debug_draw()

void blender::eevee::HiZBuffer::debug_draw	(	View &	view,
		gpu::FrameBuffer *	view_fb )

Definition at line 110 of file eevee_hizbuffer.cc.

References blender::eevee::DEBUG_HIZ_VALIDATION, GPU_framebuffer_bind(), and view.

set_dirty()

void blender::eevee::HiZBuffer::set_dirty ( )

inline

Tag the front buffer for update if needed.

Referenced by swap_layer().

set_source()

void blender::eevee::HiZBuffer::set_source ( gpu::Texture ** texture, int layer = -1 )

inline

Set source texture for the hiz down-sampling. Need to be called once at the start of a pipeline or view. Tag the buffer as dirty.

Definition at line 69 of file eevee_hizbuffer.hh.

References swap_layer(), and texture().

swap_layer()

void blender::eevee::HiZBuffer::swap_layer ( )

inline

Swap front and back layer. Internally set front layer to be dirty. IMPORTANT: Before the second swap (and the second update) the content of the back hi-z buffer is undefined.

Definition at line 82 of file eevee_hizbuffer.hh.

References back, front, and set_dirty().

update()

void blender::eevee::HiZBuffer::update

(

)

Update the content of the HiZ buffer with the source depth set by set_source(). Noop if the buffer has not been tagged as dirty. Should be called before each passes that needs to read the hiz buffer.
