Red dahlia flower rendered with luminous petal structure against dark background.

Three-dimensional digital rendering of a dahlia specimen displaying geometric petal arrangement in graduated red-orange spectrum. Central disc florets exhibit densely clustered spherical forms in crimson coloration. Individual petals demonstrate volumetric modeling with specular highlights and subsurface light transmission creating luminance gradation from orange edges to deep red interior zones. Lighting positioned to emphasize dimensional relief and chromatic transitions. Background rendered as uniform dark tone providing maximum contrast saturation.
