They are quite heavy on the maths though so I might start with something simpler as you have done here. I much prefer shader code to maths so thanks for that :-)Anonymoushttps://www.blogger.com/profile/07703067646030334728noreply@blogger.comtag:blogger.com,1999:blog-2324674317366173964.post-13766903429942852902014-03-01T12:22:25.141-08:002014-03-01T12:22:25.141-08:00David, thank you for the links, I didnt know them ...David, thank you for the links, I didnt know them yet. <br />The formula above is the result of investigating the camera tangent-space vectors and developing the most simple solution for the problem.<br />I believe its even possible to use the geometry shader to compute the normlized dFdx(tex_uv) and dFdy(tex_uv), which might increase the render performance further, since the entire term (tdx.x*tex_tan+tdx.y*tex_cotan) can be removed from the fragment shader.Spacerathttps://www.blogger.com/profile/01007372171107150216noreply@blogger.comtag:blogger.com,1999:blog-2324674317366173964.post-17982947957362876742014-03-01T11:45:28.172-08:002014-03-01T11:45:28.172-08:00Very interesting, is this based on the work of Mor...Very interesting, is this based on the work of Morten Mikkelson or Christian Schüler?<br /><br />http://mmikkelsen3d.blogspot.nl/<br />http://www.thetenthplanet.de/archives/1180Anonymoushttps://www.blogger.com/profile/07703067646030334728noreply@blogger.com
