## Description Both the `uniform` and `regular` plugins take wavelength range parameters. However, `uniform` uses the `wavelength_min` and `wavelength_max` names, while `regular` uses `lambda_min` and `lambda_max`. For consistency (also with...

[🐛 bug report] Incorrect radiance values using the `radiancemeter` plugin

17

## Summary I get wrong radiance values with a simple setup consisting of a homogeneous volume above a flat surface. ## System configuration - Platform: macOS 12.1 - Compiler: Apple...

Add eval(), sample_direction() and pdf_direction() to distant sensor

6

## Description This PR implements the missing `eval()`, `sample_direction()` and `pdf_direction()` methods for the distant sensor plugin. **Notes**: - Not ready for merge, requires decision regarding `SurfaceInteraction3f`. Depending on the...

[Feature] Hemispherical distant sensor plugin

15

## Description This PR adds a hemispherical distant sensor, which is similar to an adjoint to the `envmap` emitter. It records radiance leaving the scene in a hemisphere. It can...

## Description I'm using Dr.Jit on a machine without a CUDA-enabled device. I made sure to set `export CUDA_VISIBLE_DEVICES=""`, but I'm still getting the following warning message upon import: ```...

This PR adds resources required to compile the documentation for the `hdistant` plugin. Plots are hopefully reproducible. Schematics are created with Inkscape. To address display issues in Firefox (arrow heads...

Distant sensor plugin

13

Co-authored-by: @schunkes This PR adds a distant directional sensor plugin similar the distant directional emitter. It is useful to record radiance leaving the scene and compute, in practice, the BRDF...

Flexible spectral sampling for sensors

7

This PR adds flexible spectral sampling for sensors as discussed in #127. Changes are as follows. I only added it to the `perspective` sensor plugin so far, I'll add this...

Ray intersection sometimes ends up behind shape surface with inaccuracy larger than shadow epsilon

6

Ray intersection is sometimes behind surface with inaccuracy larger than shadow epsilon. This may result in wrong occlusion. ## System configuration Platform: macOS 10.15.4 Compiler: Apple clang version 11.0.0 (clang-1100.0.33.17)...
