View Full Version : Bump on edges.

I frequently am disappointed with the way "bump" cannot be seen on the edges of a 3D object like a sphere. Yes, It's because it's a surface treatment only and has nothing to do with the geometry. But I'd like to see a fake edge which mimics the look of a realy geometric displacement at the point the surface is at 90 degrees to the camera, in the same way fresnal works. It would provide a cheaper alternative to the costly render times of surface displacement.

Adaptive sub pixel/ micro displacement ;) . I'm sure, we'll see it in v8 'cos it's already been asked for so many times.

I am not sure we will see that in LW 8.0
The problem is that this needs a lot of memory in renderers that are no Scan- line- renderers.
LW is not a Scanline- renderer.
What could be done easily (and I realyl hop that this is done) would be to distort the shadows that are cast onto bump- mapped polygons. Something that is strangely enough stil missing in LW, even though this could be done easily (would cost little to no renderperformance too).

I'm sure since it only takes one simple line of code.

Heh, sounds like my boss.. Either that, or it's only a two minute job! :p

That is what I was thinking when I saw

that's still displacement, not fake bump stuff.
