But are using a python script calling LuxCore API or still using Blender from command line ?

I guess I'm still using Blender from command line? It's like I just run "blender my_blend.blend -b -p my_script.py" It works in my local device but not remotely

I guess the scene was saved on a PC with 3 OpenCL devices, just go the the BlendLuxCore device panel, refresh the list and select your GPU :idea: Hi Dade, I met this exact problem, but in my case I'm trying to render through python script remotely, so I cannot open the Blender GUI to refresh the GP...

Hi Dade, the filter clamps all the wavelengths below ~700 nm, and our illumination is above 800 nm, so its actually not working in the visible range. Is this possible to be simulated? Not directly but it should be possible to workaround the problem: it is just a convection to interprete the 3 numbe...

Thank you, but I think its community is not as active as luxcore

How does the filter works exactly ? Are you still working only in the visible Spectrum ? If you filter just clamp the range wavelengths visible, you may need only to post process the final output of the rendering. I mean, for instance, if a filter clamp the wavelengths between 625–700nm (i.e. only ...

Hi, In my application, we use near infrared illumination light source and monochrome camera with long pass filters (wavelength below red will be filtered out), and we are trying to simulate that. I noticed Luxcore can transfer spectrum into RGB and then saved as BW in the rendered result, but is it ...

It is the light received by the surface, what the camera sees depends by other factors like the material and orientation of the seen surface. You need to multiply "c" for the dot product of the surface normal and shadow ray direction: this is the received light. Than you need to evaluate ...

ProjectionLight::Illuminate() takes a point a return the amount of light received and the shadow ray to trace to know if the light sources is visible. Assuming the light source is always visible, you need to integrate the values of ProjectionLight::Illuminate() over the surface you want to examine....

Yes, but over the complete projected area or on a point ? Anyway, it is math it is possible to derive from the model but to what porpoise ? For you it may may be just easier and to look at the values on the EXR output :idea: Over the complete projected area. I'm doing a projector simulation, and it...
