Detailed Description

template<int MAX_SPOT_LIGHTS>
struct tgx::Renderer3D_detail::SpotLightData< MAX_SPOT_LIGHTS >

Internal storage for local spot lights.

A point light is represented as a spot light without SPOT_LIGHT_CONE_ENABLED. The arrays are split by field instead of grouped per light so the render loop may touch only the values needed by each branch.
