Future Plans

BBM is a work in progress. Here we list the plans for the next immediate versions (subject to change) as well as unscheduled plans for longer term changes:

Version 0.5.2

• Improvements to Python interface for passing parameters to differentiable and packet types.

• Packet support for DRJIT

• Better Python support for DRJIT

Version 0.5.3

• Holzschuch and Pacaknowski’s two-scale microfacet reflectance model

• The ‘Dinsey BSDF model <https://media.disneyanimation.com/uploads/production/publication_asset/48/asset/s2012_pbs_disney_brdf_notes_v3.pdf>_

Version 0.5.4

• More robust auto-diff support with DRJIT and Enoki

• Gradient based BSDF fitting

Version 0.6.0

• Spatially varying BSDFs

• Improved vectorization support

Version 0.7.0

• BSDF fitting strategies: implementation of various published fitting strategies

Not yet scheduled/wish-list

• Improved Python support; allow for Python BSDF

• DRJIT/Enoki GPU support

• Mitsuba 2/3 exporter

• PyTorch bindings

• PBRT exporter

• Support for other measured static BSDF models

• Multi-spectral support

• Data-driven masking and shadowing for NDFs with no analytical solution

• Data-driven reflectance for BSDF models without an anaitical solution
