[JAVA2D] Graphics cards and Performance

2007-02-23 Thread java2d
What level of graphics card is being targetted for Java2D acceleration improvements? E.g. if I buy a new Dell Optiplex, for many models the default graphics card is an ATI Radeon 1300 Pro 256MB. Will this miss out on some of the improvements in JRE6 or expected in JRE7? My interest is two fold:

Hi Chris, that's fantastic news indeed. I'll check the new jdk7 as soon as b10 is released. While waiting for your blogs, I have a story for you. Some time ago I was forced to use LWJGL in order to write an OpenGL/Graphics2D wrapper (not as complete as the real thing, but it works very well

Hi I have a applet (see code) below which behaves a little strange. It draws 2 circles with a basic stroke as its 'border'. The 1st circle is first filled then drawn; the 2nd circle the other way round. Notice how the border of the right circle seems to be thinner on the left side than on the

Hi Mark, The shader-based acceleration enhancements that we've been adding to Java 2D's OpenGL pipeline work on all shader-level GPUs, including the first-generation shader boards that came out about 5 years ago. Another way to put it: ATI:Radeon 9500 and above Nvidia: GeForce FX 5xxx

Thanks Chris. Is the situation similar for the DirectX pipeline on Windows (in terms of hardware required if not performance achieved)? My about to be retired machine has what was the standard Dell offering when it was purchased 4 years ago, an ATI Rage 128, which provides precisely no

The Java 2D image structure is mind-boggling, and I don't claim I understand all the dragons hidden inside, but I am sure that there is no get-half-of-a-pixel method somewhere in the API. Not even in the darkest corner. If I get you right. you need to do some image processing. You know the
