Inspired by some of the requests for illumination components, I started to work on a new illumination filter, inspired by the phong reflection model, with a few additions known from the build in surface reflection model.

This one is *alot* faster than my previous "Sphinx Shader", and uses a lightmap instead. This map is then used to illuminate a surface input via a bumpmap. The advantage of the lightmap method is that you can create spotlight like lightning, with full control over the final light directions and properties as these are rendering into the lightmap.

I'm currently tweaking and testing the thing.. so don't expect it to be in soon.

Here are some testrenderings (these can be tiled):

Yet another.. with different settings (same bumpmap)

one more.. this one combines the lightmap with the input image to create a metallic style surface - still needs some tweaking though

will be interesting to look at the guts on this one.

just to point out the idea here... the surface mode is not active here.. its 100% build by components.. this allows us to do more complex illuminations.. which could then be used along with the surface mode smile;)

lifesaver brightness as heightmap, and the image itself as reflection map.. looks a bit weird though

yeah, but i like it. looks like the LF is bulging outwards a bit.

Here's a test render with my Gold Ore filter (uses diffuse, height and metallic maps) - the lifesaver is used as reflection map (not really suitable for this), however there seem to be some saturation errors - still tweaking the illumination combining..

Same filter with higher reflection blur and red ambient light:

----I've been working on that kind of stuff off and on for 6 months or so, but I have no idea what I'm doing ha-ha, so it's slow going, and no one here ever seems to care much about that kind of technique (well, maybe cause I am just not that great at it, but anyways). Making something look almost like a texture/surface filter when it's just a simple filter = way cool, keep at it. smile:)
