[Texture.hpp]
|
|
|
|
The Texture class abstracts the file opening, data loading and binding steps of Open GL
|
|
texture creation. Currently it only supports loading GL_TEXTURE_2D with GL_RGB8 pixels
|
|
and automatic GL_NEAREST mipmapping. Support may be added for users to pass in their own
|
|
pixel data, to customize mipmapping, and more.
