Struct ShaderExecutor 

pub struct ShaderExecutor { /* private fields */ }

Executes shader programs on pixel data using software rasterisation.

Implementations

impl ShaderExecutor

pub fn new() -> Self

Create a new executor with zeroed registers.

pub fn set_uniform(&mut self, slot: usize, value: UniformValue)

Set a uniform value for the next execution.

pub fn set_register(&mut self, reg: u8, value: i32)

Set an input register value.

pub fn get_register(&self, reg: u8) -> i32

Read a register value.

pub fn execute(&mut self, program: &ShaderProgram)

Execute a shader program.

Registers should be pre-loaded with input values. After execution, output registers contain the results.

pub fn execute_fragment(&mut self, program: &ShaderProgram) -> u32

Execute a fragment shader for a single pixel, returning ARGB8888.

Input: registers 0-3 are R, G, B, A in 16.16 fixed-point (0..255 range).

Trait Implementations

impl Default for ShaderExecutor

fn default() -> Self

Returns the “default value” for a type.
