Hi gentlemen, I am using ToPixmap(...) to generate a nice image from a ray tracing view, but there is only one call to Redraw() in ToPixmap() so my image is 'not finished' as it requires many more passes...

I am thinking to create a new class that inherits from V3d_View and override the redraw function to redraw n times in place of one time but I am not sure it is the best solution ?

For the future OCC version maybe adding a redraw count parameter to V3d_ImageDumpOptions ?

Can you please give me some advices?

Thanks.
Best regards.
Jerome.

You may call Redraw() on your own before making an image dump. If image dump parameters are the same as viewer parameters - you'll get accumulated PathTracing results.

Hi gkv and thanks for your answer. I tried but it is not working as ToPixmap() is switching to another framebuffer for offscreen rendering, this is why I thougth to a more complex way.
