PicaDataFragLightEnvLutInput Enumerated Typeenum PicaDataFragLightEnvLutInput;
| Value | Description |
|---|---|
| PICA_DATA_FRAG_LIGHT_ENV_NH_DMP | The cosine of the angle between the normal and the half vector. |
| PICA_DATA_FRAG_LIGHT_ENV_VH_DMP | The cosine of the angle between the line of sight and the half vector. |
| PICA_DATA_FRAG_LIGHT_ENV_NV_DMP | The cosine of the angle between the normal and the line of sight. |
| PICA_DATA_FRAG_LIGHT_ENV_LN_DMP | The cosine of the angle between the light vector and the normal. |
| PICA_DATA_FRAG_LIGHT_ENV_SP_DMP | The cosine of the angle between the reciprocal vector of the light vector and the spotlight's directional vector. |
| PICA_DATA_FRAG_LIGHT_ENV_CP_DMP | The cosine of the angle between the projection of the half vector of the tangent plane and the tangent. |
Used for the PICA_REG_FRAG_LIGHT_LUTINPUT register (0x1d1), which is used for setting lookup table entries. This corresponds to setting the dmp_LightEnv.lutInput* uniform.
