Best way to achieve color by data?
Hi, do you guys have any opinion about fast way to generate geometry with color values from data?
I found above picture, which looks most similar with what I want to achieve,
while my 3D model is not a sphere(rather cone-like shape), and it should be semitransparent.
I'm considering two options, projector/decals or shader programming.
The problem of shader programming is that the geometry might be too complex,
so that It might be hard to formulate the surface color of intended position...
The problem of projector/decals is that I'm not sure if I can get fancy looking result from those methods, and I cannot take a risk to purchase assets..
Is there anyone who can advise me?
Could you bake a texture from your data, with the mapping of the alpha and colour, then just apply it to a translucent material on an object? Does it need to be animated?
Yes it should be animated...but not much. See the picture in my reply below. The dividing region should be changed dynamically.
What do you mean by "the problem of shader program$$anonymous$$g is that the geometry might be too complex"? All geometry is sent to a shader program in order to be drawn on the screen, so I can't think of how a geometry could be too complex.
You will have to write a custom shader, and you will pull your hair out.
Let's say that there is a cone model and I want to color it with 3 different colors through length direction.(like below) Is it will be easy to make intended effect as I described? If yes and from the comment of Raresh, I think I should program the Shader. I just wanted to listen your opinion.
