Function Documentation

◆ GPU_select_begin()

void GPU_select_begin	(	GPUSelectBuffer *	buffer,
		const rcti *	input,
		GPUSelectMode	mode,
		int	oldhits )

Initialize and provide buffer for results.

◆ GPU_select_begin_next()

void GPU_select_begin_next	(	GPUSelectBuffer *	buffer,
		const rcti *	input,
		GPUSelectMode	mode,
		int	oldhits )

Initialize and provide buffer for results. Uses the new Select-Next engine if enabled.

◆ GPU_select_buffer_near()

const GPUSelectResult * GPU_select_buffer_near ( const blender::Span< GPUSelectResult > hit_results )

Helper function, nothing special but avoids doing inline since hits aren't sorted by depth and purpose of 4x buffer indices isn't so clear.

Note that comparing depth as uint is fine.

◆ GPU_select_end()

unsigned int GPU_select_end ( )

Cleanup and flush selection results to buffer. Return number of hits and hits in buffer. if dopass is true, we will do a second pass with occlusion queries to get the closest hit.

◆ GPU_select_load_id()

bool GPU_select_load_id ( unsigned int id )

Loads a new selection id and ends previous query, if any. In second pass of selection it also returns if id has been hit on the first pass already. Thus we can skip drawing un-hit objects.

Warning: We rely on the order of object rendering on passes to be the same for this to work.
