Re: Photo-realistic rendering of FreeCAD models with CADRays
I didn't yet test CADRays but it looks promising. What i am guessing would be nice is for the end user to get good results by default. No renderer i used in the past did that. All of them involve some process where user produces bad results by default and has to invest massive amount of effort in it to finally produce something that looks OK.
Re: Photo-realistic rendering of FreeCAD models with CADRays
Hello.
Played around a little bit with the renderer.
Very easy to use, i really liked what i did see. My thoughts about improvements/wishes:
1.) Import
Best way to transfer data from FreeCAD to CADRays is Step (make sure you are exporting Step AP 214 supporting assemblies) or BREP.
Upon importing, the material of all bodies is linked and you first have to explode the group und unlink the materials.
Either import as exploded or add a radio button for choice as exloded or not on import-dialog.
Material is not linked by default. If I want that i would have ex/im- ported one single object ...
2.) Wanted: documentation on creating new materials and creating new maps (for background)
3.) Wanted: Button for pause rendering (already stated by DeepSOIC)
4.) Wanted: Some sort of "status light" - red: CADRays is working/computing, green: CADRays running idle
5.) Wanted: Right click in 3D-Windows with menu for
* select all visible objects
* unselect all visible objects
6.) Wanted: Right click in tree-view (?) [upper left corner] with possibility to invert selection of objects
7.) Wanted: CAD-Like navigation (Icons or right-click) for choosing Top/Below/Back/Front/Left/Right/Axometric view
8.) Wanted: camera control, definition of viewpoint and looking direction
9.) Think about: adding a tick-box for displaying a watermark/logo in the picture - we just did that with FreeCAD
10.) Think about: In the long run, having three/four small examples (have a look at the Utah teapot and the cornell box) shipped with the software
would be great.

Just another example of CADRays rendering.

Re: Photo-realistic rendering of FreeCAD models with CADRays
Thank you for feedback! It is really important for us in order to prioritise new features.
For now you can use TCL commands: vtop, vbottom, vleft, vright, vfront, vback. Also vfit command will fit view to the scene.r-frank wrote: 7.) Wanted: CAD-Like navigation (Icons or right-click) for choosing Top/Below/Back/Front/Left/Right/Axometric view

When doing some documentation please include (if possible) a short overview of tcl-commands.

Also please take a look at vcamera and vviewparams commands.r-frank wrote: 8.) Wanted: camera control, definition of viewpoint and looking direction
The commands are mostly the same as for OCCT DRAW application: https://www.opencascade.com/doc/occt-7. ... rness.html although not all of them are applicable in CADRays environment.

Any plans on high dynamic range support?
Re: Photo-realistic rendering of FreeCAD models with CADRays
Yes, we plan to add support of exporting rendering results into HDR images (HDR/EXR) in the next version, so it will be possible to perform custom tone mapping in external software. E.g. open source Luminance HDR (http://qtpfsgui.sourceforge.net/) is great choice.DeepSOIC wrote:The ring looks so real, incredible.denisb wrote:Just another example of CADRays rendering.

Re: Photo-realistic rendering of FreeCAD models with CADRays
Hi.
Another thing that came to my mind (haven't tested yet).
Is there a possibilty to append files in CADRays ?
If i am correct, at the Moment the only option is to do all changes (removing/adding of objects) to the assembly in the CAD-System
and then do another export ?
