virgin you in the mode is a full 3d jet in this release was supporting a set of five finger little effects we're not supporting through the arbitrary programmable makers in this version so these five affects your color the technique to render window to create different practical effects plus right back to class what's under acceleration 3d rendering a 3d model basic effect is familiar from the remix next video versions we've had this class for a while so we've done a lot of work to optimize it for the phone it suppose anywhere from zero to three directional lights implemented as Dundon blend long training model if optionally supports a texture what's home and it supports a vertex coloring and there are different performance implications to which of these things you turn on you look at this table you'll see that without any lighting enabled it's really cheap final instructions and their verdicts one instruction per pixel running on the GPU if you turn on dress in one place that's a valuation third vertex the vertex crossed over 58 the pixel fast day is very cheap if you can on the three life that I'm even Warcraft religiously there's only one lights three lights that included two lights we don't have a special adjust to life if you tell on Exile lighting which in performance tax write down so we had excellent performance go to weigh down the pixel cost jumps up to 50 instructions I can show you that in action in this demo unit session soon and after this tank isn't way that's really quite a high quality very digital model let's imagine a little bit at the moment that using the three vertex white smooth if i change that to be pixel ice the fulness hasn't really changed because it's quite small on the screen so it's not covering very many pixels but now we're going then you'll see that the primary of the way down pixels and we fix the lights of vegas that's not really been run too fast change it again as too much completely off just one life that's with three lights so amazing effect the capital things lightly using things that is for all scream all scream things that you fix the lighting and expect that to run fast then the model with the table here i'm showing you is turning on a texture doesn't affect the performance too much turning on a bowl ads for its ruggedness for the better shader that doesn't mean don't you smile this time committed it could be a great thing but don't turn 5 on all the time you don't need your texture effect this time this is really good effect of using on the phone the thing about the mobile otherwise it's not an xbox 360 it's a nice GPU if it's look our compared to what you probably used to seeing in a pc or any console and the way to get rid lookin graphics other chips habits that's how tall is to pre-compute if you use the behind you don't through the runtime so this guy's into two textures with two different sets of technical elements in blended them together using a modulator to net multiplied to them and then doubles so that means you can / brighten the textures contender colors brighter than mid-grade the end of all will end up Roger the first texture was so this is useful for lighthouse it's useful potential textures mr. Mohan here rotate around its a simple 3d scenes lost but under life that's the base texture very uninteresting attend the texture offline apart and you see the light not texture free computer an independent different areas of color in tins and shadows using blowing chase if i multiply them together in perfect lighting the great thing about very much in resume is appreciative ability it's just seven inscriptions of the vertex and thick subscriptions but nixle and you can do pass fancy legends you want a fiercely you can preview this impacts of miami multi package so you can do registered lighting make thousands of lights interesting and it is still enormous renderman will show you the alchemist alpha test is the rejecting pictures based on their alpha value so we'll test me all the pixel is coming in and disabled with that and special rights if the offer is less than or greater than or equal to that's quite ugly this is really useful to billboard a million hospice when you can take a complex 3d shape tourism to a render target and then brother Brendan onto the screen as if it was in the 3d world using on the desk associate occasional things around of the tests on Windows Azure often consider the performance optimization it's only fun just just telling you not to bother rendering pixels that absolutely that's not the case of info this is where our blending it's free can you stop attending one more time I'll everything that you want on securing at all actually this GPU architecture throughout the tech actual cost you a few extra instructions compared to not doing it what I'm going to this demo this is shown in technical depositors December an awful lot attacks can spin around them good friends what i'm doing here is i'm only have to bring one time the dog and the screen in real time this is a really cheap tempting for a lot of games and you want to be crouching with 1000 different people just dropped eligible to bring the targets and scatter cops all around the world it's also greatly games where the cover isn't changing too much because you can do things like butter public buildings bunch of trees and things but in my auntie escape i'm going to draw the comm building at all it's learning to read the targets and then as long as the camera stays in the same place every frame Agnes brother Brendan soccer to the screen from my player characters around and not to rerender the building from scratch so you can get the Elizabeth Woodville complex geometry than your actual memory skinny event it's very simple it has the same lighting model that's basically it was wonderfully right with the same performance characteristics one- faster than three lights pixel lines probably operational deployments mr. this vertex hitting on the GPU it supports up to 72 votes and it supports like a 12 or four way to the vertex and you can see from this data that one way to the vertex and fastest to way to the vertex and spend instructions with legislature and going up to four way to the vertex s 13 emotions just polish huge difference if you want bradenton characters will wait so obviously good that there is a performance benefit to using fewer finally this is the environment affect disposed to making things with the chain it has a couple of different moves what is this he has an induced texture and then it's samples of you get environment of the top of that you can I do remember to visit mobile apps on the fly dynamic reflections well you can this brief you have an environment that much here's a typical set of what surrounds my scene at the game world it's going to be used for shiny objects it also be used with a specular lighting to simulate very many lights so whatever they i'm going to turn all the environment off so you can see the system static model have a king map that contains this background image rafting trip to scram my object since I just turn up the environment that molarity is just going to turn to turbonegro reflecting surroundings and see if it drops in the spray reflecting in my new fon Fabre of the first 19 if I they're fucked total this chromium everything's absolutely elated I can't end up renault factor what this does is simulated property of light in real life where when light strikes strikes shiny object strikes it and on like this it doesn't really reflect you much but its life sprites comprising angle it comes welcome looks very shiny so if i turn the phone on our club you can see that when you have faces the camera it doesn't effective at all but if it's been there John that if it comes more shiny all the object I can get a very subtle reflection attempt another Paxman turn the end my god you looking at the new tenant specula see the reflective manages the clit licked by a lot of very bright shiny life well that's doing with this controller is taking the other child with you man multiply this color I specified if I draw a little bottles for Brad shapes into the other channel of my team up against all the clutch back to the life of the results through the breeding really cheap Shana that leaves just handled pixel instructions I'm reading something that looks like things live by thinking about 60 specular lights on the same objects
