[−][src]Struct wgpu::RenderPass
An in-progress recording of a render pass.
Methods
impl<'a> RenderPass<'a>
[src]
pub fn set_bind_group(
&mut self,
index: u32,
bind_group: &BindGroup,
offsets: &[BufferAddress]
)
[src]
&mut self,
index: u32,
bind_group: &BindGroup,
offsets: &[BufferAddress]
)
Sets the active bind group for a given bind group index.
pub fn set_pipeline(&mut self, pipeline: &RenderPipeline)
[src]
Sets the active render pipeline.
Subsequent draw calls will exhibit the behavior defined by pipeline
.
pub fn set_blend_color(&mut self, color: Color)
[src]
pub fn set_index_buffer(&mut self, buffer: &Buffer, offset: BufferAddress)
[src]
Sets the active index buffer.
Subsequent calls to draw_indexed
on this RenderPass
will
use buffer
as the source index buffer.
pub fn set_vertex_buffers(
&mut self,
start_slot: u32,
buffer_pairs: &[(&Buffer, BufferAddress)]
)
[src]
&mut self,
start_slot: u32,
buffer_pairs: &[(&Buffer, BufferAddress)]
)
Sets the active vertex buffers, starting from start_slot
.
Each element of buffer_pairs
describes a vertex buffer and an offset in bytes into that
buffer. The offset must be aligned to a multiple of 4 bytes.
pub fn set_scissor_rect(&mut self, x: u32, y: u32, w: u32, h: u32)
[src]
Sets the scissor region.
Subsequent draw calls will discard any fragments that fall outside this region.
pub fn set_viewport(
&mut self,
x: f32,
y: f32,
w: f32,
h: f32,
min_depth: f32,
max_depth: f32
)
[src]
&mut self,
x: f32,
y: f32,
w: f32,
h: f32,
min_depth: f32,
max_depth: f32
)
Sets the viewport region.
Subsequent draw calls will draw any fragments in this region.
pub fn set_stencil_reference(&mut self, reference: u32)
[src]
Sets the stencil reference.
Subsequent stencil tests will test against this value.
pub fn draw(&mut self, vertices: Range<u32>, instances: Range<u32>)
[src]
Draws primitives from the active vertex buffer(s).
The active vertex buffers can be set with RenderPass::set_vertex_buffers
.
pub fn draw_indexed(
&mut self,
indices: Range<u32>,
base_vertex: i32,
instances: Range<u32>
)
[src]
&mut self,
indices: Range<u32>,
base_vertex: i32,
instances: Range<u32>
)
Draws indexed primitives using the active index buffer and the active vertex buffers.
The active index buffer can be set with RenderPass::set_index_buffer
, while the active
vertex buffers can be set with RenderPass::set_vertex_buffers
.
