max power 21 Posted December 20, 2009 Quote Rebel;1519313']I believe if the actual game system - or engine - is not supporting radical changes within it' date=' its not good in its basics.[/quote']Just like if a car doesn't support radical changes, it's not a good car. I think that a good engine is one that does what it is designed to do. This one does what it's designed to do fantastically well. I refute your supposition by saying that this game is the best in its class and nothing else really comes close- even imitators fall short. Therefore, the engine is great. SFJackBauer said: And what gives you power to be a spokersperson of BIS or put down ideas of forum members? Oh, Jack Bauer to the rescue again. This time it took more than 24 hours though... and I think maybe your intelligence team may have failed you this time. What I was saying was 'I wouldn't count on it for these reasons'. Where was I putting down the ideas of others? I think it's a great idea, I was just reacting to the often thrown around phrase 'it should not be that difficult'. I can think of many reasons why it would be difficult, being a mod developer. Quote The old tale says, if you dont have anything to add to the thread, then dont post. So now you're putting down my ideas and telling me what to post and what not to? Seems like a hypocrisy problem. You might want to check in on that. Quote I could use your argument and say "why they motion-captured human movement just for the sake of appearing real, all we need is a gun and bullets". Or "why they motion-captured some guy dancing and put into the game as a hidden animation"? Motion-capture equipment (which BIS own), and actors to perform cost money and time, doesn't? Its because its technology, and sometimes breakthrough in technology are made because investments in things seemingly futile and unnecessary. I think this incredulous analogy maybe the fault of some incomplete or nonexisting understanding of the issues on your part. Having some people dance in front of the mocap cameras is useful to calibrate and shake-down the equipment. Mocap computers have trouble figuring out what's happening when you have two arms crossing, say. To solve this, some mocap systems have balls shaded in a gradient so the computer knows the orientation of the balls in 3d space, and can better distinguish what's going on between the right and left arms, in this example. I can think of no better test than having someone perform complex movements like dancing in front of a camera, spinning and gesturing in all manner of speeds and angles, and no better way to make a calibration experiment fun than capturing dancing. Quote What the OP is proposing may be low priority in the grand-scheme of things, but who decides is BI, not you or me. Inverse-kinematics has been out there for long time, if they want to incorporate into their engine is their decision. Again, my friend, if you read and comprehend, I wasn't arguing against the idea- just the assumption that 'it should not be difficult'. There is no reason to believe this. On the basis of lack of information about the complexity of the task alone, this is a faulty assumption. Quote From Wikipedia: Inverse kinematics is a tool utilized frequently by 3D artists. It is often easier for an artist to express the desired spatial appearance rather than manipulate joint angles directly. For example, inverse kinematics allows an artist to move the hand of a 3D human model to a desired position and orientation and have an algorithm select the proper angles of the wrist, elbow, and shoulder joints. For example, when one wants to reach for a door handle, their brain must make the necessary calculations to position his limbs and torso such that the hand locates near the door. The main objective is to move the hand but the many complex articulations of several joints must occur to get the hand to the desired location. Similarly with many technological applications, inverse kinematic mathematical calculations must be performed to articulate limbs in the correct ways to meet desired goals. One example where inverse kinematic calculations are often essential is robotics, where an operator wants to position a tool using a robot arm but certainly doesn't want to manipulate each robot joint individually. Other applications include computer animation where animators may want to operate a computer generated character, but find it impossibly difficult to animate individual joints. The solution is to model the virtual joints of the puppet and allow the animator to move the hands, feet and torso, and the computer automatically generates the required limb positions to accomplish this using inverse kinematics. Key to the successful implementation of inverse kinematics is animation within constraints: computer characters' limbs must behave within reasonable anthropomorphic limits. Similarly, robotic devices have physical constraints such as the environment they operate in, the limitations of the articulations their joints are capable of, and the finite physical loads and speeds at which they are able to operate. What an excellent example of a quote that has nothing to do with what we are talking about and displays a complete lack of understanding of the issues. Inverse kinematics is a way of animating. It is opposed to forward kinematics. Forward kinematics solves positions based on transformation information over time. Inverse kinematics solves transformations based on position information over time. This has absolutely nothing to do with what we are talking about. Share this post Link to post Share on other sites
CarlGustaffa 4 Posted December 21, 2009 I vote against it, due to cost of implementing it. Arma uses prerecorded animation sequences to do the work, which is why they are hard (or even impossible) to blend. IK/FK methods has to be implemented, and that's the massive cost. Even with prerecorded animations, some looks completely off sometimes, like insanely stretched arms. With some background in 3D apps/animation, it doesn't take me much effort to see all the things that could go wrong if IK/FK was implemented in this fashion. Personally, by the looks of those horrid animations, it could actually look like some IK simulations was going, because there are no way a human body could obtain the proportions they take. With difference in heights, expect a lot more problems of the type where you play a force recon officer trying to shoot an M136 (using current beta, haven't tested in vanilla 1.04). Having women rescuees being able to sit properly in rescue vehicles matters a lot more to me than varying heights and BMI. I'm not really against it, until I start seeing all the potential problems coming from it. Share this post Link to post Share on other sites

You can not change the height of characters because the whole system turns onto its head, and if you create a fighter - just like the one called: F16 Fighting Falcon - you cannot place the pilot in the cockpit decently because of those boundaries (Not sure if you played with it, from the pilot view you see the hand of the pilot hanging freely because the flightstick was located somewhere else, such a predefined system).

