displacement tests thread
guys - can anybody pls answer my previous question? > "is this similar to use of disp mod in blender (BW disp map + hi poly mesh)? is this more memorywise than blender-like technique?" and could u post ur disp maps along with renders? and what is approximate polycount of this subdivided sphere?
cheers

@pxl666 : Well, I'm not expert, but I think the result should be more or less the same. The only difference is that indigo performs some adaptative subdivision, meaning the mesh is only subdivided where it's needed--> smaller mesh (though the same kind of modifier for blender is in development).
In the end, I bet it will be much more practical to use indigo's displacement rather then applying tons of modifiers in blender.
The spheres I rendered have approx. 35000 faces, and are subdivided 3 times.

Nothing fancy, Dr Bouvier.
I just grabbed the diffuse map from CGtextures and used a greyscale version for displacement. It's not even tileable. But there you go, with some work maybe you could do something useful with it:
Adding an Arroway texture attempt. Now we can render these beautiful stone walls!
EDIT: Oops, sorry about the huge images. Here they are properly packed.

hey guys
i tried some displacement a while ago, harrasing some dudes on chatzilla for help. still, my results were... crap. i was wondering if anyone could write a tut on displacement in blender and blendigo. if you cant be bothered then i spose dont worry, but i think it would be great for the wiki.
great work guys

@matsa : displacement doesn't work in blendigo (yet), it's one of the kick-ass hot feature of the latest indigo build. So you have to edit your file manually.
you have to edit two things :
* first, choose the mesh you want to displace, and add this code just before the <embeded> tag :
* then find the material used by the mesh, and add this code, somewhere between the <phong> or <diffuse> tag (change texture.jpg with your own texture) :

Code: Select all
<normal_smoothing>false</normal_smoothing>
<max_num_subdivisions>3</max_num_subdivisions>
<subdivide_pixel_threshold>0.0</subdivide_pixel_threshold>
<subdivide_curvature_threshold>0.1</subdivide_curvature_threshold>
<subdivision_smoothing>true</subdivision_smoothing>
Code: Select all
<displacement_map>
<uv_set>uv</uv_set>
<path>texture.jpg</path>
<exponent>2.2</exponent>
<b>0.035</b>
</displacement_map>
