Struct three_d::core::RenderTarget

pub struct RenderTarget<'a, 'b, T: TextureValueType> { /* fields omitted */ }

Adds additional functionality to write to and copy from both a ColorTargetTexture2D and a DepthTargetTexture2D at the same time. It purely adds functionality, so it can be created each time it is needed, the data is saved in the textures.

Implementations

impl<'a, 'b, T: TextureValueType> RenderTarget<'a, 'b, T>

pub fn new(
    context: &Context,
    color_texture: &'a ColorTargetTexture2D<T>,
    depth_texture: &'b DepthTargetTexture2D
) -> Result<Self, Error>

Constructs a new render target that enables rendering into the given color and depth textures.

pub fn write<F: FnOnce() -> Result<(), Error>>(
    &self,
    clear_state: ClearState,
    render: F
) -> Result<(), Error>

Renders whatever rendered in the render closure into the textures defined at construction. Before writing, the textures are cleared based on the given clear state.

pub fn copy_to(
    &self,
    destination: CopyDestination<'_, '_, '_, '_, T>,
    viewport: Viewport,
    write_mask: WriteMask
) -> Result<(), Error>

Copies the content of the color and depth textures in this render target to the specified viewport of the specified destination. Only copies the channels given by the write mask.
