Detailed Description

Field Documentation

acquired_buffer

int32_t comp_renderer::acquired_buffer

Index of the current buffer/image.

buffer_count

uint32_t comp_renderer::buffer_count

The number of renderings/fences we've created: set from comp_target when we use that data.

Referenced by renderer_create_renderings_and_fences().

c

struct comp_compositor* comp_renderer::c

The compositor we were created by.

Referenced by comp_renderer_create(), renderer_create_renderings_and_fences(), scratch_get_fini(), and scratch_get_init().

fenced_buffer

int32_t comp_renderer::fenced_buffer

Which buffer was last submitted and has a fence pending.

fences

VkFence* comp_renderer::fences

Array of fences equal in size to the number of comp_target images.

Referenced by renderer_create_renderings_and_fences().

rtr_array

struct render_gfx_target_resources* comp_renderer::rtr_array

Array of "rendering" target resources equal in size to the number of comp_target images.

Each target resources holds all of the resources needed to render to that target and its views.

Referenced by renderer_create_renderings_and_fences().

scratch_render_pass

struct render_gfx_render_pass comp_renderer::scratch_render_pass

Render pass for graphics pipeline rendering to the scratch buffer.

target_render_pass

struct render_gfx_render_pass comp_renderer::target_render_pass

The render pass used to render to the target, it depends on the target's format so will be recreated each time the target changes.

Referenced by renderer_create_renderings_and_fences().

targets

struct render_gfx_target_resources comp_renderer::targets[COMP_SCRATCH_NUM_IMAGES]

Targets for rendering to the scratch buffer.
