Hey Tom YOU are the Printmaster!

Thanks for that useful advice.

You`re doing a great job, giving us the info. I just wanted to say that this topic shouldn`t be about DPI

question:

Is new RC more memory efficient than old beta? i was trying to render over 10mil poly scene in beta. Result: failure. But i manage to do it at the end with /3GB switch in win XP boot.ini . So now i`m rendering around 12mil. on 2GB ram. Without -hd swith of course....
Can RC5 and Final 1.0 be better at memory managment? Did you guys tested with large geometry?did you tested with instances?geometry(important for my current project).

Hello Adam,

thank you, that tool is very helpful.

Orthangonals would be nice, but its not a human or photographic projection.

It would be nice, However.
I have needed rendered orthogonals a number of times.

Hello Peter,

excuse me for that primitive issue with the dpi-question. You are on higher ground and I a´m sorry about wasting your so advanced time.

You`re okay,no need to apologize. You`ve just started a "small topic " in Mvertas topic, which i personaly don`t like. i`m nervous because i`m hungry for new RC info like everybody else....refreshing page avery 2 minutes... (okey, okey,every 1 minute)

Memory management issues, like a lot of engine optimizations, will most likely come together much closer to 1.0. Sounds a little early for a lot in that department, to me...

I am in favor of camera shift and tilt and swing controls. A view camera is the tool of choice for critical architectural and product photography. With the use of shift, tilt, and swing you can control parallel line convergence, location of the horizon line, and the plane of critical focus.

The mathematics are simple (I believe it is under the "Scheimflug Principle" of photography)... but it does bring up a problem.

Vignietting can be a serious issue (especially with wide angle lenses) as you capture your image from the extremes of the image circle (by using shifts and tilts) created by the camera lens on the focal plane (as it is dimmer there..). So a "center-weight" filter would need to be a part of the formulation to compensate.

Perspective control is realized most effectively with view cameras where one can physically shift and tilt the lens and tilt the film plane. Not only do you benefit with control over parallel line convergence (eg. verticals stay vertical) but you gain tremendous control over the plane of critical focus...

The critical focal plane is defined by the geometric relationship between the orientation of the lens with respect to the film plane. One can "tilt" the focal plane to maximize what is in focus in the scene your are photographing. I often made use of these photographic camera controls when I was working with a 4x5 view camera.

This benefit may be moot as long as the Maxwell camera does not suffer from diffraction errors created by the small size of the camera aperture when "stopping down" a lens. If the errors occur, then the image will get "soft" as you increase the f-number of the lens. But if diffraction errors are not a problem, well, good deal.

This approach of maximized detail was well expressed by the "f64 School" of photography (Adams, Bullock, Weston...)and the 4x5 and 8x10 view cameras were the tools of choice and the controls of the view camera were maximized (see Ansel Adam's series on Photography... the View Camera volume).

I would love to see the data for the Maxwell camera lens system. If physical correctness has been modelled (and diffraction camera errors are a part of the render) then we really need to know about it and not make a potential mistake (such as using f22 with a 12mm lens) in setting the camera parameters.

Hello Peter

you are welcome, I am curious too about some news and I started this little question that now has a lot of posts. For me this is a very good sign, how active and helpful this maxwell-communiuty is. Everybody wants to share his experiences and knowledge. This is great and I think none has the right to decide about what the people should speak or not.

You dont need to read the posts, that are not of your interest. Have some patience with others, who need (different) answers too.

Regards
Roman

Hello, Romans
I'm just another user and not NL crew but I think Maxwell will not work with 2-point perspectives nor orthogonal views.
It's just not possible as it's not possible with a camera on real world. That's the simple Maxwell's phillosophy: expect real-life realism AND limitations.
You can make some hand-made correction with photoshop or similar software.

Actually, there is a type of camera that professional photographers use for architectural purposes because it can create a two point perspective.
Don't know what it is called, but it would be nice if NL could recreate it electronically

It's called technical camera; that's what my picture shows. Very old technology, but still usefull for architecture.

The dpi question bothers me. Romans got me all confused. I keep on rendering with different dpi settings to see what's fastest. Early test show that the optimum must be between 623 and 841 dpi.

i just tried 841, it works great for interiors, not sure how it handles sun/sky though.

[Olivier Cugniet]

i have better results with 839

Hey guys.. the post about DPI stuff being useful, but not really part of this thread is a valid one. Why don't you start one, and I'll see if the relevant parts of this thread are moved so we have 2 useful threads and not 1 muddled one.

Hello Mike,

good Idea -but the camera topic is worth a own topic too- dont you think so - I think the last post from mrcharles is very interesting.

Regards Roman

I will try to start the dpi-topic and then you can clean this one up.

[mrcharles]

moved to new topic...
