The Game Roller Coaster Rampage With Stereoscopic 3D Support

July 4th, 2012 · No Comments · Stereo 3D Games

If you like Indie games then you might want to check out the game Roller Coaster Rampage, a fast paced competitive roller-coaster simulator with destructive environments and with stereoscopic 3D support. The interesting thing about this game is that it allows you to build your own tracks in real time as you ride them, and this can be a bit tricky if you try to defy the rules of gravity or to run the tracks through some solid objects, but it is also what adds some extra fun when building some extreme rides. The game does come with very decent graphics, but don’t expect too much in the form of very fine details or way too advanced effects, that however does not make it less fun and thanks to the really good native stereoscopic 3D support it is actually something worth playing for a while.

I’ve mentioned native stereoscopic 3D support and the game does support output using 3D Vision as well as Side by Side output, and though you might read that it supports Above/Below mode somewhere it is apparently not present in the latest update. There is no yet an official 3D Vision profile for the game available, but it also doesn’t need one as it works really well even without one, and since the game uses native stereoscopic 3D rendering you have to rely on the in-game menu to tweak the depth and convergence levels as the default 3D Vision keys for that will not work. There are no apparent issues in the stereoscopic 3D rendering and both 3D Vision and Side by Side outputs work very well, though you might want to play a bit with the settings to get the best results. And if you think that you’ll have to go to the main menu of the game to tweak the 3D settings as you don’t have the sliders for Convergence and Eye Separation in the options while playing the game, you should know that you have keys that can be used for these adjustments (9 and 0 for Eye separation and – and = for Convergence).

I’ve noticed some issues with the initialization of the full screen mode on the main screen of the game, though that did not prevent it from working properly in stereoscopic 3D mode and another a bit annoying thing was a strange D3D error showing when exiting the game or switching with ALT – TAB, hopefully these will soon be fixed with an update. Also some options for AA filtering would be nice, although you can force some Anti-Aliasing through the graphics drivers’ control panel to make the game graphics smoother removing all those annoying jaggies as there are quite a lot of objects in the game that could benefit from AA. And where is the option to show the speed in km/h instead of mph?

Roller Coaster Rampage is available on Steam for $9.99 USD or 6.99 Euro, unfortunately there is no demo available that you can try before you decide to buy the game. But if you like Indie games that offer simple and fun gameplay experience and with nice stereoscopic 3D effect on top, then you probably will not be disappointed by Roller Coaster Rampage.

3DTV Desktop Tool for Use With a 3D HDTV in Side by Side 3D Mode

August 25th, 2011 · 1 Comment · Other S3D Tech

3DTV Desktop is a new tool developed by the Taiwanese company Radiant Star, the one that made the 3Dfier 2D-to-3D DirectShow filter that I’ve already written about here in the blog. Their new tool has nothing to do with autoconversion to 3D however, instead it is targeted to help 3D HDTV users that manually switch to Side by Side 3D mode in order to watch some 3D content from their PC that does not support automatic activation of the 3D mode on the TV set. For example if you open a Side by Side 3D video using a normal video player and want to be able to watch it in 3D on the 3D HDTV that is connected to your computer you need to manually activate the Side by Side 3D mode on the TV, but after the video finishes and you are back on your desktop you will again have to switch to normal mode and then again the next time you wan to watch another 3D video or a 3D photo, or even a game that supports Side by Side output. In order to save you from the need of that constant switching of the TV from the remote control the 3DTV Desktop tool can instead reconfigure your desktop and 2D work environment in a way that it won’t be unusable when you have the TV set in Side by Side mode and it does not display such content. To do that when activated the tool will turn your normal work window into a Side by Side one (squashed) where the actual desktop will be shown in the left side and the right side of the display will be all in white color. This way you will be actually sending Side by Side content to the TV, so your desktop (although it will be shown in 2D) will be visible through the 3D glasses (this will not work well on autostereoscopic 3D displays) and thus saving you from constant switching of the display mode of the 3D HDTV.

