Bend UV Based on Bump Map ?
Bend UV Based on Bump Map ?
I'm in need of a way to bend UV texture based on a bump map using factory nodes ?

Both of you: relax!
Don't let this get out of hand.
NNois has a point though,
more info seems needed...

That's probably the parallax mapping effect. I used to think this would be simple to recreate in the render tree, but then found out it isn't that simple .. IIRC, the tricky part was finding the right matching vector in the UVs from a vector on the mesh.

Parallax effect is exactly what I need, urgently. I tried to create one using softimage factory nodes, I was unsuccessful
RRay could figure out what I needed, to most others I speak Klingon, or rather maybe they only understand Klingon.

in the end it doesn't make much of a difference ... basic ingredients to parallax mapping would probably be the EditUV node, a tangent map and a pregenerated texture with info on how the uv's are oriented on each point on the mesh, as an offset to the tangent map.Falam wrote:Parallax effect is exactly what I need, urgently.

I had to stop working on that because it got too complicated for me...

RRay - What order should things go ? I will probably be using parallax mapping alot, now and in the future ! If something could get started it would be superb.

Scroll down and download the parallax plugin from benR. See if this old shader work for you.
Cheers!

I'm ahead of you, I tried the shader it crashed my shader tree. I need the manual method as I'm using a Beta shader and factory nodes most likely will work, I could be wrong, I don't think I will beDaniel Brassard wrote:http://www.shaders.moederogall.com/

Re: Bend UV Based on Bump Map ?
Then use RenderMap to create a depth map.
Depth Maps, also called height maps, are grayscale representations of the height of every point on an object's surface. Depth maps are often used by game developers to create a more realistic bump-mapping effect called parallax mapping, which simulates the correct displacement you perceive on an object's surface, based on the camera's point of view.

Interesting ! I hope it deforms the UV texture map.Daniel Brassard wrote:Depth map visualization using the rendertree from P Diary (Japanese) at http://p-diary-tera256.blogspot.ca/2011 ... -tips.html
