    Phoronix: Unigine Heaven For Linux Status Update

    Our Russian friends at Unigine Corp, who have their very impressive Unigine Engine that is multi-platform and delivers the best graphics on Linux and have said they like Linux very much, last month released Unigine Heaven. Heaven is the most-impressive tech demo / benchmark yet, but when released in October it only came out for Windows with its DirectX 11 renderer...

    In other words there's no reason not to release it now, since most users won't see the tessellation any way. I also don't get the part about waiting on AMD. If it doesn't run with particular drivers, just blame the drivers if they're at fault. Holding a demo back because of one particular driver seems a bit silly but whatever.

      The problem being, that is the driver for only hardware that supports tessellation. They could as well be waiting for nvidia's hardware to show up.

      I really don't see the problem in releasing the demo without tessellation, and adding it later when the support comes.

        Besides that, for the tessellation functionality you will need DirectX 11 grade hardware (such as AMD's Radeon HD 5000 "Evergreen" series GPUs, like the Radeon HD 5750 and Radeon HD 5770) or NVIDIA's GeForce GT 300 "Fermi" series once released. This hardware isn't exactly widespread at the moment, so most Linux users already will be limited to running the non-tessellated version of Unigine Heaven.
        since when is DirectX running under linux

        or, more specific: why do we (linuxusers) need a DirectX11 graphicchip for OpenGL?

          Because you want to use some of the features defined by DX11 on Linux via OpenGL extensions.

            Will this run on OpenGL 1.5? I'd like to try this on my 4850 using the mesa driver.

              wasn't the tassellation unit present also in DX10.1 parts?

                Yes, but it's a different design, without the hull and domain shaders AFAIK.

                  ah okay...so I've to buy a new graphiccard.

                  whoa...that is the very first time that I buy a new graphiccard because of game and not just because I'm buying a whole new PC, because my old one is either not working anymore or it is given away to parents.

                  cool o_0

                  however, ATI will gain some money through that game/demo/engine

                    So it seems AMD has the lead this time?
                    Fermi is somewhere in 2010 and with Catalyst 10.1 we have DirectX11-feature on Linux long before Nvidia can deliver something equal.

                    Congratulations AMD

                    Now kick TSMC and make them bake some chips, so you hopefully don't miss christmas (as happened with the 3870). And then bring the stock to 100$ per share

                      Really, AMD HD5000 or Nvidia GT300 series hardware is the minimum necessary to perform hardware tesselation with OpenGL?
                      AFAIW AMD introduced the hardware tesselation OpenGL extension with the HD3800.

                      Is the Phoronix article right? Someone knows for sure?

                        There is tesselation hardware in the older cards, but it isn't the same as what the newer cards have (and is less powerful). The demo requires the new tesselation hardware, because it's based on the DX11 requirements which the old unit can't support.

                        Think of it like going from SM2 to SM3. The older cards had shaders, but a new demo might still require the newer version.

                          Why is this engine such a big deal for linux? Will all the games developed with this be compatible with linux? or does it still need the extra effort?

                            I wonder whether the OpenGL extension that gives access to tesselation on the HD5xxx series is the same one as the currently experimental extension that is used for tesselation on the HD3xxx and HD4xxx series cards. I know the hardware is different, but that doesn't necessarily means that the same OpenGL extension can't be used.

                            The OpenGL requirements for tesselation could end up differently than the DirectX requirements for tesselation.

                            Anyway: good to hear we'll have it with Catalyst 10.1. I'm looking to buy myself a new and shiny HD5870 around that time .

                              Demonstration of capability is the reason it is important. Unigine has for their entire existence ensured that the Unigine is a cross platform engine.

                              This actually opens up their market beyond games into visualization and media production - have a look at their partner page on unigine.com, gaming isn't the only market that needs good visuals.
