AI Technical Summary
Existing cartoon-style multi-light source rendering solutions cannot achieve a unified and flat cartoon rendering effect while maintaining the uniqueness of the light and dark boundary line, and cannot present rich color changes and highlight performance under multi-light source lighting.
By determining the synthetic lighting direction corresponding to each vertex of the 3D model, and combining the preset light color, backlight color, and normal direction, the lighting parameters of point light sources and parallel lights are fused to render the 3D model, ensuring the uniqueness of the light and shadow boundary and the uniformity of the colors.
Under multi-source lighting, the uniqueness of the light and shadow boundary on the surface of the 3D model and the consistency of the cartoon rendering style were maintained, while rich color variations and specular highlights were achieved.
