Re: [Renderer Workbench] Lighting

I've completed support for Point Light in Cycles exporter. Here are my 2 scenes rendered with Cycles: CyclesProject9s6dauj_.png CyclesProjectu87azg7i.png Interestingly, there is no automatic smoothing in Cycles, so we can see small triangular sub-faces on the sphere... As a counterpart, details are ...

Re: [Renderer Workbench] Lighting

Studying again POV standard template, I finally added a skysphere to luxrender_standard.lxs template (called a 'constantinfinite' in SDL).

Then I was eventually able to render with Luxcore the 2 scenes I previously built for POV-Ray:

Re: [Renderer Workbench] Lighting

I eventually found some time to add support for point lights to Luxcore renderer (PR is here: https://github.com/FreeCAD/FreeCAD-render/pull/20)! Here is a simple scene (the same as previously used for POV): ball.png A few comments: - To be fully operational, this evolution requires that the PointLi...

Re: [Renderer Workbench] Lighting

Nice. This looks pretty cool already. Thank you! There is the directional light in the Arch Texture workbench. This should be a good fit for architectural projects. Sure! Directional lights could also be one of the lighting tools for rendering, they are very convenient to simulate sun. However, dir...

Re: [Renderer Workbench] Lighting

I finally posted a first PR, which allows a user to add Point Lights in a scene rendering. https://github.com/FreeCAD/FreeCAD-render/pull/18 For the moment, the export only works for Pov-Ray, but I will extend it to other rendering engines in the future. Usage: 1°) Add a Point Light to the FreeCAD s...

Re: [Renderer Workbench] Lighting

Good idea! So the targets for the lighting effort could be: - Point Lights (PL) - Area Lights (AL) - Image-Based Lighting (IBL) - Hosek-Wilkie Skylight (HWS) - A tri-point lighting functionality, based on PL and AL (priority 2) - Plus a Camera Object (CAM), to meet a need expressed here: https://for...

Re: Travis build failure

GCC 9 currently spams the log, some Eigen related info. This is no spam! Indeed, Eigen breaks the famous "rule-of-3" in some parts of its code, as it explicitly declares some copy-assignment constructors with no equivalent explicit copy constructors and this is no good practice (see https://en.cppr...
