Great for games and web content as the mesh will render faster. The color and normal maps putted back on the simplified mesh give it a look nearer of the original. There is only one use of normal map which is very interesting : Create an UV bounded color map and normal map from an high poly mesh (say 15k), then simplify the mesh to 1k vertices. So is anybody else up to the next half of the puzzle ? ov0 I really need to get my box cleaned up so I can do test builds quicker.
Thankyou for thelink I will test it tommorow.
But hey maybe you are working on that in secretĪnd Slow67. Now who do I pesster to get the extraction part created ? As just making the useage is great ! But not being able to make the normal maps it’self is pretty much defeating it’self. And I am glad I finaly have an answer for that little bit of code. I don’t really think it is all that useful in non-realtime rendering as I said before (although renderman uses normalmaps, but not necessarily for bumpmapping), so I don’t really think this will be included in Blender, it is just for those who want to experiment with this themselves. It only allows you to use normalmaps as bumpmaps for rendering, it doesn’t create them, for which you need an external program.ītw, I didn’t see it on the page from the link above, but the ATI ‘NormalMapper’ program actually does create normalmaps from meshes.

Anyway, I just posted a small patch in the committers list for anyone who really wants to try this in Blender:
#Renderman tutorial normal maps code#
That code will just mean it only returns colors, it doesn’t do anything to get the normals from the image. Normal mapping really only became interesting because newer GFX cards can do it in real time. The same technique can be used to create a bump map. You use a blend texture to capture the normal. It is easy enough to create a normal map from high resolution geometry. Personally, I think a bump map is easier for an end user to create/paint etc.
These can generated directly from stucci textures/plugins or derived from the bump map. Internally, the Blender renderer uses normal maps. Normal Map: A RGB image that affects the lighting of a polygon.ĭisplacement Map: A greyscale image that affects the geometry of a polygon.Īll three techniques are used to add more detail to objects.īump/Normal mapping only affects the lighting of a polygon - you can see the illusion from certain angles.ĭisplacement mapping is much more CPU/memory intensive, since there are more polygons to render. It would make Blender evn more high class.īump Map: A greyscale image that affects the lighting of a polygon. Please create the current popular RGB normal maps. And style is in a class of it’s own.Īnyway. But what I do know is that RGB looks much neater and new compaired to the antique greyscale images, as math in it’s true graphical form is very neat to look at. NOTE: I AM most likely wrong about that waveform part. Like energy has color in the amount of power in gives off. I would just guess that the Color of the RGB has a better messure of natures faveforms. Now what the difference between the RGB and the Grey scale as I am not compleately sure. So thus far, yes ! A RGB normal map would be a good feature to have. Now the second use for it would be If it is used on that 3000 faces mesh, this 3000 face mesh would gain even more details that would look like it is around 20,000 faces or more, in fine details. The first thought of a normal map is usealy just to reduce a mesh that is around 3000 faces to 500 faces. The purpose of all of this would be for speed and detail. I see a work flow that entails the displacement mapping during render time would create a UV normal map of the meshes displaced data and bake it to the meshes texture. And that ORB program is only for windows.Īs for the use. And For Linux I have yet to see any either.

Really the only program for OSX is a plug in for the 1,600$ software Lightwave and Maya.

As I for one am on OSX and there are nill zilch nada no Normal mapping programs for OSX that are free or ever low price. Just telling the 3D community the fact Blender now accepts and Creates RGB Normal maps would get even more attention for Blender and it’s cross compatibilty. If it is trivial then I do not see why Blender should not have it. It constantly seems to be confused with displacement mapping.The ORB program does create normalmaps from meshes though. About normal mapping, it really would be trivial to add this to Blender, the question is though if you would see any improvement.
