Detailed Description

Deferred so lighting runs once per visible voxel pixel not once per march.

Member Function Documentation

◆ name()

auto renderer::VoxelPass::name ( ) const -> std::string_view

inlinenodiscardoverridevirtual

Reimplemented from IRenderPass.

◆ prepare()

auto renderer::VoxelPass::prepare ( uint32_t frame_index ) -> bool

nodiscard

Returns: false when nothing draws so the caller skips both voxel scopes

Here is the caller graph for this function:

◆ record()

void renderer::VoxelPass::record	(	vk::CommandBuffer	cmd,
		uint32_t	frame_index,
		uint32_t	image_index )

overridevirtual

Inside the voxel G-buffer scope after prepare() for everything the previous pyramid did not hide.

Implements IRenderPass.

Here is the caller graph for this function:

◆ stage()

auto renderer::VoxelPass::stage ( ) const -> RenderStage
