Struct web_glitz::rendering::FloatBuffer

pub struct FloatBuffer<F> { /* fields omitted */ }

Represents a color buffer that stores floating point values in a framebuffer for a custom render target.

Implementations

impl<F> FloatBuffer<F>

pub fn clear_command(
    &self,
    clear_value: [f32; 4],
    region: Region2D
) -> ClearFloatCommand

Returns a command that clears all pixel values in the region to clear_value.

Values outside the region are unaffected.

Examples

The following command will clear the entire buffer to a value of "transparent black":

let command = buffer.clear_command([0.0, 0.0, 0.0, 0.0], Region2D::Fill);

It's also possible to only clear a specific rectangular area of the buffer:

let command = buffer.clear_command([0.0, 0.0, 0.0, 0.0], Region2D::Area((0, 0), 100, 100));
