Brightness proportional object thickness

[Anonymous]

I need to obtain an image of a 3D object with brightness proportional to its thickness along the direction orthogonal to the sheet.

I attach an example in which I obtain artificially what I need.

Can I use some material to obtain it?

Thanks,

Mario

hi scudmario you want to similar results in 3ds max ? i think this is possible with using material shader can you tell what is purpose of this so i can understand it better.

thanks

dear don_3259,

I will try to explain better what I mean.

In what follows I’m refer to the coordinate system indicated on attached figure (fig 3).

In general an image of a 3D object is a projection along z coordinate. For each point (x,y) we have a different level of gray (or colour) and this gives the rapresentation of the 3d object.

On the left image three different color (gray level) are associated to the three faces (A,B and C), this depending on the orientation of the faces in respect to the light source.

On the right image (the image I’m interested on) to each p(x,y) point it is associated a grey level that depends on the object thickness along z. For example along the point p1(x1,y1) the object is thicker than along p2(x2,y2) and for this reason in p1 is brighter than p2. If we move on the edge the object is very thin and the points became darker (for example p3)

The 3ds material I'm looking for is like a x-ray but it doesn't give the results I need.

Thanks,

mario

dear friend as i think its not possible you need max scripting for this to get that results...thanks
