Smoth shaded lines with interpolated transparency (rays) + textured parallelpiped. I used simple line drawing routine released sometime ago by Pablo Reda. I extend it a bit by adding transparency and color interpolaion. Thanks for your work Pablo

edit1 : add link to screenshot
edit2 : in some resolution appear horizontal line - fix attachment.

Wonderfull

Thanks a lot!

good work!
Thank to you macgub!!

Well done!

I couldn't tell (didn't stare too long), but is the texture mapping perspective correct?

Hey MacGub, I have a lot of all integer algorithms for graphics, but in my forth (r4).
I do some experiment with integer software voxel rendering too and sure continue working in some time in this subject, if you go to this area tell me for pass the ideas or the code

Sorry for delay...
@comrade
It has no perspective correction. Its parallel projection.
@Pablo
Hey! Thanks for your offer. But whats a pity I am not familiar with forth. But I think also running executables are worth to see.. Could you give link to binary???
@all
Good luck

OK It's all nice described at your git repository. Screenshots looks interesting. But voxel method requires many memory... Anyway nice work. Conclusion: r4 is project you work since years. I like your stuborn and conseqence.
