Texturing

Mipmaps are automatically generated when requested by the texture constructor or by one of the vl::Texture::prepareTexture*() methods. The texture generation uses the hardware acceleration where available otherwise glu is used.

You can use them as usual:

vl::Texture* texture = ... init texture ...
glBindTexture(GL_TEXTURE_2D, texture->handle());
glTexSubImage2D(GL_TEXTURE_2D, ...);
glBindTexture(GL_TEXTURE_2D, 0);
