Great for Ray Tracing Too!
589791
I bought this book then jumped to the last chapter.  With its help, I wrote a fairly decent ray tracer in under two weeks (which is no small feat considering I'm a full time mom of a two year old!).  Of course, OpenGL is not used much for a ray tracer.  As a result, I did not use the book for OpenGL purposes but rather for its logic and instruction.  The code design is object oriented and very clear and easy to understand. The book uses GLUT which is platform independent.  However, I transformed the concept to Windows with no problem (I do have prior knowledge of the system though).

Only reason for 4 stars is I reserved 5 stars for more highly visible display on the Xminilab series.

An Xprotolab was used as display on an audio project for church and is a big hit. We are now working in the larger, just as functional Xminilab which we will review later.

For rapid prototyping of a display for real time and FFT spectrum this is a wonderful, affordable, ready to run component ! The Xscopes software looks good and is improving to allow this to be hooked up ad a PC in circuit scope.

This is great for anyone who uses a CAD or 3D application, but even more so it you use several. I was jumping back and forth between Rhino, Fusion 360, SolidThinking Evolve, Keyshot and a couple others. It became impossible to remember the navigational controls of each program. This great device eliminates all of the navigational confusion, because with it, they all navigate/function the same way. I've been using it for a few months now, carrying it to and from work everyday in my backpack. It's held up great. Very good quality device, I'd never want to go back to just a mouse.

I love this video card. It makes all the difference in gaming to be able to see the shadows, see long distances, add ridiculous amounts of detail without sacrificing playability. This card is reasonably priced and uses low power.

Only technical problem was it taking over my audio for its HDMI (I don't use the HDMI output) and I had to switch to different audio output ports. This was a minor thing. I had to plug my speakers into the front of my computer instead of the back. Still I don't have any other video cards that steal the back mounted ports. I gladly trade the port for the performance with such low power requirements. I have a 350w power supply that came stock with my HP and it's plenty to drive everything. This saves in that it costs little to begin with and it doesn't require you to upgrade your power supply to accommodate it.

Bring on the games!

I installed this on an older PC running Ubuntu 10.10 so that I could make use of an extra monitor.  After a couple of reboots and installing the latest drivers, this guy was pushing 2 monitors with no problems.  The picture is crisp and clean and the card handles the all of compiz's 3D effects with aplomb.
I don't know that I would recommend this for gaming, but it is just the thing for anyone trying to convince an older PC with PCI-E to run dual monitors.

I'm a 3D artist and recently got a big job on converting an existing stadium into a usable venue. One can imagine the size and scope of this project, it is huge, I'm running 350 mb file to a 500 mb file on 3D studio. So it tanked my old rig and I decided on this. I was happy to see it has a couple of CUDA cores on it so I can try my hands on Vray RT, and it was working great. shifting view and re-render takes 5-7 seconds on a viewport. Very cool.

As far as gaming, I am an old timer, I played PONG on it's first launched on street corners. I paid $500 for a graphics card on my 80386/16 mega hz so I can play wing commander. So to me these graphics are great. I can throw in a bunch of option on any game and it will take it in stride. (not all the way up ) but 60-70%. I'm happy with that. If anyone is complaining about it's graphics capability. you can always open it up and change up to a Gtx class card, it only cost you $400-$500. but Bang for your buck. this is IT!

It's also very quiet and well put together, I'm happy with the speed and performance. Styling is cool, it's improved some so that older guys can use it too. It used to have a face shield which takes some getting use to.

I got this a few months ago and have been always learning new things about it. I use it to record my Nintendo 64, Nintendo Gamecube, Xbox 360, and Xbone. After tweaking the settings i got it working great. I use it for my youtube channel and my twitch streaming. you can stream right from the Elgato software or use like OBS as well. Sometimes it will get buggy but it was usually a user error. 10/10 would reccommend

I've wanted a 3D-capable 1080p projector for a long time, and with the 3020 Epson has succeeded in making a high-quality projector that is quite affordable. The picture quality is stunning. I wasn't sure whether it would be bright enough for use in the daytime with my blinds drawn, since some sunlight still gets in. I needn't have worried; at 120-inch diagonal it has brightness to spare even in econo-mode.  The supplied RF 3D glasses work quite well, and I've never had them lose sync, unlike the earlier generations of infrared glasses.  I've also successfully used this projector with Samung RF glasses, which aren't quite as nice as the Epson glasses, but only cost 1/4 the price.

I've been delighted with the performance of the 3020 with Blu-Ray and DVD discs (played using PowerDVD on a PC) and Roku streaming.  I'm not a huge gamer, but I like Portal and Portal 2, and they are fantastic in 1080p stereoscopic 3D at 120 inch diagonal! (A third-party program is necessary to render these and most games in stereoscopic 3D.)

