Diffuse Mapping

StarStarStarStar

Diffuse mapping involves applying a texture to a surface to simulate a material's basic color and surface detail under diffuse lighting. This is the simplest form of texturing and used to provide an object with color and subtle texture details.

Bump Mapping

StarStarStarStar

Bump mapping is a technique that simulates small-scale bumpiness on surfaces without changing the actual shape of the surface. It uses a grayscale height map to give the illusion of surface relief.

Refraction Mapping

StarStarStarStar

Refraction mapping is a texture mapping technique that simulates the bending of light as it passes through a transparent or translucent material. It's often combined with transparency effects for realism.

Displacement Mapping

StarStarStarStar

Displacement mapping is a technique that modifies the actual geometry of the surface according to a texture map. This creates true surface relief as opposed to the illusion of relief, allowing for highly detailed surfaces.

Emissive Mapping

StarStarStarStar

Emissive mapping is used to make parts of a surface appear as if they are emitting light. This texture mapping defines the color and intensity of the glow emitted by different areas of the surface.

Normal Mapping

StarStarStarStar

Normal mapping is a technique that creates the illusion of complex surface details by using a normal map, which is an image that stores a color-coded version of the surface normals. It provides more detailed lighting effects compared to bump mapping.

Parallax Mapping

StarStarStarStar

Parallax mapping is an enhancement of bump mapping, providing a more pronounced sense of depth as the viewer's angle changes. It uses height information to displace texture coordinates, simulating surface irregularities.

Specular Mapping

StarStarStarStar

Specular mapping uses a texture to define the specular highlights of a surface by varying the intensity and color. It allows different parts of a surface to have different shininess and color highlights.

Opacity Mapping

StarStarStarStar

Opacity mapping utilizes a texture to define the transparency of a material on a surface level. Areas can range from fully opaque to fully transparent, allowing for complex object silhouettes.

Reflection Mapping

StarStarStarStar

Reflection mapping, or environment mapping, enables surfaces to reflect their surroundings without the need for complex ray tracing. It uses a pre-rendered image of the environment, such as a skybox, to simulate reflections.
