Hi :)

Anybody can post a formula to resize a 3D object
from image size (width and height),to keep the
good aspect ratio ?

See ya :)

Lol :)

Imagine, i load a texture, and i want to texture a cube with
this texture. But i want to scale the 3D object from the
width and the height of the image because i want to keep
the image ratio on the textured cube.

I'm clear or not now ? :)

Example :

w# = ImageWidth(image)
h# = ImageHeight(image)
ScaleEntity cube,w/w,h/w,1.0

Comme ca?

Vous etes clair comme etang boueux :P

image = LoadImage("filaxrocks.png")
w# = ImageWidth(image)
h# = ImageHeight(image)
FreeImage image
texture = LoadTexture("filaxrocks.png")
cube = CreateCube()
EntityTexture cube,texture
ScaleEntity cube,w/w,h/w,1.0

Doesn't that work?
