Enum ParallaxMappingMethod 

pub enum ParallaxMappingMethod {
    Occlusion,
    Relief {
        max_steps: u32,
    },
}

The parallax mapping method to use to compute depth based on the material’s depth_map.

Parallax Mapping uses a depth map texture to give the illusion of depth variation on a mesh surface that is geometrically flat.

See the parallax_mapping.wgsl shader code for implementation details and explanation of the methods used.

Variants

Occlusion

A simple linear interpolation, using a single texture sample.

This method is named “Parallax Occlusion Mapping”.

Unlike ParallaxMappingMethod::Relief, only requires a single lookup, but may skip small details and result in writhing material artifacts.

Relief

Discovers the best depth value based on binary search.

Each iteration incurs a texture sample. The result has fewer visual artifacts than ParallaxMappingMethod::Occlusion.

This method is named “Relief Mapping”.

Fields

max_steps: u32

How many additional steps to use at most to find the depth value.

Implementations

impl ParallaxMappingMethod
