"Progress"
Full-Dome System for Full-Dome Projections into a Dome
|
|
Planetariums and smaller personal domes can provide an immersive environment for science education, virtual reality, and entertainment. Digital projection into domes, called "full dome projection" in the industry, can be a technically challenging and expensive exercise, particularly so for installations with modest budgets. An alternative full dome digital projection system is presented based upon a single projector and a spherical mirror to scatter the light onto the dome surface. The approach offers many advantages over the fisheye lens alternatives, results in a similar quality result, but at a fraction of the cost- |
|
We are introducing the new "Progress System" for Full Dome Projections in Portable Planetariums and Educative Dome at the lowest international price and with the highest possible quality, as we always do :) With our help the Full Dome Projection Revolution has rised with a very competitive price in the educative market, against the overpriced products in the international market. Portable Planetariums Home has given one more time an affordable answer to the world wide customers. |

| What is needed for a Success Full-Dome Projection ? | |||||||||
|
A Full Dome Projection needs: 1) Computer; 2) Codecs; 3) Spherical Mirror or "Fish Eye" Lens; 4) DLP Digital Projector; 5)"Warp" videos to be projected into a dome and 6) Dome |
|||||||||
| They are the following Five Requirements | |||||||||
| 1. Hardware | |||||||||
| Pentium IV - 2,4 Gb or AMD + 2500 or higher. Memory RAM: 1 Gb o Superior. Video Card: GForce 5.200 or Higher. DVD Room: 16 x or higher. Also is needed Codec Pack | |||||||||
 |
|||||||||
| 2. Codecs | |||||||||
| K-Lite Pack de Codecs para Computadora - Descarga | |||||||||
| 3. Reflection System: Spherical Mirror | |||||||||
| We choose a "Spherical Mirror" to project into the dome with digital projectors, because they are very affordable, and the result is almost the same. The advantage of the "fish eye" lens is that they can cover all the dome, meanwhile parabolic mirror cover 340 degrees (because the mirror projects a shadow). However, lens must be made in agree with the focal distance of the digital projector, and they are very very expensive. Meanwhile, mirrors can be used in any DLP Digital Projector. Choose Mirrors and you will save hundreds and even thousands dollars forpractically the same results. We provide to the customers a 60 cm (on diameter) Spherical Mirror with a luxury and strong travel box for Full Dome Projections. | |||||||||

| 4. Digital Proyector | |||||||||
|
Current Digital Projectors are based on DLP technology, better than old LCD Tehnology. DLP technology makes very dark "backgrounds" not "grays" like LCD's projectors. Also, DLP technology provides a very high contrast, brightness and resolution for sucessful projections into a dome. The client can choose any DLP Digital Projector provided by the best international companies like DELL, Sony, Sharp, etc. In this way the client will save hundreds and even thousands dollars purchasing it in own country :) The Client should keep in mind 3 considerations to choose a DLP Digital Projector: 1) Contrast, 2) Brightness and 3) Resolution. Of |
|||||||||
|
|||||||||
| course: highest values, better results :) Specially highest contrast relations result in better images. We recommend choose the highest possible contrast relation, brightness and resolution. For example the DLP Digital Projectors in the market can be found with contrast relationships between 2000:1 to 12.000:1 or more, brightness between 1800 - 2100 lumens or more and resolutions larger than 780 pixels x 1024 pixels. The price is always important, but the quality from a SXGA+ (1400x1050) is significanly better than XGA. | |||||||||
 |
We recommend a DELL 5100 MP. Bright 3,300 ANSI Lumens / Contrast Ratio / SXGA+ (1400 x 1050) | ||||||||
| In short: highest values, better results. Minimal possible values are: resolution: > 780 x 1024, brightness: > 1800 lumens and contrast relation: > 2000:1 | |||||||||
| 5. WARP Movies - Explanations | |||||||||
|
Warp is a computer effect provided by some complex edition programs. WARP effect is applied to videos and animations to avoid distortions of Dome Spherical shape. Warp effect modify videos and animations as if you see them with a "fish-eye" lens and it is necessary to see a full dome projection without distortions. Our Warp video-clips were downloaded from Public Internet Places, include a wide topics selection. |
|||||||||
| 6- Dome | |||||||||
| In any projection is necessary a "screen". Obviously for a "full-dome" projection is necessary a non-flat screen like a Dome. We produce high quality domes at very affordable international prices. | |||||||||
