[edit] Features

3Delight primarily uses the REYES algorithm but is also fully capable of doing ray tracing and global illumination. The renderer is fully multi-threaded and also supports distributed rendering. This allows for accelerated rendering on multi-CPU hosts or environments where a large number of computers are joined into a grid.

It implements all required capabilities for a RenderMan-compliant renderer and also the following optional ones:

Area light sources
Bump mapping
Depth of field
Displacement mapping
Environment mapping
Global illumination
Level of detail
Motion blur
Programmable shading
Special camera projections (through the raytrace hider)
Ray tracing
Shadow depth mapping
Solid modeling
Texture mapping
Volume shading

3Delight also supports the following capabilities, which are not part of any capabilities list:

Photon mapping
Point clouds
Hierarchical subdivision surfaces
NURB curves
Brick maps (3 dimensional, mip-mapped textures)

[edit] Modules

3Delight is based on modules. The primary module is the REYES module which implements a REYES scanline-like renderer.

The second most important module is probably the ray-tracing one, called 'Sabretooth' which also supports global illumination calculations through certain shadeops.

3Delight supports explicit ray tracing of camera rays by selecting a different hider, essentially turning the renderer from a hybrid REYES/ray tracing one into a full ray-tracer.

Other noteworthy features include:

Extended display functionality to allow rendering an unlimited number of exclusive passes
Exclusive meaning that coverage information from other passes can be ignored and then will not mask a pass.
First order ray differentials on any ray fired from within a shader

[edit] History

Work on 3Delight started in 1999. The renderer became first publicly available in 2000^[1].

3Delight was meant to be a commercial product from the beginning. However, DNASoft decided to make it available free of charge from August 2000 to March 2005 in order to build a user base.

During this time, customers using a large number of licenses on their sites or requiring excessive support were asked to kindly work out an agreement with DNASoft that specified some form of fiscal compensation for this.

In March 2005, the license was changed. The first license is still free. From the second license onwards, the renderer is 1,000 USD per node; with a node supporting a maximum of two CPUs.
