Description

A light in the Metal render scene, in the packed form the GPU consumes.

This is the Metal analogue of ChOptixLight. It is deliberately NOT ChOptixLight: that struct is built from CUDA vector types (float3, cudaTextureObject_t, curand state), so reusing it would drag the CUDA toolchain into a Metal-only build. The public setters above convert into this form, so the difference is invisible to simulation code.

Public Attributes
ChVector3f	pos
	world position (point/spot); for directional, the light TRAVEL direction

float	range
	max_range (point/spot falloff; 0 = none)

ChColor	color
	color * intensity

int	type
	0 = point, 1 = directional, 2 = spot, 3 = disk, 4 = rectangle

ChVector3f	dir {0, 0, -1}
	spot axis / disk normal / rectangle edge-1

float	cosOuter = -1.f
	spot: angle_range (full cone, rad) \| rect: edge-2 .x

float	cosInner = -1.f
	spot: angle_atten_rate \| rect: edge-2 .y

float	p0 = 0.f
	disk: radius \| rect: edge-2 .z

bool	const_color = true
	constant colour (no distance attenuation)
