Hello All. I have the following problem. I have a 3D grid with regular positions and connections, which represents a volume containing several bodies (usually less than 10). The data value is determined by following rule: if position doesn't belong to any body than data=-1, otherway data= body's number. To draw this system I use the following net: INCLUDE to remove all positions with data ==-1, then ShowBoundaries,then AutoColor and finally Image.
Now about the problem itself: besides bodies I have 3D grid which gives pressure for the same volume. I need to change color of bodies according the pressure, but original color should remain the same. That is pressure should change only intensity of bodies color, so parts of bodies which lie in low pressure region become lighter(maybe untill they are completly white) and one which in the high pressure region become darker(untill they are black). I would be thankfull for any advices ;) ---------------------------------------------- Sincerly Yours Ilya Ginzburg
