Functions

`mk_particle_alive_count`function

uint32_t mk_particle_alive_count(const mk_particle_world_t *world, mk_particle_instance_t instance, uint32_t emitter_index)

Return the exact CPU alive count.

GPU-authoritative emitters return a conservative upper bound because simulation counters remain device-local.

Parameter	Type	Description
`world`	`const mk_particle_world_t *`	Value for world.
`instance`	`mk_particle_instance_t`	Value for instance.
`emitter_index`	`uint32_t`	Value for emitter index.

Returns The resulting value.

`mk_particle_apply_gpu_draw`function

mk_result mk_particle_apply_gpu_draw(mk_particle_world_t *world, mk_particle_instance_t instance, uint32_t emitter_index, struct mk_draw_desc *draw)

Attach a prepared GPU sprite, billboard, mesh, or trail emitter to a custom draw descriptor.

For sprites and billboards, the caller supplies a particle-compatible shader or pipeline plus a valid indexed or non-indexed quad in draw->geometry. The shader reads a_position/a_texcoord0 for the corner and UV. The adapter fills the dynamic instance source and indirect draw fields. Its 64-byte instance ABI is: i_data0 = simulation-space position.xyz, age i_data1 = velocity.xyz, lifetime i_data2 = color i_data3 = size, rotation, initial size, angular velocity Trail renderers instead fill the ordinary dynamic vertex stream. Their 64-byte vertex ABI (TEXCOORD7 through TEXCOORD4) is: data0 = simulation-space center.xyz, side (-1 or +1) data1 = normalized trail tangent.xyz, distance-based u data2 = particle color * color-over-trail data3 = width, normalized trail coordinate, reserved, reserved The graphics shader expands center along side using its camera basis. Mesh emitters use geometry previously registered through mk_particle_mesh_set_geometry(); the adapter fills its retained vertex/index streams. Call only after mk_particle_world_prepare_gpu() in the current open frame. Existing raw vertex/index, instance, or indirect fields are rejected; geometry is accepted only for sprites and billboards. GPU trail sorting is intrinsic oldest-to-newest and requires MK_PARTICLE_SORT_NONE.
