Anyone has any input on what should CoronaCamera look like, what features should it have (aside from the obvious ones), how should it be drawn in viewport, etc?
-
Is focus selection in viewport possible?
-
why should invent a bycicle?
everything is generally invented. just need to make it usefull and easy to customize and understand,
of course it should have f-number. exposure control, shutter speed and ISO and custom white balance.
and in viewport it needs to be showing planes of DOF.
and, yes, some unique and recognizable form of the icon of camera showing in viewport. may be smthng like digital cams
and,yeah, focus selection in viewport could be very useful:)
-
add please DOF, shutter speed, focal distance in mm, clipping, target, bokeh, verticals camera correction...
-
ok, viewport focus it is
why should invent a bycicle?
because if I did not in the first place, I would be still using vray :D
-
BTW if anyone comes with a nice viewport icon, I can implement it ;)
-
Do as in Cinema 4D :)
-
- orthographic, spherical, cylindrical, etc camera modes directly in the cam (which I guess was planned anyways)
- what about stereo cam features? (It's nothing urgent, but worth a note)
- vignetting (some people, not me, actually like that in physical cams)
- lens distortion (same as above)
- about the icon: just make it big enough to actually grab it, those vray boxes suck. Max's standard cam is pretty good, something similar would be fine. Just don't do something totally different just for the sake of being different http://us.123rf.com/400wm/400/400/Cole123RF/Cole123RF0806/Cole123RF080600007/3123109-numbered-film-strip-and-movie-camera-with-lights--vector.jpg (http://us.123rf.com/400wm/400/400/Cole123RF/Cole123RF0806/Cole123RF080600007/3123109-numbered-film-strip-and-movie-camera-with-lights--vector.jpg)

icon - smthing like a top modern cams
to shoot like a pro :D

I would like to be able to see camera target and DOF planes while looking from the camera. For example now with standard max's camera you have to switch to perspective to see some of its helper objects. It's pretty annoying.
Here is a description of camera object from Brazil r/s:
One of the areas of expanded capability is lens projection. Brazil offers specialty mapping with Environ Mapper, Orthographic, and Panorama modes. There is also perspective mapping, the view most 3D apps offer as a traditional camera view.
However, this common type of projection is linear. Real lenses are not linear in short focal lengths but exhibit curvature of field. Brazil offers Spherical projection to emulate this wide angle lens distortion. Spherical projection is represented in the viewport by a blue plane perpendicular to the optical axis of the camera. When the focal length of the lens is changed, the degree of curvature in the spherical plane changes. This is a great interface innovation.
There are also iconic representations of near and far clipping planes, near and far environment effects (such as fog), and depth of field. Any icon can be made visible or invisible in the viewport. One of the more whimsical features offers the user a selection of camera icons shaped like familiar motion picture and video cameras. You can also create and load your own 3D icon.
I think it's pretty much all you need.

One thing I love about Vray 2.0 is that I DON'T need to use Vray camera, and just tick vray exposure at Max Exposure settings. Other camera parameters are in Vray general menu.
Other thing I like (in engine I otherwise dislike) about Maxwell 3dsMax integration is it uses native Max camera and just adds parameters to it within inside.
Please don't add many unique features to otherwise current perfect integration within Max. As things are right now, scenes can be pretty renderer-agnostic if we can keep same cameras between Vray, Corona,etc. Or atleast don't make them requisite. I really hate the idea of using special camera when I simply really like the basic camera or no camera, for quick view-port renders. This was complete disaster before Vray 2.0, as I had to setup camera even for quick test render and that is quite annoying.

very useful would be to have in the camera settings opportunity to choose image size
-

