Photo-realistic rendering of FreeCAD models with CADRays

[PrzemoF]

OK, thanks! I couldn't figure out why it doesn't see OCE on my laptop.. (I have 0 windows knowledge compilation)

This indeed is an interesting development. I tried compiling on Linux and after sorting out a few complaints more and more of them emerged. Basically related to CMake not finding things. Therefore i am guessing things will hopefully improve on Linux in the future. If and when they do i guess we can evaluate if default Raytracing workbench should support CADRays in some way. If it makes sense to pack CADRays in binaries for all supported platforms. This would bring us closer to the goal of having a good rendering capabilities in FreeCAD by default. And for them to be available to non tech-savvy people. Currently this task is still reserved for POV-Ray and tech-savvy people using solutions such as Blender. Render workbench, being external, likely isn't as used and explored as it could be if it would be available by default.

I have it compiled and running on debian. I find the GUI a little confusing.

Likely GPU drivers related?

Hi Thomas, how did you do it? If you can tell me how, I'll have a go on Kubuntu 18.04 64bit later tonight....yeah its evening here now. Do you have to compile occ as well?

I did it by swearing and hacking away on the cmake files. Yes I did compile and install occ as well. Here is a link to a repo with my changes. Use the 'tabuild' branch.

Hi all,
one question:
Did anyone find out how to save the picture without this ugly brownish background? Just a transparent PNG?

Thanks a lot in advance!

Does somebody know how to increase the resolution of shapes in CADRays? My renders have sharp edges. The geometry was created in FreeCAD. I am able to smoothen those lines in FreeCAD by chaning the "Deviation" parameter in the view-tab but I do not know how to do this in CADRays.

It is possible that the transfer from FC to CADRays performs a meshing of its own with its own set of parameters, this is similar to code used in 3D surface milling in the Path WB. In that case the shape parameters used for FC are "useless".

One way to test that is to export your FC model as .stl with different levels of accuracy and check if CADRays reflects (hahaha) that.

Using stl does not work here. Even when setting the deviation to 0,01 mm you can clearly see triangles.
