Methods

impl RenderUniformCollection

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

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

group uniforms together

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

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

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