DF دموی E3 آنچارتد 4 رو بررسی کرده
عنوان: آنچارتد 4 تکنولوژی بازی ها برروی PS4 را به مرحله بعدی ارتقا میدهد
Uncharted 4 goes much further than any PS4 or Xbox One game we've seen in its use of physics, and the layering of world detail with shaders. Opening at the gates of a bustling Madagascan marketplace, what unfolds is unlike any major title seen on console to date. Where the December demo focused on wide spaces, foliage systems, and its more flexible AI, the E3 demo goes to town with object physics applied across the world, as flaunted brilliantly with a jeep chase to 'Sam's tower' at the bottom of the city.
UC4 بیشتر از هر بازی دیگری بر روی Xone و PS4 تکنولوژی بازی سازی را در زمینه ی فیزیک جزییات و شیدرها ارتقا میدهد. قسمت ابتدایی باز شدن درب و نمای ماداگاسکار بهترین چیزی است که تا به حال بر روی کنسولها دیده شده
For Uncharted 4, the sheer speed of the descent shows just how effective Naughty Dog has been in this endeavor. Save for one brief texture flash just as Drake starts moving, no normal maps or geometry suffer from obvious pop-in, and draw distances are impressively broad across the horizon. All of which gives this sequence a surprising level of polish even in this early state, and it's a great example of a PS4 title handling a broad, detailed environment with few streaming issues - even if it does eventually lead to a funneling point.
حرکت جیپ در سراشیبی نشان میدهد که ND تا چه د در این زمینه مهارت دارد. بجز چشمک لحظه ای تکسچر در لحظه ی ابتدایی حرکت جیپ به هیچ عنوان نرمال مپینگ و جئومتری دستخوش ایراد نمیشود. هیچگونه Pop-In در تکسچرها و دراو دسیتنس وجود ندارد. این مقدار از پولیش آن هم در شرایطی که بازی در ابتدای مراحل ابتدایی تکمیل خود بسر میبرد ستودنی است
As a bonus, motion blur is added since the PlayStation Experience demo, kicking in heavily during this chase, with both camera and per-object implementations. It adds a filmic touch sorely missing in the last showing, though a banding trail is also now left behind moving objects - likely an artefact of the temporal component utilized in Naughty Dog's chosen anti-aliasing technique. A recent
post by Timothy Lottes (creator of the widely adopted FXAA algorithm) adds his two cents to this theory. The supreme, clear edge treatment in the December demo is seemingly swapped out in this E3 update, with Lottes suggesting a move to a "viewport-jittered neighborhood-clamped high-feedback temporal AA without MSAA."
Overall, it's a slight step back for Uncharted 4's image quality since the last demo, but the results are still ahead of most PS4 titles today. As a sign of future releases, it also suggests a native 1080p is still very much viable for PS4 releases pushing the envelope with a huge world, though developers are seemingly still keen to top this off with a post-process method of AA - and all the caveats that brings to absolute clarity.
بعلاوه نسبت به نمایش PSX اضافه شدن تکنیک موشن بلور باعث ایجا حس سینماتیک میشود که در نمایش قبلی وجود نداشت. تکنیک AA استفاده شده در بازی نوعی هاله دور برخی از اشیا ایجاد میکند که نشان میدهد AA کمی از نمایشهای قبلی افول داشته ولی به هر حال تکنیک AA استفاده شده از بهترین هایی است که تا به حال در PS4 دیده شده.
Even so, this doesn't diminish the incredible level of detail layered across the city. Despite its broad, branching paths, each area is still richly defined, filled with unique alleyways and courtyards that players may never pass on their first play-through. Most impressive of all is the extensive use of physics across the world - with Drake's own jeep
confirmed to use the Havok engine. Everything from his hair, shirt, and even the vehicle's antenna sway to the wind during the chase; small effects that stack up when applied across the game, lending real a sense of tangibility to the game world.
جزییات بکار رفته در سطح شهر خارق العاده ست. با اینکه شهر بسیار بزرگتر شده و راهها و جاده های بسیاری در بازی وجود دارد سطح جزییات باور نکردنی است. فیزیک بکار رفته در بازی نیز نیز شگفت انگیز است که تماما در سطح محیط بزرگ بازی رخ مینماید. هر چیزی از موهای نیت گرفته تا گرد غبار و حتی آنتن جیپ تحت تاثیر قوانین فیزیک بازی و باد متحمل فشار و بسامد نیرو میشود. که این خود باعث هر چه واقعی تر شدن جهان بازی میگردد.
Drake's early shoot-out also makes a statement of intent for Uncharted 4's use of physics. Every object in the marketplace shatters or bounces off the next item, and players are seemingly never safe taking cover in one spot. With procedural chip damage in place as well, most spots deteriorate dynamically in the face of oncoming gunfire - ripping out chunks of the scenery to leave Drake exposed. It marks a departure from the slower, stealthier gameplay of the PlayStation Experience demo, and players are forced to keep moving to stay alive.
فیزیک در تیر اندازی نیز بسیار در خور تامل است هر چیزی که نیت به آن شلیک میکند تکان میخورد و با محیط اطراف خود تعامل میتماید.
The extent of Uncharted 4's use of physics goes much deeper than you'd expect. One of the more surprising applications of this is one that goes unnoticed; rice bags actually deflate using a mesh distortion system Naughty Dog has in place, as detailed during a recent
Headspace panel with the team. It's an effect also applied on Nathan Drake's face when pressed against the floor during the game's first
blue-hued E3 2014 reveal. In essence, for this demo, it allows each sack to sink as rice leaks out from bullet-holes, where each shot cues a physics-based impact on the bag, while deflation is simulated using mesh distortion.
فیزیک در UC4 از هر چه در ذهن دارید عمیقتر است. کیسه های برنج علی الخصوص پس از سوراخ شدن توسط گلوله از برنج تخلیه شده و سطح ارتفاع آنان کاهش میابد.
Based on a
Game Informer interview, the PS4 entry also aims to do everything in-engine this time, rather than resort to the pre-encoded video cut-scenes used in the previous games. It's a likewise upgrade for Uncharted 4's
lighting system; earlier titles on PS3 baked in lighting properties for each texture, but now it moves to a fully physically-based rendering approach. This means that the use of shaders now determines how light reacts; elements such as wetness, creasing, stitch density, scratches and all forms of weathering now have an impact on surfaces or characters.

It's been a superb few months for those invested in PS4, especially with the arrival of big hits like Bloodborne, Project Cars and an excellent rendition of Batman: Arkham Knight. But along comes Uncharted 4 with a mandate to show what the future holds for this console generation, and in particular Sony's big exclusives. The jungles and cities shown so far are just the tip of the iceberg - only two stops on a globe-trotting tour for both Nathan Drake and Naughty Dog's talented artists. Launching ahead of the gorgeous Horizon Zero Dawn, in
Spring 2016, it feels like the PS4 is about to step up a gear in technical accomplishment, and with Naughty Dog once again at the spearhead of the movement.
چند ماه گذشته برای دارندگان PS4 بسیار عالی بوده از بلاد بورن گرفته تا PC و همچنین ورژن بسیار خوبی از بازی Batman. حال نمایش خارق العاده UC4 نوید بسیار خوبی از دورنمای این نسل از کنسولها بدست میدهد. بنظر میرسد که PS4 به مرحله ی جدیدی از دست آوردهای تکنیکی رسیده است. و ND بار دیگر نوک حمله این حرکت است