Aspect ratio and crops. Now that would be something...I remember a script that did this in pretty in-flexible way. Would be very cool feature.
-
I'd like
- Exposure on a per camera basis, great for setting up multiply lighting conditions in the same scene.
- Rule of 3rds frames.
http://en.wikipedia.org/wiki/Rule_of_thirds - Vignette
- Glare, lens dirt,
- All the typical ISO, F/Stops, shutter speed, white balance, etc..
-
I miss "image plane" feature (native in Maya) on Max... But i am afraid that this isn´t a "camera feature" lol. ok, i will beg to Autodesk. lol
-
Ok i will say what i would like to have on a 3D Camera as a feature, not thinking about what CORONA camera need to have, just my simples whishes besides ALL the ordinary features listed on C4D Camera and VrayCamera... Not in any order...
- Image Plane option;
- BackPlate size options;
- Visual node (on viewport), as a pickable/animatable (in one local axis) object/element like a Focus Plane with a distance indicator overlayed near it;
- Nodes to control/illustrate Zbuffer near and far;
- StereoControl (The last 3dsmax 2014 Extension already implemented StereoCam Support to Native cameras);
- Embeded Hideable visual features;
- FPS setting on camera. Like in realworld, regardless the timeline settings. (This is like an impossible dream);
- Read Exif from any given image and setup camera/lens to match that Exif. Never saw this on 3D Programs, and maybe it´s easy and useful; (maybe not)
Sure i am not expecting any of those whishes to have on CoronaCamera, since it´s a render engine not a CameraPlugin... Maybe only the Exif thing could be nice to have. :) BTW, Nuke has the capacity to read Exif info, so, maybe the hability to include the camera 3D Exif on the EXR could be something interesting to have too. :)
Just brainstorming here. Don´t punch me.
-
By the way, i always wanted in vraycamera this function: when i have finally made all settings so the result picture is good in exposure, but then i decide to make dof stronger, so i change f-stop number...and, all my settings now is wrong and i need again reconfigure all of them: shutter speed, ISO etc.
So, it would be very cool to have some button, so if this bttn enabled when i enable dof and change f-number - all other settings wil change automatically.
As like we have now in corona, when changing F-stop number for adjusting DOF and this don't affect on overall exposure of the final picture. It is very comfortable

ok, after some research and Juraj_Talcik's post, I've decided to go back to the modifier for regular camera, because it will allow everything I need (I havent noticed before regular cameras have orthographic mode ;))
-
good decision! This will allow us to use instanced modifiers - hurray! :)
-
you can thank 3dsmax API and its inability to do any other projection than single point perspective and ortho ;)
-
"Thank you for your inability to do any other projection than single point perspective and ortho 3dsmax api" :)
Actually, I was aware of this problem (ortho and single point perspective) but nevermind - still enough toys to play with. If you can still do the things suggested here, a modifier is fine - I actually prefer it this way, a lot less clutter and we can still use existing scripts and stuff

And why not add new parameters to a standard camera? As Maxwell, for example.

We would not be able to copy/instance the "information" on other cameras so easily and it's a bit more pain in the ass to clean a scene from corona stuff (missing plugins and blaaerrg.. very pissed by fR's physical camera especially in that issue) if we need to convert and give it to a client or turbosquid etc.
-
Amazing :- ). I didn't even thought of modifier. Instancing info from camera to camera seems like pretty neat thing !
-
With camera modifiers, need always search this modifier and aplying, it is not very convenient!

You can "pin" the top modifiers you use, then you don't need to search for them.
-
and it's pretty easy to write a "make a corona cam" script, for everyone who likes to use hotkeys or likes to do it via the create tab ;) You wouldn't really notice the difference.
-
I have really no idea how to modify existing camera plugins, and it sound waaaay too dangerous and hacky. I just hope they are not replacing original camera plugin DLLs from stdplugs (if they are, they will burn in hell :D)

Camera Item of modo 701 lux

Chromatic Abberation? Don't know how much of a hit this would be render-time wise...
-
Despite I registered just a while ago can I suggest Colormapping by camera ?
-
Excuse me for my poor english...
If is it possible, I vould like lens shift possibility directly in viewport, to simulate an optical bench.
Thank you very much Ondra for everything you do.
-
Please insert sensor size (its called film gate in vray) to emulate medium/large format cameras. Its very important to me.
And I have one interesting idea. In photoshop in cameraraw plugin you can correct geometric distortion/vignietting/abberation by choosing correct lens profile. These profiles are small files which you can download separately from official site.
In corona render it will work in opposite way, you will be able to emulate specific lens characteristic. Would't be so great? :D
-
the film size option is available in global render settings

It would be nice to have it per camera. If you have a scene containing a mix of portrait and landscape shots, you'll need different film gate settings for them.

+10 for image planes a la maya!

good evening
-
Sorry to add a comment so late to this thread (only just started using corona).
If it's not too late I'd like to suggest adding the 'overscan' feature to the camera.
Often I have clients asking to extend the image to the left, right, top, without actually
moving the camera as that would change the perspective.
thanks
Sunny
