C++ (Cpp) GetSunlightDirection Examples

Example #1

File: LightEnv.cpp Project: BruteSolutions/gltut

LightBlock LightEnv::GetLightBlock( const glm::mat4 &worldToCamera ) const
{
	LightBlock lightData;
	lightData.ambientIntensity = m_ambientInterpolator.Interpolate(m_sunTimer.GetAlpha());
	lightData.lightAttenuation = m_fLightAttenuation;
	lightData.maxIntensity = m_maxIntensityInterpolator.Interpolate(m_sunTimer.GetAlpha());

	lightData.lights[0].cameraSpaceLightPos =
		worldToCamera * GetSunlightDirection();
	lightData.lights[0].lightIntensity = m_sunlightInterpolator.Interpolate(m_sunTimer.GetAlpha());

	for(size_t light = 0; light < m_lightPos.size(); light++)
	{
		glm::vec4 worldLightPos = glm::vec4(GetPointLightWorldPos(light), 1.0f);
		glm::vec4 lightPosCameraSpace = worldToCamera * worldLightPos;

		lightData.lights[light + 1].cameraSpaceLightPos = lightPosCameraSpace;
		lightData.lights[light + 1].lightIntensity = m_lightIntensity[light];
	}

	return lightData;
}
