C++ (Cpp) ClearSolidSegments Examples

Example #1

File: r_poly_cull.cpp Project: Xane123/world-of-kirbycraft

void PolyCull::CullScene(const TriMatrix &worldToClip)
{
    ClearSolidSegments();
    PvsSectors.clear();
    frustumPlanes = FrustumPlanes(worldToClip);

    // Cull front to back
    if (numnodes == 0)
    {
        PvsSectors.push_back(subsectors);
        MaxCeilingHeight = subsectors->sector->ceilingplane.Zat0();
        MinFloorHeight = subsectors->sector->floorplane.Zat0();
    }
    else
    {
        MaxCeilingHeight = 0.0;
        MinFloorHeight = 0.0;
        CullNode(nodes + numnodes - 1);	// The head node is the last node output.
    }

    ClearSolidSegments();
}

Example #2

File: poly_cull.cpp Project: JPLeBreton/gzdoom

void PolyCull::InvertSegments()
{
	TempInvertSolidSegments.swap(SolidSegments);
	ClearSolidSegments();
	angle_t cur = 0;
	for (const auto &segment : TempInvertSolidSegments)
	{
		if (cur < segment.Start)
			MarkSegmentCulled(cur, segment.Start - 1);
		cur = segment.End + 1;
	}
	if (cur < ANGLE_MAX)
		MarkSegmentCulled(cur, ANGLE_MAX);
}
