did you use a high res normalmap or applied some filtering? tried a couple of different techniques and always ended up with nasty artefacts...
@woei: The normal map and the heightmap are quite low res (256 x 256). The quality depends on the nr of heightmap traces. It's the "Advanced parallax mapping" approach from here:http://developer.download.nvidia.com/SDK/10.5/direct3d/samples.html
ah, tried a couple different sourceshttp://www.gamedev.net/topic/570759-pom-hlsl-glsl/https://www.synapsegaming.com/forums/p/821/3656.aspx
and some more
none super satisfying...
