Member Function Documentation

void IND_Light::SetColor	(	float	pR,
		float	pG,
		float	pB,
		float	pA
	)

Parameters:

• pR Float R (Red)
• pG Float G (Green)
• pB Float B (Blue)

Operation:

Sets the light color. The color is specified using three floats (red, green and blue values). Usually you will use the range between 0.0f and 1.0f. The higer the value the nearest to the color. For example, red color will be: (1.0f, 0.0f, 0.0f).

Using values higher that 1.0f will increase the light intensity.

By Default: (1.0f, 1.0f, 1.0f)

void IND_Light::SetPosition	(	float	pX,
		float	pY,
		float	pZ
	)

Parameters:

• pX, pY, pZ Position in the space

Operation:

Sets the light position.

By default: (0, 0, 0)

void IND_Light::SetDirection	(	float	pD1,
		float	pD2,
		float	pD3
	)

Parameters:

• pD1, pD2, pD3 The three coordinates define a vector with the direction of the light

Operation:

Sets the light direction. This value is used for IND_DIRECTIONAL_LIGHT and IND_SPOT_LIGHT lights.

For example, for a Sun light, you can choose a direction: (0.0f, -0.3f, 0.5) with a IND_DIRECTIONAL_LIGHT.

By default: (0, 0, 0)

void IND_Light::SetAttenuation

(

float

pAttenuation

)

Parameters:

• pAttenuation Attenuation factor

Operation:

Sets the light attenuation. This value is used for IND_POINT_LIGHT and IND_SPOT_LIGHT lights.

By default: (0)

void IND_Light::SetRange

(

float

pRange

)

Parameters:

• pRange Range factor

Operation:

Sets the light range. This value is used for IND_DIRECTIONAL_LIGHT, IND_POINT_LIGHT and IND_SPOT_LIGHT lights.

By default: (0)

void IND_Light::SetTheta

(

float

pTheta

)

Parameters:

• pTheta Theta factor

Operation:

Sets the light theta factor. This value is used for IND_SPOT_LIGHT lights.

By default: (0)

void IND_Light::SetPhi

(

float

pPhi

)

Parameters:

• pPhi Phi factor

Operation:

Sets the light phi factor. This value is used for IND_SPOT_LIGHT lights.

By default: (0)

void IND_Light::SetFalloff

(

float

pFalloff

)

Parameters:

• pPhi Phi factor

Operation:

Sets the light falloff factor. This value is used for IND_SPOT_LIGHT lights.

By default: (0)
