示例1: Sample
// protected functions:
CColor CRenderingCore::Sample(float x, float y, int curDepth)
{
CColor colArray[5];
CColor finalCol;
int colCount = 1;
double dXFraction;
double dYFraction;
/*******************************************************************
STRATEGY:
1. First compute the color for the central pixel.
2. Check if we have to dive further into the oversampling recursion.
3. Average the colors.
4. Return the color.
*******************************************************************/
// 1.
/***********************************************************
SUB_STEPS:
1.1. Calculate the x and y fractions.
1.2. Get the corresponding ray from the camera.
1.3. Test the scene to see which object intersects the ray.
1.4. Query the object for teh color of the point.
