With over a decade of experience in C++ programming, I am confident in my ability to tackle your project head-on. My team at Edward Juniors has consistently delivered high-quality and professional results, and we are committed to ensuring our clients' satisfaction. In regards to your project, the integration of the classic WASD camera controls is clearly achievable with our skillset. We understand the need for a clean solution that doesn't compromise on existing dependencies, and we promise to update the necessary source files with clear and concise comments on the sections we touch. Therefore, you can rest assured that the changes made will be easily understandable and maintainable in the long run. Furthermore, our proficient knowledge in OpenGL adds immense value to this ray-tracer project. We have an in-depth understanding of how a proper view matrix or equivalent camera logic works. This means we will not only solve your existing issue but also add seamless, frame-rate-independent motion to enhance overall user experience. Trust Edward Juniors with your project - we'll ensure a smooth transition from mouse-only movement to incorporating WASD keys that aligns perfectly with your objectives.

Hi, Can start now, $30, done in an hour or two. Good news is the hard part is already there: your mouse look works, which means the camera has an orientation (a forward/right basis) and a view matrix being built each frame. So WASD isn't new camera logic, it's just translating the camera position along those existing basis vectors (forward/back on W/S, strafe left/right on A/D) and feeding the updated position back into the same view matrix the mouse already drives. I'd wire the key state into that instead of one-shot key events, so holding a key gives continuous motion rather than a single step. The bit you specifically flagged, frame-rate-independent motion, is the detail that matters: movement has to be multiplied by delta-time each frame, otherwise the camera moves faster on a fast machine and slower on a slow one. I'll compute a per-frame delta and scale movement by it so speed is consistent regardless of frame rate, which is what makes it feel smooth. I'll work directly in your existing C++/OpenGL code, leave the external dependencies untouched as you asked, and return the updated source with clear comments on exactly what I changed. 15 years of C++ including plenty of OpenGL and camera/view-matrix work. Anything on movement feel you want, fixed speed, or a run/sprint modifier? Karol

Adding WASD movement to your raytracer at netpipe/OpenGL-Demos means building a proper view matrix driven by keyboard state and wiring it into the existing render loop without disturbing the mouse look that already works. The plan: track key-down state for W/A/S/D, compute frame-time-independent movement along the camera's forward/right vectors, and update the view matrix each frame before the scene draw. Since mouse rotation is already functional, camera orientation stays untouched — only translation gets added, keeping the change minimal and easy to review. Comments will mark exactly which sections were modified so you can verify quickly. Ready to dive into the repository and get WASD moving today.
