Bump Mapping in Flash

Photo Sharing and Video Hosting at PhotobucketBumpMapping in Flash has been a possibility since Flash 8/AS2 but libraries are showing up in AS3 now.

Here is a collection of the best samples and authors of that code.  ByteArray AS3 BumpMapping and Ralph Hauwert 3D BumpMap + sources.

BumpMapping shows off the power of per pixel operations and how beneficial the addition of per pixel work is when it was added to Flash 8 with the graphics libraries and filters.

BumpMapping is great for simulating 3d depth in textures and can only be used minimally right now in flash due to the per pixel nature of the operation.   It seems more work in this area is maxing out at 256×256 textures/maps.

UnitZero’s BumpMap for AS2 is much faster but the comparison of ByteArray’s experiment is a better comparison since its using the same algorithm ported to AS3.

    […] with AS3 specifically, much of that was due to 3d in flash but also the ability to texture and have bump mapping, toon rendering/cell shading and other neat effects like baked lighting, faked real-time lighting, […]
