Implementations

impl PointCloudRenderData

pub fn new( device: &Device, bind_group_layout: &BindGroupLayout, camera_buffer: &Buffer, positions: &[Vec3], colors: Option<&[Vec4]>, ) -> Self

Creates new render data from point positions.

pub fn update_colors(&self, queue: &Queue, colors: &[Vec4])

Updates the color buffer.

pub fn update_uniforms(&self, queue: &Queue, uniforms: &PointUniforms)

Updates uniforms.