With scaled troops, we're talking about new skeletons, then checking to make sure the all of the rtms are still proper with the new sizes (which they won't be), then making all the new rtms for everything that needs it. It also means selectively rescaling the men but not their equipment for all LODs where the equipment is present. For a company, that's dollars and cents.

Again, quoting secondlife where there are avatars of ALL shapes and sizes and somehow, weapon positioning looks ok because the player get to align and adjust the positioning ingame.... if this has been possible in secondlife for the past 5 years (or 6 years) I think its possible for BIS as well. :) It's far from the same. All the weapons would need to be scaled down in ARMA 2 to fit the smaller soldiers. And weapons just don't change size based on the person holding them in real life.

One thing is, based on his experience, stating that it would be difficult to implement. He made this point once. But other thing is repeating it several times, along the way offending members opinions. That I see as unnecessary. And to top it, that is even after someone pointed out that the suggestion requested actually EXISTS in VBS 2: ceeeb said: BI's VBS2 has a setHeight & setBMI command, so it would be possible within ArmA 2.

sgt_flyer 0 Posted December 23, 2009 the 'vehicle' bone system since arma 1 is totally and really easily scalable (i don't speak about rotation angles, those are not affected by scale) but the translations did scale. the translations unit was not in meter or any other unit, the translation unit for each translations was based on the distance between the two points of the axis used for the translation. (when you give a translation distance of 3 for example, the object will translate by 3 times the distance between the two points of it's axis.) this allowed to make a full rescale of the models without having to change anything to the animations. if they used this just for the vehicles, we can imagine they used something similar for the complex skeletons. (it would be a pain in the ass making a skeleton, the anims for it, and see their skeleton too small for the object it has to animate, and having to redo all anims.)

I see someone putting down ideas from others and talking seemingly "in behalf" of BIS. On the quotes: 1. That's my honest appraisal of the situation. It's a pessimistic outlook but it's a realistic one, I think. Perhaps I should hold TOPs hand and stroke his hair and tell him that his suggestion is sure to be put in the game? We could have an amazingly satisfying cuddle- he could feel safe and warm. We could watch some straight-to-dvd disney movie until he falls asleep... 2. To appeal to some other, unknown, outer influence is a bit... fallacious. Especially if it's substantiating the supposition that 'it shouldn't be hard'. 3.

The inevitable conclusion is that it's a difficult thing, from where I'm standing, however. Quote List which ideas different from the one the OP posted you added to the thread, besides non-constructive criticism. How is spreading the 'it should be easy' misconception constructive? All it does is further perpetuate the myth that programming is some magic art where all things are possible in a short time for little or no effort.

I quite like the suggestion, I just don't think 'it should be easy'. Maybe the way BIS has their software set up, it's a matter of flicking a switch and suddenly all things are possible. There is no reason to believe this, though. No rational person with an iota of experience would come to that conclusion. On the subject of mocap, despite the fact I've given your argument a lot of charity and time thinking about it, I still can't really see how it's appropriate. Animation isn't unimportant, and neither is debugging technology. In a real time game, movement over time is pretty much the foundation of the experience.

If the devs read the thread in it's entirety, it would probably be out of either morbid curiosity or to get more information about the suggestion.

Is citing pithy sounding quotes to say that you also consider yourself an intelligent and well informed person, and that I should describe you as such in order to ingratiate myself to you? This is because I obviously place a high value on pathos and rhetoric, right? :p I'm not attempting to form a long standing relationship, here. Regarding the VBS images hotlinked by ceeeb, quoted by jackbauer: No one said it was impossible. I said it was not easy. Listen here. In updating the renderer, BIS made the ArmA 1 grass layer incompatible with their technology, and it took that 4 patch versions to bring it back. VBS is based on a technology that shares a lot in common with ArmA 1, kind of like how dolphins and porpoises share a common ancestor. They have ported VBS technology in the past, but does that mean it was a simple matter? I'm not so sure. BIS devs have commented on the past that while they have access to the technology and procuring it is a simple matter, implementing it is not always a snap of the fingers. Because some VBS version has it does not mean that it is effortlessly ported into ArmA 2, or visa versa. Furthermore, if ArmA 1 technology isn't compatible with ArmA 2, there is no reason to think that anything in VBS is necessarily compatible. Share this post Link to post Share on other sites
