Is it posible to get my texture width and height after I buit it


glBindTexture(GL_TEXTURE_2D, Texture); //using variable Texture
....
gluBuild2DMipmaps(GL_TEXTURE_2D, GL_RGBA, Width, Height, GL_RGBA,
GL_UNSIGNED_BYTE, pData) //Get this width and height
....

AFAIK no, you have to maintain it yourself.

There's such a function you can use

glGetTexLevelParameteriv(GL_TEXTURE_2D, 0, GL_TEXTURE_WIDTH, &param);

Similar goes for height and other texture props - see Help on
glGetTexLevelParameter
