Colors
 
Hi,

I was working with Vizard and I tried to change the color of some objects throught the script but I am not sure how to name some colors. Is there any link where I could find the way Vizard labels hues?

Thanks,

Vinicius

Hi,

Vizard uses RGB to specify color values. Each component is specified with a value between 0 and 1. Here is a link to the Wikipedia page on RGB:

Thanks, I've figured that out already. My problem is that sometimes colors have names like SKYBLUE and I don't know how exactly the other RGB colors are called.

Hi,

Vizard defines some common color values. Here are the names and values:
Code:

WHITE        = (1,1,1)
BLACK        = (0,0,0)
GRAY        = (0.5,0.5,0.5)
RED                = (1,0,0)
GREEN        = (0,1,0)
BLUE        = (0,0,1)
YELLOW        = (1,1,0)
ORANGE        = (1,0.5,0)
PURPLE        = (0.5,0,0.5)
SKYBLUE        = (0.5,0.5,1)

If you need another color then you will need to define it yourself.

Hi, I have a further question. How do I map a color in Vizard, like (0.5,0.5,0.5) gray, to a color represented by 8-bit? Is it (128,128,128) in the example?

Yes, the following code will apply that color to a box:

Code:

import viz
import vizact
viz.go()

import vizshape
box = vizshape.addBox(pos=[0,1.8,4])

vizact.onkeydown(' ',box.color,[0.5,0.5,0.5])

You can press Alt + 1 in the Vizard editor to display a color dialog that inserts RGB values in the script for you.

That's very helpful. Thanks!
