Hi everyone,i have some trouble in frame selection, when i select the primitives in the frame. it just select the visible primitives, but the invisible primitives con’be selected. there is my code,any answer is well received.
byte[] pixels = new byte[(width * 3) * height];
gl.ReadBuffer(0x405);
gl.PixelStorei(0xd05, 1);
gl.ReadPixels(x, num3, width, height, 0x1907, 0x1401, pixels);
int num7 = -1;
int num8 = width * height;
for (int i = 0; i < num8; i++)
{
int index = i * 3;
int item = (pixels[index] + (pixels[index + 1] << 8)) + (pixels[index + 2] << 0x10);
if ((item < base.entities.Count) && (item != num7))
{
if (!list.Contains(item))
{
list.Add(item);
}
num7 = item;
}
}
