Module fna3h::draw

Drawing

Rendering cycle

As described in crate::Device, one rendering pass is as follows:

• Device::clear
• for each draw call:
  • (set shader matrix)
  • apply pipeline
    • Device::apply_effect (mojo::Effect)
    • Device::set_vertex_buffer_data (crate::buf)
    • Device::verify_sampler (pip::SamplerState)
  • Device::apply_vertex_buffer_bindings (VertexBufferBinding)
  • Device::draw_indexed_primitives: (range of vertex buffer and index buffer)

And call Device::swap_buffers at the end of a frame.
