To eliminate the harsh pixelation caused by rendering low-resolution grid cells directly to the main display, the rendering pipeline was updated to use an offscreen canvas matching the exact simulation grid dimensions. Fluid density values are now written directly into an ImageData pixel buffer on this offscreen canvas. When drawing to the screen, the offscreen canvas is scaled up with high-quality bilinear interpolation enabled (imageSmoothingEnabled = true), seamlessly blending the pixel boundaries. This achieves a smooth, continuous fluid flow with soft gradients without impacting the performance of the underlying physics simulation.
