3D medical educational animation, a full-body frontal medium shot of a male (natural human proportions), a semi-transparent anatomical model (muscles in deep brown-red, bones in white, with a semi-transparent quality); the shoulder/chest/elbow/knee areas are highlighted in an orange-yellow glow (with a dynamic, soft flickering + gradual diffusion effect), the camera slowly rotates around the body (360° slow rotation) to showcase the entire figure, against a dark gradient background; the 3D medical visualization rendering has clear semi-transparent layers and realistic textures, the animation has a soothing pace, emphasizing the dynamic highlight effects in the key areas.
