Struct conrod_vulkano::Renderer

pub struct Renderer { /* private fields */ }

A type used for translating render::Primitives into Commands that indicate how to draw the conrod GUI using vulkano.

Implementations

impl Renderer

pub fn new(
    device: Arc<Device>,
    subpass: Subpass,
    graphics_queue_family: QueueFamily<'_>,
    window_dims: [u32; 2],
    dpi_factor: f64
) -> Result<Self, RendererCreationError>

Construct a new empty Renderer.

The dimensions of the glyph cache will be the dimensions of the window multiplied by the DPI factor.

pub fn with_glyph_cache_dimensions(
    device: Arc<Device>,
    subpass: Subpass,
    graphics_queue_family: QueueFamily<'_>,
    glyph_cache_dims: [u32; 2]
) -> Result<Self, RendererCreationError>

Construct a new empty Renderer.

pub fn commands(&self) -> Commands<'_>

Produce an Iterator yielding Commands.

pub fn fill<P: PrimitiveWalker>(
    &mut self,
    image_map: &Map<Image>,
    viewport: [f32; 4],
    dpi_factor: f64,
    primitives: P
) -> Result<Option<GlyphCacheCommand<'_>>, CacheWriteErr>

Fill the inner vertex and command buffers by translating the given primitives.

This method may return an Option<GlyphCacheCommand>, in which case the user should use the contained glyph_cpu_buffer_pool to write the pixel data to the GPU, and then use a copy_buffer_to_image command to write the data to the given glyph_cache_texture image.

pub fn draw(
    &mut self,
    queue: Arc<Queue>,
    image_map: &Map<Image>,
    viewport: [f32; 4]
) -> Result<Vec<DrawCommand>, DrawError>

Draws using the inner list of Commands to a list of DrawCommands compatible with the vulkano command buffer builders.

Uses the given queue for submitting vertex buffers.

Note: If you require more granular control over rendering, you may want to use the fill and commands methods separately. This method is simply a convenience wrapper around those methods for the case that the user does not require accessing or modifying conrod’s draw parameters, uniforms or generated draw commands.
