XRT 1.0.2 released

XRT 1.0.2 features a new generator plugin for PLY files loading. It is based on the RPly library from Diego Nehab (available here).

To stress the generator, I have hand translated some test scenes from LuxRays1 to Pyg. I have also updated XRT Python binding to enable object instancing within Pyg and redesigned a bit area lights to use geometry sets.

PLY geometry import works flawlessly but, given that XRT has no support for global illumination, the result is sometimes not convincing. Surface shaders could also be improved. Nevertheless, a few preliminary pictures are available here.

As usual, this new release along with the updated documentation is available in the Downloads section.

XRT 1.0.1 released

Structure Synth is a tool for generating 3D structures by specifying a design grammar (something akin to L-systems: a script with rewriting rules). Using simple rule sets, you can create very complex objects which looks like futuristic buildings, organic structures or abstract sculptures. It features a flexible template based export system for integration with third-party renderers. I believe this capability combined with SunFlow stunning renderings contributed a lot to its fame.

Of course, I could not resist writing a similar export template for XRT. It exports Structure Synth camera settings and shades the geometry with an ambient occlusion shader. To ease the process, I have added a Python binding for XRT LookAt API call bumping XRT version to 1.0.1.

This new release along with the exporter, the shader and the updated documentation is available in the Downloads section.

A new section of the gallery dedicated to Structure Synth is now available here.
