示例1: CalculateSpecularLighting
Colour RayTracer::CalculateSpecularLighting(Vector3 &surfacePoint, Vector3 &surfaceNormal, Vector3 &lightPosition, Vector3 &cameraPosition, Light &light, Material &material)
{
Colour specular;
Vector3 halfVector = Vector3::HalfVector(cameraPosition, surfacePoint, lightPosition);
double angle = halfVector.DotProduct(surfaceNormal);
double power = powf(angle, material.GetSpecPower());
specular.red = light.GetLightColour().red * material.GetSpecularColour().red * power;
specular.green = light.GetLightColour().green * material.GetSpecularColour().green * power;
specular.blue = light.GetLightColour().blue * material.GetSpecularColour().blue * power;
return specular;
}示例2: CalculateDiffuseLighting
Colour RayTracer::CalculateDiffuseLighting(Vector3 &lightNormal, Vector3 &surfaceNormal, Light &light, Material &material)
{
Colour diffuse;
double angle = lightNormal.DotProduct(surfaceNormal);
if (angle > 0.0)
{
diffuse.red = light.GetLightColour().red * material.GetDiffuseColour().red * angle;
diffuse.green = light.GetLightColour().red * material.GetDiffuseColour().green * angle;
diffuse.blue = light.GetLightColour().red * material.GetDiffuseColour().blue * angle;
}
return diffuse;
