how to make terrain?

Hi good morning cg pinoy!
Just want to ask lang po sana kung paano po gumawa ng terrain sa autocad and 3d max? Our site is in contour type, the problem is that we're very near in the proposed 3rd runway of DMIA. So we decided to make a 3D presentation for the approval of the permit we are requesting. Please help po..........

hi welcome to this forum...
i will try to answer your inqury... i don't usually use autocad so i guess i can't answer you directly but doing terrain in 3ds we have plenty and many ways how to do it.... note these are merely ideas im giving you and not a direct output to your presentation and may later adjust things by yourself... so lets get startin'....


1- you may want to build it in matte alpha.... startup paint program (photshop, corel etc..) and start painting some blotches see pic1 below

make sure blotch edges are soft and in feathered....
then start 3ds program and apply it in bump map nor in displacement material editor and adjust bumpiness to your likes


2- you can also modelled it by hand, draw a plane from the geometry slot with enough and high segment values say 40x40 and more maybe.... convert it to polys, select the vertices (press keyboard 1) and then activate the soft selection... since vertices are still selected start pushing and pulling the vertices... you can adjust the falloff, pinch & bubble parameter to your liking.... see pic

3- using perlin marble in the displacement material editor see image

hope i made some help...
pm me for further inquiries

godbless

i will give terrailn file...madmi ako nun...cge pm lng..terrain file with materials n din..sana mktulong ako sayo...

if you have a contour data in *.dwg, you can simply import that in 3ds Max and produce a terrain:

- Select spline contour data > create panel > geometry > compound objects > object type rollout > TERRAIN



.

Thanks po!

actually, to be more accurate.. u can import ur terrain details from autocad to 3dmax.. then just elevate or more up the contour lines based on its elevations, after u have established the elevations, just click "terrain" under "compound objects".. u can also find how it is done inside 3dmax reference under "help" menu..

or if u want instant terrain, you can use VUE 6, with a plug-in Vue xstream for 3Dmax, super doper powerful.
