Re: [Nel] UTexture

[Cyril 'Hulud' Corvazier]

 

after creating a UTexture format vie the UDriver createTextureFile function

 

  _texture = driver().createTextureFile("file.tga");

 

i need a way to obtain the width and height of the UTexture file

there doest appear to be an accessor for this in UTexture

 

Yes, your're right, there is no accessor for the texture size. Anyway, NeL could tell you the size of the texture only after the texture has been used.

later in the code at the point i need to find the width and height

i have a material with the texture assigned to it and to perform

some required calculations

 

to avoid repeating something that already may exist and

for cleaner faster code does anyone know a way to obtain this information from

Utexture or more preferably from a material with a Utexture assigned to it

 

the material > texture > width / height is best way for me as it will require

a lower overhead of varibles being thrown about

Si you need to know a bitmap size from a file (tga or dds), use NLMISC::CBitmap::loadSize().

To get the bitmap file name, you will have to get a NL3D::UTextureFile interface from your UTexture object with a "dynamic_cast".

 

Otherwise, the way you can do this is :

 

- Expand the NeL 3d interface to give access to the CTexture::generate() method that forces a texture to be generated.

- Expand the NeL 3d interface to give a read access to the texture size. Be sure to call CTexture::generate() before.

 

Hld.
