stevefigueras Posted July 20, 2005 Author Share Posted July 20, 2005 My plan is a bitmap or jpeg of 3000 * 3000 pixel in black and white , white for the street and black for the rest ! It's a city plan and i want that 3dSmax build automatically the street in 2D plane and i want thaht 3dsmax build automatically the buiding with the form they have on th emap ! Thank you sear for your attention and for your answer ! steve figueras Link to comment Share on other sites More sharing options...
ecastillor Posted July 20, 2005 Share Posted July 20, 2005 best bet is to take that bitmap to a tracing program and export it to dwg or dxf, then extrude it, but i wouldnt recommend it, as your bound to lose a lot of detail. better to trace over the bitmap directly from autocad.

stevefigueras Posted July 21, 2005 Author Share Posted July 21, 2005 Ok i will try ! but could me explain with more detail what it is autocad , dwg and dxf ? I'm a newbie sorry ! Thank you very much ! Link to comment Share on other sites More sharing options...

amarkovi Posted July 21, 2005 Share Posted July 21, 2005 you could try using the jpg as a displacement map....make a plane the size of your picture (AxB) ...then put the jpg in the displacement map of a material add the material to the plane, then add a displ aprox modifier and adjust the gizmo....with a little tweaking you should get the buildings to be one height and the streets below them....convert the plane to a patch and them subdivide into smaller segments to get a more precise model Link to comment Share on other sites More sharing options...
stevefigueras Posted July 21, 2005 Author Share Posted July 21, 2005 Thank you for your answer amarkovi but can you explain me with mor detail this?

amarkovi Posted July 22, 2005 Share Posted July 22, 2005 1) you make a plane the size of your jpg 2) you open the material editor and assign your jpg to the displacement map slot 3) then you add a Disp Approx modifier to the plane 4) render and you should get the white areas of your jpg elevated and the black areas should stay at zero elevation you will probably need to adjust the number/size of segments your plane is made of to get a more accurate model either by converting the plane into a patch (select plane, right click mouse, convert to patch) and then make the subdivision greater or by adjusting the number of segments of the plane when you create it......also when you add the Disp Approx modifier the rollout has three options for a small-medium-large mesh, but this will depend on the number of segments the plane is made of I think it would be better, though, to create a real model by using the jpg as a plan and then making boxes the height you need....it will maybe take more time to create but you will have an actual model....using a displacement map is good for landscapes but I'm not sure it would work too well for your case.....actually it all depends on how you plan to use the model later...try it and see what works best for you Link to comment Share on other sites More sharing options...
