You could try:
ScalarMap cmap = new ScalarMap(Temp, Display.RGB);
dpys[0].addMap(cmap);
LabeledColorWidget lcw = new LabeledColorWidget(cmap);
Then add(lcw) to your GUI somewhere and experiment with
color lookup tables that will give you a brighter image.
Or you could try computing a color table:
ColorControl control = (ColorControl) cmap.getControl();
float[][] table = new float[3][256];
for (int j=0; j<256; j++) {
table[0][j] = ... // j-th red
table[1][j] = ... // j-th green
table[2][j] = ... // j-th blue
}
control.setTable(table);
Note also that with Java3D colors can be a bit less bright,
because of the shading algorithm.
Good luck,
Bill
