tz::gpu::draw_t Struct Reference

Description

Represents a single unindexed draw-call.

See pass_graphics_state::draw_buffer for details.

#include "resource.hpp"

Public Attributes
std::uint32_t	vertex_count = 0
	Number of vertices to draw.
std::uint32_t	instance_count = 1
	Number of instances to draw. If you're not doing GPU instancing, you probably want this to be 1.
std::uint32_t	first_vertex = 0
	Index of the first vertex to draw. Essentially offsets gl_VertexIndex. (TODO: confirm that this is true)
std::uint32_t	first_instance = 0
	Instance ID of the first instance to draw.
