Struct ggraphics::RenderPass

pub struct RenderPass {
    pub pipelines: Vec<Box<dyn Pipeline>>,
    // some fields omitted
}

Currently, no input framebuffers or such. We're not actually intending to reproduce Rendy's Graph type here. This may eventually feed into a bounce buffer or such though.

Fields

pipelines: Vec<Box<dyn Pipeline>>

The pipelines to draw in the render pass.

Methods

impl RenderPass

pub unsafe fn new(
    ctx: &mut GlContext,
    width: usize,
    height: usize,
    clear_color: (f32, f32, f32, f32)
) -> Self

Make a new render pass rendering to a texture.

pub unsafe fn new_screen(
    _ctx: &mut GlContext,
    width: usize,
    height: usize,
    clear_color: (f32, f32, f32, f32)
) -> Self

Create a new rnder pass rendering to the screen.

pub fn add_pipeline(&mut self, pipeline: impl Pipeline + 'static)

Add a new pipeline to the renderpass

pub fn get_texture(&self) -> Option<Texture>

Get the texture this render pass outputs to, if any.

pub fn set_viewport(&mut self, x: i32, y: i32, w: i32, h: i32)

Sets the viewport for the render pass. Negative numbers are valid, see glViewport for the math involved.