Now this may sound as really useful tool for some people and it actually can help quite a lot, but there is some more work needed to be done on it in order to have it even better and more functional, especially considering the fact that it is a commercial product and not a free one. There are also some important requirements that you have to meet in order to have the 3DTV Desktop tool working properly on your computer and doing exactly what it was meant to. There is already an evaluation version available that you can download and test on your computer, it is time limited to 10 minutes of use and to remove the time limit you will have to spend $25 USD for a license, a bit high if you ask me $10 USD for it (the $25 USD price was set there initially by mistake). Be sure that you have the Windows 7 with the Aero interface active as it is required for 3DTV Desktop to work properly, not sure if it will work with Aero on Vista, but it may as well. Another important thing that you should be well aware of is that when at 3DTV Display tool is active there would be 2 cursors on the screen. The thinner one is the one you should look at, and as this is the limitation of the product there are no plans for fixing it. A good thing is that the 3DTV Desktop tool does not need installation, you can just run the executable and it will appear in your system tray, from there you can enable and disable it and you can switch to the Side by Side output “CTRL + 3” and hitting “CTRL + 2” will bring you back in normal output of the display, so there is no need to actually stop the program. When active the 3DTV Desktop tool will monitor the top Window in focus and when it becomes in fullscreen it will automatically switch to normal mode so that you can watch the full screen video in 3D automatically. This is especially useful when you play Side by Side 3D videos from a video player or from a website such as YouTube for example.


I did play a bit with the tool and have to mention a few things that I’ve noticed that you should know about. First of all having the right part of the picture sent to the 3D HDTV all in white will make the image from the left part of the Side by Side output seem brighter, but it may also make what is displayed there look distorted. A better solution for that would be to just have the left and right parts (frames) of the Side by Side output show exactly the same image, so you will still see a slightly darker 2D version of your desktop for example. That however can be done at the cost of some extra performance loss, but some things better be done with some performance loss and retaining the best possible quality than not. And talking about quality another thing comes to mind, the halving of the actual resolution of the display and then stretching it again when displayed on the 3D HDTV means some loss in image quality and detail due to the use of image resizing (Side by Side squashed image). And here apparently not very high quality resize algorithm is being used, again probably due to concerns of requiring more resources, however here it is totally justified to sacrifice some performance for better quality. The resize algorithm being used does produce bad quality and loss of more detail in my opinion and after replicating the effect using Bicubic resizing produces better results and retains higher image quality. The algorithm currently being used for resizing currently leads to loss of detail, so that some text with small font size can easily become unreadable while it may still remain readable with Bicubic resize. The two photos above show the original output of the 3DTV Dekstop tool in Side by Side format as well as a simulation of how it will look on a 3D HDTV by resizing the already squashed left frame to full resolution.


The two photos above show a simulation of the same thing that the 3DTV Desktop tool does but using Bicubic resize method. On the left you see the Side by Side squashed output, retaining higher quality than what the tool’s resize method does as well as the simulation of how it will look like on a 3D HDTV after being stretched again to full screen. There is huge difference in the readability and usability of text with small font size such as the browser’s menu, the URLs of websites, even the names under the icons of programs on the Desktop for example. The authors of the tool recommend to just scale the font size, a solution that may help, but can also be not so comfortable to the way you are used to working on your computer. So using a better resize algorithm and producing better quality is a must here in order not to hurt the usability for the sake of not sacrificing some performance. And finally the dual cursors, that can be quite annoying, but it seems that the issue cannot be avoided according to the authors of the software. But if you happen to know a way how to do it, then you might as well give them a tip to fix it. Still you are welcome to try the 3DTV Desktop tool, you might find it useful in your way of using your computer with a 3D HDTV as a display instead of a 3D monitor.

Sailboats a Stereoscopic 3D User Recorded HD Video For Download

May 29th, 2010 · 6 Comments · 3D Movies & Videos

The user 3D Frank from the Nvidia 3D Vision Forum has shared another interesting stereo 3D video that he made, this time instead of a Bear Encounter he recorded some boats sailing into the sea. The video is in a Side by Side format in 1080p half horizontal resolution (squashed), so you need to select 16:9 aspect ratio in the 3D Vision Video Player and enable deinterlacing. It has been recorded with a custom 3D rig using two Canon Vixia HF S21 digital cameras, controlled with a LANC Shepherd Pro in order to have them perfectly synchronized. Don’t forget to leave your comments if you download and watch this short video and also if you shot or created some stereo 3D videos or 3D photos yourself and want to share them with other people, don’t hesitate do drop me a line, write in the comments below or in the forum, so they can be featured on the website and reach more people.
