Anim8or v0.98 Discussion Forum / Re: Really wierd render bug
« on: March 27, 2008, 06:27:17 pm »
Heh, heh.  There are a bunch of canned images that I built into Anim8or when I was first working on the ray tracer.  They are supposed to be disabled in release builds but apparently it didn't happen.

To render these tests on your computer, click the Options->Debug->DebuA command.  Each time you do that it will cycle to the next build image.  (You need to do a render to see it, of course.)  You will need to exit Anim8or and restart it to get back to normal.

These tests are old.  They might not work and don't cover every material.   But you might have fun looking at them :-)

I think you misunderstand most of what is happening.  I will try to clarify:

Turning off render preview will not have much effect on the timing for well written graphics drivers.  That's why it's on by default.   However some drivers are VERY slow at copying raw pixel bits to the screen using OpenGL - particular some low end, integrated grahics drivers - so I added the ability to turn it off.  You SHOULDN'T see much difference on NVidia cards :-)

If your computer DOES speed up a lot when you disable render preview, then you have a BAD driver.

The reason that Anim8or seems to lock up during a render (it doesn't really - it's just fully busy doing the render.  It ignors all the thousands of Windows messages it gets per second because some drivers are TERRIBLE at this and slow down horribly even they aren't doing anything - thay just are inefficient - So I ignore almost all Windows messages when rendering.  You should still be able to ESC out of the render.  Anim8or is not frozen by any means -- it's just ignoring you :))

You should NOT see much of a speedup changing the priority.  Anim8or will normaly get 99% of the CPU time.  In fact I am thinking of lowering the priority so other Windows tasks won't get starved for CPU cysles.  Windows isn't a very good OS at switching between tasks.  MACs, for example, are much, much better at it.

Your graphics card is a very good one for Anim8or.  I have an 8600 on one of my computers at work and it runs Anim8or quite nicely.

Hope this helps clarify a few things (to you and others).

Flametiger74 - Please post this kind of thing to a new topic.  This thread simply anounces that v0.97 is available.  It is not for bug reports.  (What graphics card do you have?  THis is most certainly a driver problem, possible a badly designed driver.  That's exctly why I added the ability to turn off renders.)

hihisilver - I need an example .an8 project.  I can't fix it without one.  It looks like a sampling problem.

csf - What OS and graphics card do you have?  They upgrading your graphics driver.  I open and close dozens of projects and do all kinds of rendering without crashes.  I think you are hitting a problem with some other part of your system besides Anim8or.

Tanzim - That is a well documented problem with volume shadows in the scanline renderer.  Use the ray traced shadows options to fix it.

As I understand it, CobraSpectre's bug report is about the new ART Ray tracer (which is the only one that supports 4xaa.)

OK then I have an aliasing problem with the sampler at 4x.  I never got your email however.

The ART ray tracer does not match the scanline renderer exactly and never will.  It is based on a more accurate physical model of light that the scanline renderer, which takes a lot of shortcuts and adds it's own rules.  For example a local light's min and max radius are a hack, not on how real light works, and aren't supported by the ray tracer.
Depth and alpha channel aren't doen yet so I'll probably disable those until they work.

The volume shadow bug with the horizontal lines is know (this is with the scanline renderer, right?  It's not clear which renderer you are talking about on some of these bugs).  You need to use ray traced shadows for these cases.

Wow, a weak power supply!  That's a hard thing to diagnose.  Good job, Tanzim and Roygee.

Yes, that's a bug.  The scanline renderer's shadwos don't work on the ground grid.  I'll fix it.

Roygee - it might help to look at the attributes in the examples for each material type.

Good idea.  I haven't done that yet because I'd need to do some restructuring of the code to support multi-threaded renderenig.  Otherwise Anim8or would stall while the images were being updated each time you made a minor change.  This is even more true with the ray tracer for especially transparent materals. I thought about adding a "View Material" button you could click to do the render but that seems kind of clunky.

I agree and would have something like that already except that it takes a bit of time to write.  Also since I plan on adding mode ray traced materials it would take more effort to keep updating all that dialog code.  If I wait until the features are more stable I'll have a better idea what to do.  (Plus I wanted to get the ray tracer out for feedback instead of waiting until it was "finished".)

I also want to write a material manager to allow you to move materials between objects, projects, whatever.

That looks like a bug.  If you can reproduce it with a simpler example can you send it to me?  (Or even the full project but that's harder to debug :))

Can you e-mail me the project or a simpler example if you have one?  I don't need the textures or anything.

Yes, I'll be adding diffuse textures to glossyreflection, as well as bumpmaps and probebly a couple of others.  Its a lot of code to write and test for all these cases so it may take a while.  I wanted to get something out for people to play with instead of waiting until it was all done :-)
