Struct TriplanarProjector 

pub struct TriplanarProjector {
    pub scale: f32,
    pub sharpness: f32,
    pub axis_scale: Vec3,
    pub axis_offset: Vec3,
}

Triplanar projection for seamless texturing of arbitrary surfaces.

Projects texture coordinates from three orthogonal planes (XY, XZ, YZ) and blends based on the surface normal direction.

Fields

scale: f32

Scale factor for the texture coordinates.

sharpness: f32

Blending sharpness (higher = sharper transitions between planes).

axis_scale: Vec3

Per-axis scale adjustment.

axis_offset: Vec3

Per-axis offset.

Implementations

impl TriplanarProjector

pub fn new(scale: f32) -> Self

pub fn with_sharpness(self, sharpness: f32) -> Self

pub fn with_axis_scale(self, axis_scale: Vec3) -> Self

pub fn with_offset(self, offset: Vec3) -> Self

pub fn blend_weights(&self, normal: Vec3) -> Vec3

Compute the blending weights for a given normal.

pub fn project(&self, position: Vec3, normal: Vec3) -> TriplanarUVs

Compute triplanar UVs for a vertex.

Returns three UV pairs (for XY, XZ, YZ planes) and their blend weights.

pub fn project_single(&self, position: Vec3, normal: Vec3) -> Vec2

Compute a single blended UV for a vertex (simplified, loses some quality).
