Change log¶
fresnel releases follow semantic versioning.
v0.6.0 (2018-07-06)¶
- Implement
tracer.Path
on the GPU. - Implement
ConvexPolyhedron
geometry on the GPU. - Improve path tracer performance with Russian roulette termination.
- Compile warning-free.
- Fix sphere intersection test bugs on the GPU.
tracer.Path
now correctly starts sampling over when resized.- Wrap C++ code with pybind 2.2
- Make documentation available on readthedocs: http://fresnel.readthedocs.io
- Fresnel is now available on conda-forge: https://anaconda.org/conda-forge/fresnel
- embree >= 3.0 is now required for CPU support
- Improve documentation
v0.5.0 (2017-07-27)¶
- Add new lighting setups
lightbox
cloudy
ring
- Adjust brightness of lights in existing setups
- Remove
clearcoat
material parameter - Add
spec_trans
material parameter - Add
Path
tracer to render scenes with indirect lighting, reflections, and transparency (CPU-only) - Add
ConvexPolyhedron
geometry (CPU-only, beta API, subject to change) - Add
fresnel.preview
function to easily generatePreview
traced renders with one line - Add
fresnel.pathtrace
function to easily generatePath
traced renders with one line - Add anti-aliasing (always on for the
Path
tracer,set aa_level
> 0 to enable forPreview
) - API breaking changes:
render
no longer exists. Usepreview
orpathtrace
.tracer.Direct
is nowtracer.Preview
.
CPU-only features will be implemented on the GPU in a future release.
v0.4.0 (2017-04-03)¶
- Enforce requirement: Embree >= 2.10.0
- Enforce requirement Pybind =1.8.1
- Enforce requirement TBB >= 4.3
- Rewrite camera API, add camera.fit to fit the scene
- scenes default to an automatic fit camera
- Implement area lights, add default lighting setups
Scene
now supports up to 4 lights, specified in camera space- Implement Disney’s principled BRDF
Tracer.histogram
computes a histogram of the rendered imageTracer.enable_highlight_warning
highlights overexposed pixels with a given warning colorDevice.available_modes
lists the available execution modesDevice.available_gpus
lists the available GPUsDevice
can now be limited to n GPUs- API breaking changes:
camera.Orthographic
is nowcamera.orthographic
Device
now takes the argument n instead of limitScene
no longer has alight_direction
member
