| struct | iLight |
| The iLight interface is the SCF interface for the csLight class. More... | |
| struct | iLightCallback |
| Set a callback which is called when this light color is changed. More... | |
| struct | iLightingProcessData |
| The iLightingProcessData interface can be implemented by a mesh object so that it can attach additional information for the lighting process. More... | |
| struct | iLightingProcessInfo |
| The iLightingProcessInfo interface holds information for the lighting system. More... | |
| struct | iLightIterator |
| Iterator to iterate over all static lights in the engine. More... | |
| struct | iLightList |
| This structure represents a list of lights. More... | |
Light flags | |
| #define | CS_LIGHT_THINGSHADOWS 0x00000001 |
| If CS_LIGHT_THINGSHADOWS is set for a light then things will also cast shadows. | |
| #define | CS_LIGHT_ACTIVEHALO 0x80000000 |
| If this flag is set, the halo for this light is active and is in the engine's queue of active halos. | |
Light Dynamic Types | |
| #define | CS_LIGHT_DYNAMICTYPE_STATIC 1 |
| A fully static light. | |
| #define | CS_LIGHT_DYNAMICTYPE_PSEUDO 2 |
| A pseudo-dynamic light. | |
| #define | CS_LIGHT_DYNAMICTYPE_DYNAMIC 3 |
| A fully dynamic light. | |
Attenuation modes | |
| Attenuation controls how the brightness of a light fades with distance.
There are five attenuation formulas:
| |
| #define | CS_ATTN_NONE 0 |
| no attenuation: light * 1 | |
| #define | CS_ATTN_LINEAR 1 |
| linear attenuation: light * (radius - distance) / radius | |
| #define | CS_ATTN_INVERSE 2 |
| inverse attenuation: light * (radius / distance) | |
| #define | CS_ATTN_REALISTIC 3 |
| realistic attenuation: light * (radius^2 / distance^2) | |
| #define | CS_ATTN_CLQ 4 |
| using clq attenuation | |
Defines | |
| #define | CS_DEFAULT_LIGHT_LEVEL 20 |
| Light level that is used when there is no light on the texture. | |
| #define | CS_NORMAL_LIGHT_LEVEL 128 |
| Light level that corresponds to a normally lit texture. | |
