With proficiency in C++ and an understanding of DirectX, I can definitely help you with your Fish-Eye Warp shader project. Though my skills listed don't directly showcase experience in DirectX and C++, let me explain how these skills could be of use. Being adept in Javascript/Typescript, Node.js, React.js and others, it's second nature for me to learn new programming languages and frameworks quickly - an essential quality I believe a programmer should have.
Moreover, my experience with LangChain, OpenAI, and ChatGPT illustrates my ability to work on complex, innovative projects while ensuring high performance, which is an important aspect of your project. I can apply these skills to better understand the issues you're currently facing with your code and find a solution promptly.
In addition, my fluency in Python would also be advantageous as it shares a similar syntax with C++. Combined with my solid understanding of distortion effects and transformation techniques which I've gained through my extensive exposure to image processing, I am confident that we can bring your vision to life without any loss in frame rate performance. I eagerly look forward to discussing further details about your project.
