3Delight is a 3D computer graphics software that runs on Microsoft Windows, macOS (both Intel and Apple Silicon) and Linux (both x86 and Graviton). Developed by Illumination Research, it is both a photorealistic and NPR path tracing offline renderer based on its NSI API scene description and on Open_Shading_Language for shading. It has been used to render full CGI animation and VFX for numerous feature films. It comes with supported, open source plug-in integrations for several DCC applications, such as Autodesk Maya, Houdini, Cinema4D, Katana, OpenUSD Hydra, and a democratic free license that allows for commercial use. It also provides a fully distributed cloud rendering service called 3Delight Cloud.
History
[edit]Work on 3Delight started in 1999. The renderer became first publicly available in 2000.[1] 3Delight was the first RenderMan-compliant renderer combining the REYES algorithm with on-demand ray tracing.
The 3Delight team decided to make it available free of charge from August 2000 to March 2005 to build a user base. During this time, customers using a large number of licenses on their sites or requiring extensive support were asked provide fiscal compensation for this.
In March 2005, the license was changed. The first license was free and subsequent licenses cost 1,000 USD per two thread node and US$1,500 per four thread node. The first company that licensed 3Delight commercially was Rising Sun Pictures in early 2005.
Since 2018, all purchased licenses of 3DelightNSI are unlimited multi-core and the pricing was reduced to US$360 per year subscription or US$720 permanent with two year support. The first license is still free; initially limited to four cores/thread, later increased to eight and currently twelve.
As of 2018, Illumination Research, due to the aging of the Renderman Interface (RI), introduced the Nodal Scene Interface (NSI) that replaces the old Renderman one. To reflect such a change the name of the renderer has also been updated to 3DelightNSI. Consequently the new 3DelightNSI renderer is not Renderman-compliant anymore.
Features
[edit]Until version 10 (2013), 3Delight primarily used the REYES algorithm but was also capable of doing ray tracing and global illumination. As of version 11 (2014), 3Delight primarily used Path Tracing, with the option to use the REYES and RayTracing when needed. The 3Delight renderer was fully multi-threaded, supported RenderMan Shading Language (RSL) 1.0/2.0 with an optimized compiler and last stage JIT compilation. 3Delight always supported distributed rendering. This allows for accelerated rendering on multi-CPU hosts or environments where a large number of computers are joined into a grid / cloud. In 2018 3DelightNSI 1.0 was introduced as a forward path tracer based on the new NSI API and using OSL for all shaders and light emitters.
3Delight implements:
- Area light sources
- Depth of field
- Displacement mapping
- Environment mapping
- Global illumination
- Motion blur
- Programmable shading
- Camera projections
- Path tracing
- Spatial overrides
- Texture mapping
- Volume shading
- Hierarchical subdivision surfaces
Other features include:
- Extended display subset functionality to allow rendering of geometric primitives, writing to the same display variable, to different images.
For example, display subsets could be used to render the skin and fur of a creature to two separate images at once without the fur matting the skin passes. - Procedural geometry is instanced lazily even during ray tracing, keeping the memory requirements as low as possible.
- Displacement shaders can be stacked.
- Displacement shaders can (additionally) be run on the vertices of a geometric primitive, before that primitive is even shaded.
- First order ray differentials on any ray fired from within a shader.
- A read/write disk cache that allows the renderer to take strain off the network, when heavy scene data needs to be repeatedly distributed to clients on a render farm or image data sent back from such clients to a central storage server.
Supported platforms
[edit]- Apple macOS on both the x86-64 and Apple silicon architectures.
- Linux on the x86 and x86-64, architectures.
- Linux on the ARM64 architecture, on AWS Graviton.
- Microsoft Windows on the x86 and x86-64 architectures
Operating environments
[edit]The renderer comes in 64-bit versions, allowing the processing of very large scene datasets.
Discontinued platforms
[edit]Platforms supported in the past included:
- Digital Equipment Corporation Digital UNIX on the Alpha architecture
- Silicon Graphics IRIX on the MIPS architecture (might still be supported, on request)
- Sun Microsystems Solaris on the SPARC architecture
- The Cell architecture
- Apple Mac OS X on the PowerPC (the last version to support PPC architecture was version 9).
