Hi Risto,
In
Raster ras = new Raster(
new Point3f(-1.0f,-1.0f,-1.0f),
Raster.RASTER_COLOR,
0,0,
512,512,
new ImageComponent2D(
ImageComponent.FORMAT_RGB,
new BufferedImage(256,256,
BufferedImage.TYPE_INT_RGB)),
null);
The BufferedImage size 256x256 is smaller than the raster
size 512x512 that Java3D is going to read from native so
it crash the underyling library.
To fix this always create an imageComponent will size bigger
than the raster read size.
Actually Java3D can better handle this by throwing Exception,
bug 4784249 -
readRaster crash if imageComponent size pass in is smaller than Raster size
is filed for this.
Good try to crash Java3D !