I'm a programmer, and for the last decade have needed reading glasses with my desktop and laptop displays. Using the 3020, I can sit in my recliner and use my wireless keyboard and mouse, and see the whole 1920x1080 computer display in perfect focus without glasses.

Compared to Epson's higher-end models, the 5020 and 6020, the 3020 doesn't do quite as well on black level, and it doesn't have lens shift, or the motorized lens cover of the 6020. However, it's $1000 less expensive than the 5020. For most home theater situations lens shift isn't needed, and $1000 is a lot to pay for a modest improvement in black level.

Overall I'd have to say that this is one of the best values in AV equipment I've ever seen.

I love this thing! I have painted the red x bezels black and also added amber tint film since I bought it, and I love the way it turned out! When I was modifying it I was looking at the internals and these things are built well! Definitely would buy again, and likely will be buying another soon! I also love the projector lenses (5D) they throw the light SO FAR!

Its a great tool for 3D gaming and watching 3D movies.  Make sure you have PowerDVD 10 and a 3D TV or monitor as well.

Great! I use this for processing my photos. It recognizes Adobe RGB and has a matte finish (absolutely worth the money!!) And it's huge! Would recommend this to anyone who works with graphics/imagery for true colors (with a calibration) in any light.

This was bought for me as a Christmas gift. My television setup was very far from my TV and I doubted the performance of USB extensions. Especially with a component like this that would be constantly running data. 4 months later, I set it up in my new apartment. Took the risk and got a 50ft usb extension with built-in signal repeater. WORKS. PERFECT. The mood light is really cool for generic browsing and a nice effect when you leave it up playing music at a party. Screen grabbing is about as good as it can get. There's a bit of a learning curve with the software and the LED RGB balance settings were hard to find. My kit was a little heavy on the green. Toned that down and it looks way better. Could probably use some further tweaking, though.

The screen-grabbing mode works great with:
Desktop graphics and general PC work.
Playing full-screen videos (adjust your profile to sample the screen correctly based on aspect ratio)
"Project 64" Nintendo 64 Emulator for Windows
ZSNES Super Nintendo Emulator for Windows

The screen-grabbing does NOT work with Steam PC Gaming! Something about Steam makes the Prismatik program completely miss the PC's graphics output. It'll catch it if you're playing your game in windowed mode. So far, There are applications that can make a windowed application go full screen, but with games, there's a really noticeable degradation in performance. I just put the mood light on when playing Steam games.

I have not tried to run this on a Mac.

Just used on of these in a build for my wife's grandmother, and it worked great.  A wonderful option for systems that don't need dedicated graphics for gaming, computer art, etc.  Speedy and efficient.

I had WayPoint 205 for 3 months now and love it.  It has great screen graphics and shows the detailed street maps, not just the simplified maps used by some other navigation systems that I looked at before I purchased.  It has very fast zoom in and zoom out that makes it easy to look at the detailed map.  Mobile Crossing released the newest US maps recently and since I owned the unit less than 3 months, I could download and upgrade for free.  The built-in Map Loader made this upgrade extremely easy - no CD or PC software to mess around.

I also use it for my personal address book, appointment book, MP3 player, photo album, etc.  I carry it with me everywhere.

This thing is awesome.  I've used it for both my optical mouses and my laser mouse. The tracking on it is dead on, and I've actually used it for some CAD work. Very well made, with nice smooth edges and a slight bevel.  The rubber feet are about 1.25" diameter "donut" shaped pieces that grip VERY WELL on any surface that I used it on.  I got the silver one, and I see it's also offered in black, but since I use this with my Apple Mac products, it matches perfectly.

I have gotten this as a gift from family. This is a great hand tracker for games and VR (as far as I know I don't have a headset yet) But it is great if you know what makes it not work it and what makes it work best. What makes it work best is the latest orion update and also not having anything on you hands that are reflective as this can effect the tracking. I have never been able to complete the calibration but I feel like the Tracker works fine without it. I cant wait for to get a VR headset to try this device with because I herd it was so much more interactive when you use it with a VR headset.

We picked these up (two initially, just bought two more for four total) for playing legacy Nintendo 64 games on our theater PC.  Nothing like RoadRash64 on a 100" screen!

The controllers fit our hands well, are of suprisingly good build quality, and all buttons feel solid.

Multiple controllers (which I could find no-one talking about) actually work easily and well.  We have all four plugged into a USB hub, sitting next to one another, and they all appear in the game controller control panel in Windows XP.  My only complaint about them is if you unplug and reconnect the receivers you have to reassign controllers to receivers.  This makes it difficult to label controlers 1 through 4, as they may change.

All in all, great controller!  I'd highly recommend it!
