# C API examples and testing playground
|
||||||
|
|
||||||
|
These examples are merely illustrations of how to use `librashader_ld.h`. The actual "rendering" parts of it should not be taken as "good" or well optimized code.
|
||||||
|
|
||||||
|
* `librashader-capi-tests` This is my playground to test the soundness of bindings.
|
||||||
|
* `dx11-example` This is a basic D3D11 example.
|
||||||
|
* `dx11-example-2` This is a more advanced D3D11 example based off [Minimal D3D11 pt3](https://gist.github.com/d7samurai/abab8a580d0298cb2f34a44eec41d39d) to show integration with a more complex renderer.

// This example shows how librashader can be integrated into a more advanced renderer.
|

|
//
|
||||||
|
// Whereas the first example freed and recreated a texture every frame, this uses a persistent texture for better performance.
