Implementations

impl Screen

pub fn write<F: FnOnce() -> ThreeDResult<()>>(
    context: &Context,
    clear_state: ClearState,
    render: F
) -> ThreeDResult<()>

Call this function and make a render call (for example one of the draw functions on Program) in the render closure to render something to the screen. Before writing, the screen is cleared based on the given clear state.

pub fn read_color(
    context: &Context,
    viewport: Viewport
) -> ThreeDResult<Vec<u8>>

Returns the RGBA color values from the screen as a list of bytes (one byte for each color channel).

pub fn read_depth(
    context: &Context,
    viewport: Viewport
) -> ThreeDResult<Vec<f32>>

This is supported on non-WebAssembly only.

Returns the depth values from the screen as a list of 32-bit floats. Only available on desktop.
