Public Member Functions | |
| void | init () |
| Initializes a new FrameBuffer (deleting the old one if it existed) | |
| void | use () const |
| Binds this FrameBuffer. | |
| void | set_texture (GLuint idx=0) const |
| Sets which texture to draw to. | |
| void | unuse () const |
| Binds the default FrameBuffer (i.e. the screen) | |
| GLuint | add_texture (GLuint width, GLuint height, GLint min_filt=GL_LINEAR, GLint mag_filt=GL_LINEAR, bool rgba=true) |
| Returns index of added texture. | |
| GLuint | get_tex (GLuint idx=0) const |
| Returns id of texture associated with GL_COLOR_ATTACHMENTidx. | |
| GLuint | get_width (GLuint idx=0) const |
| Returns width of texture associated with GL_COLOR_ATTACHMENTidx. | |
