Member Function Documentation

void CLightParam::FromString ( const char * str )

convert a string returned by ToString() to this object.

void CLightParam::MakeWhitePointLight ( )

make the current light a white point light with default value.

const char * CLightParam::ToString ( )

return the parameters as a string.

This is usually used for serialization. format is "Type Range (r g b a) att0 att1 att2" D3DLIGHTTYPE Type; Type of light source

D3DLIGHT_POINT = 1,
D3DLIGHT_SPOT = 2,
D3DLIGHT_DIRECTIONAL = 3, float Range; Cutoff range D3DCOLORVALUE Diffuse; Diffuse color of light float Attenuation0; Constant attenuation float Attenuation1; Linear attenuation float Attenuation2; Quadratic attenuation e.g. "1 7.0 (1 1 0 1) 0.3 0.1 1" light intensity is calculated as 1/(Attenuation0+d*Attenuation1+d*d*Attenuation2), where d is the distance from the light to object center.
