Ninja Library - Light Function

njCnkSetEasyMultiLightRange

Sets the effective light range of the light source for the chunk EasyMulti light (point light source)

FORMAT

void njCnkSetEasyMultiLightRange( light, nrange, frange )
Int light
Float nrange
Float frange

PARAMETER

 light  Light number 
 nrange  Range that the maximum intensity of the light reaches (upper limit clamp) 
 frange  Range reach of the position light (cut-off) 

RETURN

None

DESCRIPTION

Sets the effective range of the point light source for the njCnkEasyMultiDrawObject (njCnkEasyMultiDrawModel). Enter the light number and the maximum intensity range (uniform value) and range reach (the light is cut off at this value) to be used in the parameters.

EXAMPLE

sbInitSystem( NJD_RESOLUTION_640x240_NTSCNI, NJD_FRAMEBUFFER_MODE_RGB565, 1 );
njInitVertexBuffer( 1000000, 0, 1000, 0, 0 );
njInitMatrix( matrix, 8 , 0);
njInit3D( vbuf, 4096 );
njInitView( &view );
njSetView( &view );
/* Set chunk light as 4 */
njCnkSetEasyMultiLight( 4 );
/* Set direction of chunk light's parallel light source (first light source) */
njCnkSetEasyMultiLightVector(0.f, 0.f, -1.f);
/* Set chunk light's point light source position */
/* Set second light source (point light source) */
njCnkSetEasyMultiLightPoint(NJD_CNK_EASY_MULTILIGHT_2, 0.f, 0.f, -12.f);
/* Set third light source (point light source) */
njCnkSetEasyMultiLightPoint(NJD_CNK_EASY_MULTILIGHT_3, 0.f, 0.f, -12.f);
/* Set chunk light's point light source range (distance) */
njCnkSetEasyMultiLightRange(NJD_CNK_EASY_MULTILIGHT_2, 6.f, 40.f);
njCnkSetEasyMultiLightRange(NJD_CNK_EASY_MULTILIGHT_3, 6.f, 40.f);
njCnkSetEasyMultiLightRange(NJD_CNK_EASY_MULTILIGHT_4, 6.f, 40.f);
/* Set chunk light's ambient color */
njCnkSetEasyMultiAmbient(0.1f, 0.1f, 0.1f);
/* Set the chunk light's light source color */
njCnkSetEasyMultiLightColor(NJD_CNK_EASY_MULTILIGHT_1, 0.6f, 0.5f, 0.3f);
njCnkSetEasyMultiLightColor(NJD_CNK_EASY_MULTILIGHT_2, 1.f, 0.5f, 0.5f);
njCnkSetEasyMultiLightColor(NJD_CNK_EASY_MULTILIGHT_3, 0.5f, 1.f, 0.5f);
njCnkSetEasyMultiLightColor(NJD_CNK_EASY_MULTILIGHT_4, 0.5f, 0.5f, 1.f);
	:
njClearMatrix();
/* Set chunk light direction-position reflection */
njCnkSetEasyMultiLightMatrices();
njTranslate( NULL, 0.f, 0.f, -10.f );
njRotateXYZ( NULL, rx,ry,rz );
