Advanced search tips: use spaces to require multiple terms (AND), | for alternatives (OR), wrap phrases in quotes (="a b"), =term for exact match, 'term to include, !term to exclude, ^term to match prefix, !^term to exclude prefix, .ext$ to match suffix, and !.ext$ to exclude suffix.

Functions

point_line_distance

#

Shader defs requirments:

šŸŸ¢ WIREFRAME_WIDE

unsigned perpendicular distance from point p to the infinite line through a and b.

fn point_line_distance (
p: vec2<f32>
, 
a: vec2<f32>
, 
b: vec2<f32>
) -> f32

read_local_position

#

Shader defs requirments:

šŸŸ¢ WIREFRAME_WIDE

finds the local-space vertex position for a given vertex index by reading from the vertex buffer using the provided parameters. the vertex buffer is interpreted as an array of u32s, so the parameters allow us to calculate the correct offset for the position attribute of the vertex at the given index.

fn read_local_position (
first_vertex: u32
, 
vertex_index: u32
) -> vec3<f32>

vertex

#
@vertex

vertex_index: u32
, 
@builtin(instance_index)
instance_index: u32
) -> WireframeVertexOutput

fragment

#
@fragment
Calculates the final color of each pixel on the screen
