Texture: .h, .cpp¶
The Texture class represents an image as used by OpenGL. It sends image data (either from a file loaded by DevIL or supplied by the user) to OpenGL and stores the OpenGL handle of the texture.
How to use it?¶
Create it either by using the contructor with a path:
Texture::Texture(fs::path); //eg. auto myTex = sge::Texture("path/to/file");
(which will load the texture from the supplied file) or the contructor with the raw pixel data:
Texture(GLubyte* data, int w, int h, GLenum format); //eg. auto myTex = sge::Texture(myDataPtr, 512, 512, GL_RGB);
Which will load
w * h * 3 bytes from myDataPtr and send it to OpenGL with the format of
format (for example
Refer to the .cpp file (more specifically,
void loadFromFile() and
void makeTexture()) to see how the textures are loaded from files or raw data.
