Hi,all:
I have a question about color. I have many points,Point3f,whose
coordinate is (x,y,z), z represent Temperature,for example,x,y represent
position. I want the minimum z value represent the Blue color, the maxium z
value represent the RED color, the z value between the minimum and maximum
should get the proper color according to their value according to
interpolation of z, so that when you look at the color, you can know if it
is cold or hot.
How can I get the color's RGB value for all of the Point3f points? What is
the algorithm to do it?Can anyone give some idea or code example about it or
point me to some websites?
Thank you very much!
David
