# rlFbo
A utility class for using multisampled framebuffers in [Raylib](https://github.com/raysan5/raylib).
Raylib's default framebuffer objects `RenderTexture2D` are not multisampled by
default. To use multisampled framebuffers in Raylib, you can use OpenGL APIs.
This class simplifies this step.
## Installation
### Manual Installation
You can directly copy `rlFbo/rlFbo.cpp` and `rlFbo/rlFbo.hpp` in to your project. Note that you will need `include/glad/glad.h` for raw OpenGL calls to work in Raylib, as the OpenGL context is initialized by `glad`. If you do not already have the header file, you can also copy it from this repo.
### CMake
Clone the repo and install the library.
```sh
cmake -S . -B build -DCMAKE_INSTALL_PREFIX=/desired/install/path
cmake --build build --target install
```
In your `CMakeLists.txt`:
```cmake
find_package(rlFbo)
target_link_libraries(YOUR_PROJECT PRIVATE rlFbo)
```
Alternatively you can clone this repo to your project root and in your `CMakeLists.txt`:
```cmake
add_subdirectory(rlFbo)
target_link_libraries(YOUR_PROJECT PRIVATE rlFbo)
```
## Example Usage
Below is an example of how you can use `rlFbo`. For more information, please
read the [header](rlFbo/rlFbo.hpp) file.
```cpp
#include
#include
void main(){
InitWindow(1280,720,"rlFbo Demo");
rlFbo myFbo(1280,720);
while(!WindowShouldClose()){
myFbo.begin();
ClearBackground(WHITE);
DrawCircle(640, 360, 300, RED);
myFbo.end();
myFbo.draw();
BeginDrawing(); // needed for event polling
EndDrawing();
}
}
```
