- Our user group had a demo the other night of OpalVision, the new 24 bit
- graphics card (see review in c.s.a.reviews group).
-
- Well, it really is impressive. It was running on a '2000 with a 25MHz
- GVP '030 card, 1Mb Chip RAM, 9Mb Fast RAM. On this setup, it really was
- fast. Most things were as fast as DPaint in hires, 4 bit. Brush stamps
- were instantaneous, but painting freehand with a decent size brush left
- gaps between stamps (ie. it couldn't keep up with the mouse). This is
- really a minor thing, but gives you an idea of the speed.
-
- The screen used was a massive Sony monitor/TV with RGB input, and the
- display was incredibly sharp. Colours were extremely vibrant, with no
- visible bleeding at all. One of our members remarked "Does real life
- look that good ?" ! It looked way better than any TV, an because it is
- in 24bit, there is very little flicker.
-
- The interface would have to be the slickest I've seen on any paint
- program on any platform. eg. in the artist tools requester is a list of
- available tools, each with an associated "icon". These icons were in 24
- bit, and a work of art in themselves. For the pencil tool, there was a
- picture of some colour pencils, for the airbrush a very arty looking
- spray can. The file requester has miniature versions of the pictures in
- each directory !
-
- I really liked the rub-through function. You have two pages, and where
- you draw, the back page shows through. However, you can set an 'origin'
- on the back page so that no matter where
- you paint on the front page,
- that part of the back page will show through. The guy giving the demo
- (David Jacobs) set an origin on a girl's face on the back page. When he
- painted on the front screen with the airbrush, the face gradually showed
- throw the more he painted, and the edges were fuzzy. No matter where he
- painted, the same face would show through.
-
- For most of the demo we were really impressed by the picture quality,
- then he said he was in LORES ! (1Mb chip RAM is a bit limiting).
-
- The paint program is based very much on DPaint, so you already know how
- to use it. Even the key equivalents are identical where possible. Most
- of DPaint's functions are included except perspective, brush fills
- (though shapes filled by the brush are supported), morphing and
- animation. Filling and stencils are controlled by a tolerance on hue,
- saturation, value or all three. There are dozens of image processing
- functions available eg. emboss, solarize, noise and others I can't
- remember.
-
- One really nice thing is that tools (pencil, chalk, water colour etc),
- image processing functions, textures etc are open ended so that more can
- be developed and added in by the user.
-
- Oh yeah, the textures. Textures are defined in some kind of fashion
- combining bitmaps and algorithms. I guess this means we'll see all kinds
- of fractal simulations of marble, wood, rock, cloth etc.
-
- I have only seen DCTV and ToasterPaint in the 24 bit arena for the
- Amiga, and OpalPaint wipes the floor with both of them. It is the first
- serious competitor to Adobe Photoshop on the Mac that I have seen on the
- Amiga.
-
- One drawback though (well, not necessarilly). It outputs RGB only, so
- you need some kind of converter to go to video. Also, the ouput is
- interlaced which aint too bad, but still not as good as a 'real' monitor
- display if your going to use it all day. Opal do have a de-interlacer in
- the works though.
-
- Other things mentioned on the night :
-
- * the Scala guys gleefully took one home when they were here for the
- Sydney WOC Expo. Scala would be mind blowing on this thing !
-
- * an external version will be released, and a display only version for
- low end systems. These may be one and the same product.
-
- * in the future, full screen, full rate 24 bit animation.
-
- * a 'Pro' version of OpalPaint available later at extra cost.
-
- I hope this becomes the defacto 'standard' Amiga video device,
- especially in PAL countries where the Toaster is not yet available. In
- some ways it is better than the Toaster and is modular.
