Making a low poly lego brick

| Hello, I've got myself a relatively low poly lego brick (err hem 13400 faces). This 'not so low poly brick is causing some performance issues when I load say, 10 of them in my physics engine. I am attempting to reduce the poly count within Wings, does anyone have any other suggestions for reducing the poly count ? |
| ||
| You don't have to reduce poly, just model a cube at the same size, attach your brick to it via parenting, set it's alpha to zero and use it as a physics object. Haven't tried it myself but it's what you do for fast collision. |

| thanks mortis will investigate. I was having bother with the 'space' around my lego bricks' being not quite enough in one axis and too much in another just before my computer crashed. Gotta do other stuff now.... swimming then archery. Will have another stab with my bouncy lego bricks tonight. I'm driving a car through them... eventually. |

| Why on earth don't you just use an elongated cube with a simple brick texture on it????? You just need a texture of the little dot thing on top, perhaps 64x64 or 128x128, then map the rest of it to a single pixel so it comes out as a block of one colour. Even if you modelled the little dots with, for example, an 8-sided cylinder, you should end up with a brick with only a couple of hundred polys, not 13000!!! |

| I've got myself a relatively low poly lego brick (err hem 13400 faces) O_OCan you show a pic? I have to see that! |
| ||
| as GfK said..i would REALLY like to see where went 13400 faces for..cube.. |
| ||
| I'm guessing he's fully modeled the brick i.e. including all the peg thingies that stick out the top, as well as the holes underneath. Maybe? |
| ||
| Yes, but still... 13400 faces? Those must be silky smooth holes and pegs. |
| ||
| @big10p yep you're right the model has the hole underneath with space just like a real lego brick. @ the lego on top of each raised cylinder. In fact it was this which I moved into B3d with ultimate unwrap. (;-). Of to get a treadmill we 'won' of ebay. Chow. Heres where I sourced the brick from: http://www.the3dstudio.com/product_details.aspx?id_product=43398 |
| ||
| Woah, is the Lego logo even modeled? That would explain the face count. :) |
| ||
| I would believe someone if they told me they just took some pictures of some real legos and put them on there. |
| ||
| http://www.the3dstudio.com/product_details.aspx?id_product=24220 that one above has got 357000 polygons, I used one of these associated with a HNC in BIT last year. I wonder if the college could just get the software to program a 3d version of the lego..... virtualisation taken a step too far ? |
| ||
| I would have to buy it myself to make sure they didn't just take a picture of the real thing! I don't see how they do it? |
| ||
| There's a free cad program called l-cad and there's a renderer called l-draw that has a all the parts models. |
| ||
| thanks craig, will have a look. I re-modelled the image in UU3D and Wings, lot less polys but left me with an annoying 'spear' that could not be deleted in Wings. |
| ||
 Did that once to help someone with their coursework :D the legs are hollow with proper holes, etc. like the real thing... and has the text as polygons too... whole thing is less polygons that those bricks... My point being it should be possible to make those bricks in a LOT less polygons and still look almost if not as good... also if your not too picky you could use a bump map for the lego text and save on a ton of polygons... That aside you don't want to be using the full detail model for collision detection ever. |
