Generate a 3D-rendered visual showcasing the three different types of glial cells: astrocytes, oligodendrocytes, and microglia. Use a reddish and orangish color palette for the cells, with each type slightly differentiated by tone but maintaining the overall warmth of the palette. The astrocytes should have a branching structure with a soft glow, the oligodendrocytes should feature compact, smooth forms with connections to neurons, and the microglia should appear more dynamic and spiky, indicating their immune function. Place the cells in a clean, floating environment, with the background using a subtle gradient of warm light, transitioning from soft orange to pale peach. The style should be realistic, professional, and visually striking, emphasizing the unique shapes and functions of each cell type."
