment motion-blur can greatly improve performance.
• Point-cloud baking process produces a more even distribution of points and the IO (reading and writing PTC files) has been multi-threaded.
• Point-based occlusion() and indirectdiffuse() can receive a list of input files. An example usage is to separate static and dynamic elements for a more efficient baking process.
• Introducing dynamic output variables (using the new outputchannel() shadeop). This unique feature enables shader writers to create output variables on-the-fly inside shaders, lights and co-shaders. Along with the previously available “display subsets”, this feature adds unparalleled flexibility to layer-oriented rendering.
• Added ability to use OpenEXR image files directly as textures. Additionally, arbitrary “tags” can be passed to the OpenEXR display driver.
• The ray-trace hider can now render in progressive mode. This makes it more suitable for faster lighting work.
• Multi-camera rendering can now shade grids once per camera to correctly render view-dependent illumination such as reflections and specular highlights. This feature, unique to 3Delight, can be enabled on a per-primitive basis using an attribute.
• The renderer accepts a list of cameras to act as “dicing cameras”. For some particular geometry, 3Delight will use the most suitable camera to perform the dicing. This feature can be used to properly bake geometry in preparation for a fly-through (by providing a number of dicing cameras along the fly-through path).
• The subsurface scattering algorithm has been considerably improved: varying absorption and scattering properties are now accepted, artifacts resulting from low point density are fixed and memory usage has been cut by half. Additionally, the pre-processing phase has been multi-threaded for a reduced “time to first pixel”.
• Ray-tracer’s building phase has been multi-threaded. Furthermore, the ray-tracer now supports features that were only available in REYES such as AOVs and matte objects.
• Photon mapping quality has been greatly improved and photon maps are now 50% smaller. The photon-casting process has been multi-threaded. Speed improvement is linear with the number of cores.
• Texture mapping blur quality (during texture() calls) has been improved.
• Additional improvements include better tessellation quality for subdivision meshes, better non-raster oriented dicing and better distributions of rays for ray-tracing functions.
• Added ability to read and write TIFF textures larger than 4GB.

...

Pipeline & APIs

• Introducing the 3Delight Gx API for evaluation of arbitrary geometry and attached primitive variables. This very simple API allows the user to evaluate any geometry supported by 3Delight (including subdivision surfaces). Geometry can be evaluated both during an ongoing render or separately from any rendering context. This makes 3Delight usable as a general purpose geometry evaluation library.
• The 3Delight Sx API (for shader evaluation) has been improved and now supports co-shaders. The API is also mutli-thread safe.

...

• A new unlimited-threads license is now available for both the 3Delight standalone the 3Delight standalone renderer and the 3Delight the 3Delight for Maya plugMaya plug-in. Clients that purchased the 8-thread license (and under yearly support) are automatically upgraded to unlimited-threads. The 8-thread license will no longer be available, but the 4-threads and 2-threads will continue to be available at a reduced pricing.

...

• Introducing multi-camera rendering. This features enables the output of many camera views from a single render. This functionality is especially useful for stereo rendering as it saves rendering time.
• Improvements to point-based occlusion quality: concave corners are rendered more accurately.
• The subsurface shadeop can proceed from a point-cloud file. This can save a potentially costly pre-processing step when rendering sequences.
• Billboard particles can now be rendered with a “thickness” for correct shadow casting.
• Network caching, a feature unique to 3Delightto 3Delight, is now available on Windows systems.
• Added detailed memory statistics to 3Delight to to 3Delight to better track memory usage.

...

• Introducing the “VolumeTracer” API. This RSL plug-in allows user to easily write volume renderers.
• The “Sx” shader evaluation API is now embedded with the 3Delight library the 3Delight library (takes a single 3Delight license single 3Delight license when used).
• Added “Implicit Field” plug-in support (extension to the RiBlobby primitive).
• Display drivers can now access 3Delight’s deep frame buffer which provides the list of visible surfaces for each pixel sample.
• Added new entries to the Ptc API and fixed compatibility issues.
• RiNuCurves now support vertex normals.

...

• Introducing the 3Delight Relationship Editor. This new user interface replaces the now deprecated Shader Manager and Attribs Node Manager and makes it much easier to view, assign and modify3Delight shaders and attributes, in a centralized location. The usability of shader and attribute collections is substantially improved thanks to this same feature and one can inspect, for each pass and at a glance, what attributes and shaders are in effect.
• Introducing “Pass Templates” It is now possible to save a given render pass as a template and create new passes based on existing templates.
• A new "round edge" features enables automatic edge rounding of sharp geometric features. Using this feature, one can round edges at render time (such as a table edge) instead of performing a costly modeling-time operator.
• Added a “dicing camera” "€œdicing camera"€ attribute in the geometry attributes node (in the “Culling and Dicing” "€œCulling and Dicing"€ section). This features is useful to stabilize popping displacement during animation.
• Updates to HyperShade:

...

• Array support has been added to the Ptc API. This also means that texture3d() and bake3d() accept array parameters.
• Helper functions have been added to the Display Driver API.

Shader Compiler

• 3Delight now supports co-shaders (as per RSL 2.0) and completes the implementation of shader classes.
