Struct GpuDensityRenderer 

pub struct GpuDensityRenderer {
    pub drawn: u32,
    /* private fields */
}

The GL side: one program, one quad, no per-particle data at all.

Fields

drawn: u32

Particles drawn last frame, for the stats.

Implementations

impl GpuDensityRenderer

pub unsafe fn new(gl: &Context) -> Self

pub unsafe fn draw( &mut self, gl: &Context, entities: &[GpuDensityEntityData], budget: u32, view_proj: &Mat4, viewport: (u32, u32), time: f32, ) -> u32

Draw every entity into whatever framebuffer is bound. The caller has set the viewport; this sets and restores the blend mode.

pub unsafe fn destroy(&self, gl: &Context)
