Implementations

impl RenderUniformCollection

pub fn set_uniform_f( &mut self, shader_program: u64, name: &str, val_type: UniformType, vals: &[f32], )

set uniform values to be sent to shader later

pub fn set_group( &mut self, shader_program: u64, group_id: u64, names: Vec<String>, ) -> Result<(), &'static str>

group uniforms together

pub fn get_group( &self, group_id: u64, ) -> Result<Vec<(String, UniformType, Vec<f32>)>, &'static str>

pub fn send_uniform_group(&self, group_id: u64) -> Result<(), &'static str>

send the uniform values belonging to the uniform group to the shader

Trait Implementations

impl Default for RenderUniformCollection

fn default() -> RenderUniformCollection

Returns the “default value” for a type.
