3D: Adding lights and shadows

Lighting and shadows play a crucial role in creating realistic 3D scenes. They help to enhance depth perception and add realism to objects. Here are some techniques for adding lights and shadows to your 3D creations:

Point Lights:

Point lights are a type of light source that emits light in all directions from a single point in space. They are commonly used to simulate light bulbs or spotlights in a 3D scene. You can adjust the intensity, color, and position of point lights to create different lighting effects. Point lights can cast shadows on objects, adding depth and realism to your scene.

Directional Lights:

Directional lights are like the sun – they emit light in a particular direction and have no finite source. They are often used to create natural lighting effects in outdoor scenes. Directional lights can cast shadows that mimic the look of sunlight shining down on objects. You can adjust the intensity and color of directional lights to create different moods in your 3D scene.

Shadows:

Shadows are essential for creating depth and realism in a 3D scene. Objects cast shadows on other objects based on the position and intensity of light sources. You can adjust the shadow-casting properties of lights to control how shadows appear in your scene. Soft shadows can create a more realistic and natural look, while hard shadows can add drama and contrast to your 3D creations.

Overall, adding lights and shadows to your 3D scenes can elevate the level of realism and depth perception. Experiment with different lighting techniques and shadow settings to create stunning visuals that captivate your audience.
