[Visualpython-users] materials.texture(mapping=????)

[Khaerul A. <kha...@gm...>]

Hello my great friends!
I've been trying vpython today and my project target is to display a
series of image into faces... one image for each face, but now it's
not really the problem.

My problem is at the:

materials.texture(mapping='mode')

which I dont have any clue what value to fill in the 'mode' to pass
into the mapping argument, is there any decent resources/reference for
vpython that I can use?
Because after awhile searching the original website I can't find any
"API reference" or something like that.

In case you people want to see my code, here it is:

from visual import *

#using P.I.L (Python Imaging Library)
import Image

#create frame object
f = frame()

#create a red face
model = faces(frame = f)
model.append(pos = (-3,0,-3))
model.append(pos = (-3,0,3))
model.append(pos = (3,0,3))
model.append(pos = (-3,0,-3))
model.append(pos = (3,0,-3))
model.append(pos = (3,0,3))
model.make_normals()
model.make_twosided()

#get material from file
name = 'wgauss'
width = 1840
height = 321
im = Image.open('w-gauss_of_v1.1_0.50_04.png')
materials.saveTGA(name, im)
data = materials.loadTGA(name)

#set model's material
model.material = materials.texture(data=im, mapping='sign')

Thanks in advance for any (helpful) reply

Khaerul,

mapping is either "rectangular", or "spherical".

Please see section below:

.. and also mapping = "sign" is available.

[Khaerul A. <kha...@gm...>]

Kadir, thank you for the hint! I think I didn't read the page thoroughly (shy)

Now I have another (related) problem, as you can see in my code there is:

width = 1840
height = 321
#an then resize
im = Image.open('w-gauss_of_v1.1_0.50_04.png')
im = im.resize((width,height), Image.ANTIALIAS)

there are the size of the bitmap i'm using and I created a bitmap from
a file an then re-size it, so after using a 'rectangular' as mapping
mode in my materials.texture() my image isn't showing as I expected.
So the real question is: how do you handle that kind of texture (not a
power-of-2 sized texture)? (because I've red it at the example in the
link that a texture has to have a power-of-2 size)

again, please, enlighten me

You just have to do what it says: Each dimension of the texture must be a
power of 2. The image will then be stretched and/or compressed to fill the
rectangle you put it on.
